Answer:
Explanation:
In programming, it is very important that element ID's have meaningful names because it allows anyone reading the code to be able to easily identify what that element is and where it is most likely to be found in the code. This also applies to variables in every programming language. The clearer and more unique the name is the easier it becomes to know what that variable or element ID is representing which ultimately makes reading and debugging the code that much easier. This means that the entire process becomes more efficient as well.
It is vital for element IDs to have meaningful names due to the fact that it allows easy identification of the codes.
Element IDs refer to the id property of the interface of the element. It should be noted that the id property is unique in a document.
Element IDs should have meaningful names due to the fact that it allows east identification of the codes. This makes it easy for the person reading the code to identify them easily. The uniqueness of an element ID is vital to know what it represents.

This program will calculate the rise in ocean levels over 5, 10, and 50 years, Part of the program has been written for you. The part that has been written will read in a rise in ocean levels (per year) in millimeters. This value is read into a variable of type double named risingLevel. You will be completing the program as follows Output the value in risingLevel. This should be the first line of output. The output should be as follows (assume risingLevel has a value of 2.1) Level: 2.1 The number of millimeters higher than the current level that the ocean's level will be in 5 years (assuming the ocean is rising at the rate of risingLevel per year). This is your second line of output. The output will be as follows Years: 5, Rise: 10.5 The number of millimeters higher than the current level that the ocean's level will be in 10 years (assuming the ocean is rising at the rate of risingLevel per year). This is your third line of output. The output will be as follows (for a risingLevel" of 2.1 Years: 10, Rise: 21 The number of millimeters higher than the current level that the ocean's level will be in 50 years (assuming the ocean is rising at the rate of risingLevel per year). This is your final line of output.The output will be as follows (for a risingLevel" of 2.1) Years: 50, Rise: 105 For each of the above you need to output the number of years and the total rise in ocean levels for those years. This is all based on the value in risingLevel For example: ArisingLevel of 2.1 for 5 years would have the following output: Level: 2.1 Years: 5, Rise: 10.5 Years: Years: 50, Rise: 105 10, Rise: 21 Your output must have the same syntax and spacing as above
Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main(){ //start of main method
double risingLevel; //declares a double type variable to hold rising level
cin>>risingLevel; //reads the value of risingLevel from user
cout<<"Level: "<<risingLevel<<endl; //displays the rising level
cout << "Years: 5, Rise: " << risingLevel * 5<<endl; //displays the rise in ocean level over 5 years
cout << "Years: 10, Rise: " << risingLevel * 10<<endl; //displays the rise in ocean level over 10 years
cout << "Years: 50, Rise: " << risingLevel * 50<<endl; //displays the rise in ocean level over 50 years
}
Explanation:
The program works as follows:
Lets say the user enters rising level 2.1 then,
risingLevel = 2.1
Now the first print (cout) statement :
cout<<"Level: "<<risingLevel<<endl; prints the value of risingLevel on output screen. So this statement displays:
Level: 2.1
Next, the program control moves to the statement:
cout << "Years: 5, Rise: " << risingLevel * 5<<endl;
which computes the rise in ocean levels over 5 years by formula:
risingLevel * 5 = 2.1 * 5 = 10.5
It then displays the computed value on output screen. So this statement displays:
Years: 5, Rise: 10.5 Next, the program control moves to the statement:
cout << "Years: 10, Rise: " << risingLevel * 10<<endl;
which computes the rise in ocean levels over 10 years by formula:
risingLevel * 10 = 2.1 * 10 = 21
It then displays the computed value on output screen. So this statement displays:
Years: 10, Rise: 21
Next, the program control moves to the statement:
cout << "Years: 50, Rise: " << risingLevel * 50<<endl;
which computes the rise in ocean levels over 50 years by formula:
risingLevel * 50 = 2.1 * 50 = 105
It then displays the computed value on output screen. So this statement displays:
Years: 50, Rise: 105 Hence the output of the entire program is:
Level: 2.1 Years: 5, Rise: 10.5 Years: 10, Rise: 21 Years: 50, Rise: 105
The screenshot of the program and its output is attached.

