Answer: B I took the test

Explanation:

The function that will add a name to a list of baseball players in Python is main(). The correct option is b.

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.

Therefore, the correct option is b, main().

Answer:

Here is the JAVA program:

import java.util.Scanner;  //to accept input from user

public class Main{  //class name

public static void main(String[] args){ //start of main function

String sentence;  //to store the input sentence

int i, length;  //declare variables

int count[] = new int[256];  //creates a counter array

  Scanner input = new Scanner(System.in);  //creates Scanner class object to accept input from user

       System.out.println("Enter a sentence: ");  //prompts user to enter a sentence

       sentence = input.nextLine();  //scans and reads the entire sentence string from user

   String[] words = sentence.split("\\s+");  //splits the sentence into an array with separator as one or more white spaces and stores this array in words

   System.out.println("Number of words: " + words.length);  //display the number of words in sentence by using length which returns the length of the words array

     sentence = sentence.toLowerCase();  // converts the sentence into lower case to ignore case sensitivity

     sentence = sentence.replaceAll("\\s+","");  //removes the empty spaces from sentence

     length = sentence.length();  //stores the length of the sentence string into length variable

       for (i = 0; i < length; i++) {  //iterates through the length of the sentence

           count[(int) sentence.charAt(i)]++;        }  //counts occurrence of each alphabet in the sentence and stores it in count array

       for (i = 0; i < 256; i++) {  displays occurrence of alphabet in sentence

           if (count[i] != 0) {  //if count array is not empty

               System.out.println((char) i + "-" + count[i]);  }}}}

//prints each alphabet and its count

Explanation:

The program prompts the user to enter a sentence. Suppose the user enters "We won" so

sentence = "We won"

Now this sentence splits into an array with white space as separator and stored in words array. So words array has two words of sentence now i.e. "We" and "won"

Next words.length is used to return the length of words array. So length of words array is 2 hence

number of words = 2

Next the sentence is converted to lower case and spaces are removes so sentence becomes:

wewon

sentence.length() returns the length of sentence which is 5.

Next the for loop is used. At each iteration of this loop occurrence each character of sentence is added to the count[] array. charAt() is used to return a character at each index position of string. So the frequency of every character is counted and stored in count array.

Next is a for loop that is used to display each alphabet in the sentence along with its frequency in alphabetic order.

Hence the entire program gives the output:

Number of words: 2                                                                                                             e-1                                                                                                                            n-1                                                                                                                            o-1                                                                                                                            w-2

The screenshot of the output of example given in the question is attached.

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.")

Answer:

def check_password(password):

   is_short = False

   has_uppercase = False

   has_lowercase = False

   has_digit = False

   if len(password) < 8:

       is_short = True

   for p in password:

       if p.isupper():

           has_uppercase = True

       if p.islower():

           has_lowercase = True

       if p.isdigit():

           has_digit = True

   if is_short == False and has_uppercase and has_uppercase and has_digit:

       return True

   else:

       return False

while True:

   password = input("Enter your password: ")

   password2 = input("Enter your password again: ")

   if password == password2 and check_password(password):

       break

Explanation:

Create a function named check_password that takes one parameter, password

Inside the function:

Initialize the is_short, has_uppercase, has_lowercase, and has_digit as False. These variables will be used to check each situation

Check the length of the password using len() method. If it is smaller than 8, set is_short as True

Create a for loop that iterates through password. Check each character. If a character is uppercase, set the has_uppercase as True (use isupper() function). If a character is lowercase, set the has_lowercase as True (use islower() function). If a character is a digit, set the has_digit as True (use isdigit() function).

When the loop is done, check the value of is_short, has_uppercase, has_lowercase, and has_digit. If is_short is False and other values are True, return True. Otherwise, return False

Create an indefinite while loop, that asks the user to enter password twice. Check the entered passwords. If they are equal and the check_password function returns True, stop the loop. This implies that both passwords are same and password is valid.

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.

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.

Answer:

A- text box

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:

a = 10

b = 2

c = 5

result = a * b - a / c

Then 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.

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