Write a loop that inputs words until the user enters STOP. After each input, the program should number each entry and print in this format:
(This code must be in python, also if a minor explanation can be added to the bottom that would be nice. But also long as u can help I will be fine)
i = 0
while True:
user_input = input("Please enter the next word: ")
if user_input == "STOP":
break
i += 1
print("#{}: You entered {}".format(i,user_input))
print("All done. {} words entered.".format(i))
First we set i equal to zero so that we can keep track of how many words we input.
We set while True so that its a continuous loop until a certain condition is met to break out of the loop.
user_input is set equal to whatever word the user enters.
our if statement tells us to break out of the while loop if the user inputs "STOP"
If the user does not enter STOP i is set equal to itself plus 1. This just means we add one to i for every new word entered.
Then we print whichever word is entered.
After the while loop, we print All done and the quantity of words entered.
Answer:
c = 0
word = input("Enter a word: ")
while word!="STOP":
c = c+1
print("#" + str(c) + ": You entered "+str(word))
word = input("Please enter the next word: ")
print("All done. "+str(c)+" words entered.")
Create a class named Tile that represents Scrabble tiles. The instance variables should include a String named letter and an integer named value. Write a constructor that takes parameters named letter and value and initializes the instance variables. Write a method named printTile that takes a Tile object as a parameter and displays the instance variables (letter and value) in a reader-friendly format. Using a Driver class create a Tile object with the letter Z and the value 10, and then uses printTile to display the state of the object. Create getters and setters for each of the attributes.
Answer:
Here is the Tile class:
class Tile { //class name
// declare private data members of Tile class
private int value; //int type variable to hold the integer
private String letter; //String type variable to hold the letter
public void setValue(int value){ //mutator method to set the integer value
this.value = value; }
public void setLetter(String letter){ //mutator method to set the letter
this.letter = letter; }
public int getValue() //accessor method to access or get the value
{return value;} //returns the current integer value
public String getLetter() //accessor method to access or get the letter
{return letter;} //returns the current string value
public Tile(String letter, int value){ //constructor that takes parameters named letter and value
setValue(value); //uses setValue method to set the value of value field
setLetter(letter); } } //uses setValue method to set the value of letter field
/* you can also use the following two statements inside constructor to initializes the variables:
this.letter = letter;
this.value = value; */
Explanation:
Here is the driver class named Main:
public class Main{ //class name
public static void main(String[] args) { //start of main method
Tile tile = new Tile("Z", 10); //creates object of Tile class named tile and calls Tile constructor to initialize the instance variables
printTile(tile); } //calls printTile method by passing Tile object as a parameter
public static void printTile(Tile tile) { //method to displays the instance variables (letter and value) in a reader-friendly format
System.out.println("The tile " + tile.getLetter() + " has the score of " + tile.getValue()); } } //displays the string letter and integer value using getLetter() method to get the letter and getValue method to get the value

What is the value of the variable result after these lines of code are executed?
>>> a = 10
>>> b = 2
>>> c = 5
>>> result = a * b - a / c
The value of the variable is
.
Answer:
18
Explanation:
If you take the formula, and you substitute the values of the variables, it will be:
10 * 2 - 10 / 5
Then if you remember the order of math operations, it will be:
(10 * 2) - (10 / 5)
Which reduces to:
20 - 2 = 18
The value of the variable result is 18
The code is represented as follows:
Python code:a = 10
b = 2
c = 5
result = a * b - a / c
Code explanation;The variable a is initialise to 10The variable b is initialise to 2Lastly, the variable c is initialise to 5Then the arithmetic operation variable a multiplied by variable b minus variable a divided by variable c is stored in the variable "result".
Printing the variable "result" will give you 18.
Check the picture to see the result after running the code.

To follow the Principle of Least Privilege, Set-UID programs often permanently relinquish their root privileges if such privileges are not needed anymore. Moreover, sometimes, the program needs to hand over its control to the user; in this case, root privileges must be revoked. The setuid() system call can be used to revoke the privileges. According to the manual, "setuid() sets the effective user ID of the calling process. If the effective UID of the caller is root, the real UID and saved set-user-ID are also set". Therefore, if a Set-UID program with effective UID 0 calls setuid(n), the process will become a normal process, with all its UIDs being set to n. When revoking the privilege, one of the common mistakes is capability leaking. The process may have gained some privileged capabilities when it was still privileged; when the privileged is downgraded, if the program does not clean up those capabilities, they may still be accessible by the non-privileged process. In other words, although the effective user ID of the process becomes non-privileged, the process is still privileged because it possesses privileged capabilities. Compile the following program, change its owner to root, and make it a Set-UID program. Run the program as a normal user, and describe what you have observed. Will the file /etc/zzz be modified? Please explain your observation.

Answer:
text box
Explanation:
When it comes to collecting information such as the user's name, telephone number, address, etc., it is important to insert a text box into the form field. This can be done in several ways, such as giving the user the freedom to type her own response in the text box or making it "pre-filled." A text box with pre-filled value means that the user cannot type anything in the box because it has an existing value (default value). The text box may also give a "hint" in order to let the user know of possible values he can choose.

The input begins with an integer indicating the number of integers that follow. You can assume that the list will have at least 2 integers and less than 20 integers. Ex: If the input is: 5 10 5 3 21 2 the output is: 2 3 To achieve the above, first read the integers into an array. Hint: Make sure to initialize the second smallest and smallest integers properly. 265236.1527390
Answer:
Here is the C++ program:
#include <iostream> //to use input output function
#include <vector> //to use vectors
using namespace std; //to identify objects like cin cout
int main() { //start of main method
int size, number; //to store size of list and input numbers
cout<<"Enter list size: "; //prompts user to enter size of the list
cin >> size; //reads list size from user
vector<int> v; //creates a vector named v
for (int i = 0; i < size; ++i) { //iterates till the size of list reaches
cin >> number; //reads the input numbers
v.push_back(number); } //push number into a vector from the back
int num1 = v[0], num2 = v[1], current , temp; //num1 is set to the element at 0-th position of v and num2 is set to be on 1st index of v
if (num1 > num2) { //if num1 is is greater than num2
temp = num1; //assigns value of num1 to temp
num1 = num2; //assigns value of num2 to num1
num2 = temp; } //assigns value of temp to num2
for (int i = 2; i < size; ++i) { //iterates size times
current = v[i]; //set current to the i-th index of v
if (current < num1) { //if current is less than num1
num2 = num1; //assigns value of num1 to num2
num1 = current; } //assigns value of current to num1
else if(current < num2) { //if value of current is less than num2
num2 = current; } } //assigns value of current to num2
cout<<num1<< " "<<num2<< endl; } //dispalys num1 and num2 i.e. two smallest integers in ascending order
Explanation:
I will explain the program with an example.
Lets say the list size is 4 and numbers are 1 2 3 4
for (int i = 0; i < size; ++i)
This loop reads each number (1,2,3,4) and adds that number to the vector v which is the sequence container. The method push_back is used which inserts each number into the vector at the end, after the current last number and the vector size is increased by 1.
Next num1 = v[0] becomes num1 = 1
and num2 = v[1] becomes num1 = 2
if (num1 > num2) this condition is false so program moves to the statement:
for (int i = 2; i < size; ++i)
current = v[i]; becomes current = v[2]; which is current = 3
if (current < num1) is false so program moves to :
else if(current < num2) this is also false.
So the program moves to the statement:
cout<<num1<< " "<<num2<< endl;
which prints these two numbers 1 and 2 on output screen as the two smallest integers in the list in ascending order. Hence the output of the program is:
1 2
The screenshot of output of the program is attached.

What is python?Python is a popular computer programming language used to create software and websites, automate processes, and analyze data. Python is a general-purpose language, which means it may be used to make many various types of applications and isn't tailored for any particular issues.
A function is a section of code that only executes when called. You can supply parameters—data—to a function. The main() function in Python serves as the point at which any software application is executed.
Since the program only runs when it is executed directly, and not if it is imported as a module, the execution of the program can only begin when the main() function is declared in Python.

Explanation:
The answers are straight forward.
However, I'll give a general hint in answering questions like this.
In C, variable declaration is done by:
data-type variable-name;
To declare and initialise the variable, you do;
data-type variable-name = value;
So, for questions that requires that we declare and initialise a variable, we make use of the above syntax..
Take (a) for instance:
int x = 25;
int y = 18;
Same syntax can be applied to (b), (d), (e), (h) & (I)
For question (c);
This can be done in two ways;
x = x + 5;
Or
x+=5;
Both will give the same result.
For question (f):
We start by initialise a temporary variable that stores x.
Then we store the value of x in y.
Then we store the content of the temporary variable to y.
This swaps the values of x and y
For question (g):
When printing a double variable in C, we make use of '\f' as a string format
For question (j):
The round function is used to round up a double variable to integer.
