int CountCharacters(char userChar, const string inputstr){
int k = 0;
int iter = 0;
for (iter = 0; iter < inputstr.size(); iter++){
if (inputstr[iter] == userChar){
++k; }}
return k;}
int main(){
string str;
char userChar[1];
cout<<"Char: "; cin>>userChar;
cin.ignore();
cout<<"String: "; getline(cin, str);
cout<<CountCharacters(userChar[0],str);
return 0;}
Explanation:
Written in C++:
The function is defined here:
int CountCharacters(char userChar, const string inputstr){
This initializes a count variable k to 0
int k = 0;
This initializes an iterating variable iter to 0
int iter = 0;
This iterates through the characters of the string being passed to the function
for (iter = 0; iter < inputstr.size(); iter++){
This checks for matching characters
if (inputstr[iter] == userChar){
If found, k is incremented by 1
++k; }}
This returns the total count
return k;}
The main begins here
int main(){
This declares a string variable
string str;
This declares a character variable
char userChar[1];
This gets input for the character variable
cout<<"Char: "; cin>>userChar;
This lets the user get another input
cin.ignore();
This gets input for the string variable
cout<<"String: "; getline(cin, str);
This calls the function and return the count of character in the string
cout<<CountCharacters(userChar[0],str);
Ram and Hari can finish a piece of work in 6 days and 12 days respectively in how many days will they finish it working together
Answer:
4 days
Explanation:
Given - Ram and Hari can finish a piece of work in 6 days and 12 days
respectively.
To find - In how many days will they finish it working together
Proof -
As given,
Ram and Hari can finish a piece of work in 6 days and 12 days respectively.
⇒1 day work of Ram done in = [tex]\frac{1}{6}[/tex]
1 day work of Hari done in = [tex]\frac{1}{12}[/tex]
If they work together,
1 day work of both together done in = [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{12}[/tex] = [tex]\frac{2 + 1}{12} = \frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
As we know Work is inversely proportional to efficiency
And efficiency = Person's 1 day work
As we have ,
1 day work of both together done in = [tex]\frac{1}{4}[/tex]
⇒ Total work done in 4 days if they work together.

Can hardware work without software? Why?
Answer:
No
Explanation:
Short answer:
In contrast to software, hardware is a physical entity. Hardware and software are interconnected, without software, the hardware of a computer would have no function. However, without the creation of hardware to perform tasks directed by software via the central processing unit, software would be useless.
Extended answer:
hardware cannot function without software. Without software, hardware is just a piece of silicon with some pins jutting out of it.
Softwares are sets of instructions, somewhat like a soul is for humans, made to tell the hardware what to do.
Many have a misconception that hardware you buy such as a graphics card or a motherboard does not come with software. In fact, it does. It is not however, visible to mosts users as its job is to make the piece of silicon function as a computer.
The RAM is one such hardware that does not come with software and it needs to be plugged to a motherboard which has a software to function.
No, hardware cannot work without software.
So, in order for a computer or electronic device to work, it requires both hardware and software working together.
Here,
Hardware refers to the physical components of a computer or electronic device, such as the processor, memory, hard drive, and motherboard. Software, on the other hand, consists of the programs and instructions that tell the hardware what tasks to perform.
Hardware and software are interdependent. Hardware needs software to function because without software, hardware does not have any instructions to execute.

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should NOT be added to the list). These values entered by the user are added to a list we call 'initial_list'. Then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. Finally, inside main(), print out all of the values in the new list.
Answer:
def create_3_copies(initial_list):
another_list = []
for i in range(3):
for x in initial_list:
another_list.append(x)
return another_list
initial_list = []
while True:
value = input("Enter a value: ")
if value == "exit":
break
initial_list.append(value)
for x in create_3_copies(initial_list):
print(x, end=" ")
Explanation:
Create a function that takes initial_list as parameter. Inside the function:
Create an empty list called another_list
Create a nested for loop. The outer loop iterates 3 times (Since we need to add every value 3 times). The inner loop iterates through the another_list and adds each value to the another_list.
When the loops are done, return the another_list
In the main:
Create an empty list named initial_list
Create an indefinite while loop. Inside the loop, ask the user to enter a value. If the value equals "exit", stop the loop. Otherwise, add the value to the initial_list
Create another for loop that calls the function we created passing the initial list as a parameter and iterates through the values that it returns. Inside the loop, print each value

Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Hint: Use the to_string() function to convert numerical data to a string.
Answer:
In C++:
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main(){
string lname, fname,stringnum; int num; string login, pwd;
cout<<"Last Name: "; cin>>lname;
cout<<"First Name: "; cin>>fname;
cout<<"Four-digit integer: "; cin>>num;
stringnum = to_string(num).substr(0,4);
stringstream geek(stringnum); geek>>num;
num = num%100;
pwd = to_string(num);
if(lname.length()<5){ login = lname+fname.substr(0,1); }
else{ login = lname.substr(0,5)+fname.substr(0,1); }
cout<<"Login Name: "<<login<<endl;
cout<<"Password: "<<pwd<<endl;
return 0;
}
Explanation:
This declares all necessary variables
string lname, fname,stringnum; int num; string login, pwd;
This prompts the user for last name
cout<<"Last Name: "; cin>>lname;
This prompts the user for first name
cout<<"First Name: "; cin>>fname;
This prompts the user for a four digit integer
cout<<"Four-digit integer: "; cin>>num;
This converts the input number to string and gets only the first four integer
stringnum = to_string(num).substr(0,4);
This converts the string back to an integer
stringstream geek(stringnum); geek>>num;
This gets the last two of the four digit integer
num = num%100;
This gets the password of the user
pwd = to_string(num);
This gets the login name of the user.
This is executed if the length of the first name is less than 5
if(lname.length()<5){ login = lname+fname.substr(0,1); }
This is executed if otherwise
else{ login = lname.substr(0,5)+fname.substr(0,1); }
This prints the login name
cout<<"Login Name: "<<login<<endl;
This prints the password
cout<<"Password: "<<pwd<<endl;

(4 points.) Write an algorithm (i.e., step-by-step instructions) via which someone could walk or drive from some origin to some destination, perhaps a path that you yourself tend to travel. Take care to specify what the origin and destination that you have in mind. And take care to use loops and conditions as needed, particularly if there might be obstacles (e.g., red lines). Assume that your algorithm will be executed by a robot (or lost friend) who will follow your directions precisely, so avoid ALL ambiguity!
Answer:
The algorithm is as follows :
1. Record Current Position, Final Destination
2. While Current Position is not Final Destination, repeat the following:
2.1 If destination location is up then:
2.1.1 If an obstacle is directly above you then:
2.1.1.1 Look for alternate position (left, right, down)
2.1.1.2 If alternate position is found then
2.1.1.2.1 Move there
2.1.1.2.2 Record Current Position
2.1.1.3 If no alternate position is found then
2.1.1.3.1 Call for help
2.1.1.3.2 End
2.1.2 If no obstacle is directly above you then:
2.1.2.1 Move up
2.1.2.1 Record Current Position
2.2 If destination location is down then:
2.2.1 If an obstacle is directly below you then:
2.2.1.1 Look for alternate position (left, right, up)
2.2.1.2 If alternate position is found then
2.1.1.2.1 Move there
2.2.1.2.2 Record Current Position
2.2.1.3 If no alternate position is found then
2.2.1.3.1 Call for help
2.2.1.3.2 End
2.2.2 If no obstacle is directly below you then:
2.2.2.1 Move down
2.1.2.1 Record Current Position
2.3 If destination location is right then:
2.3.1 If an obstacle is directly by your right then:
2.3.1.1 Look for alternate position (down, up, left)
2.3.1.2 If alternate position is found then
2.3.1.2.1 Move there
2.3.1.2.2 Record Current Position
2.3.1.3 If no alternate position is found then
2.3.1.3.1 Call for help
2.3.1.3.2 End
2.3.2 If no obstacle is directly by your right then:
2.3.2.1 Move right
2.3.2.1 Record Current Position
2.4 If destination location is left then:
2.4.1 If an obstacle is directly by your left then:
2.4.1.1 Look for alternate position (down, up, right)
2.4.1.2 If alternate position is found then
2.4.1.2.1 Move there
2.4.1.2.2 Record Current Position
2.4.1.3 If no alternate position is found then
2.4.1.3.1 Call for help
2.4.1.3.2 End
2.4.2 If no obstacle is directly by your left then:
2.4.2.1 Move left
2.4.2.1 Record Current Position
Explanation:
The algorithm is straight forward.
All it does is to check for available position and move into the position if there is any available.
It keeps checking and moving until an obstacle prevents it from moving.

Why wouldn't a game using just run-length encodings be challenging?
A set of run-length encodings would not be a challenge because of the predictability of the challenges.
We can arrive at this answer because:
Run-length encodings allow long strings of many repetitive values to be represented as an original string.This type of encoding is very efficient on data that is replicated very frequently, emits simple images, and has an easy interface to analyze and manipulate.When this is approached within a game, it promotes simple, repetitive, and predictable stages, where the player can easily know where the challenges will present themselves and how to overcome them, in addition to getting software that is simple to handle.

In 2019, the tuition for a full time student is $7,180 per semester. The tuition will be going up for the next 7 years at a rate of 3.5% per year. Write your program using a loop that displays the projected semester tuition for the next 7 years. You may NOT hard code each years tuition into your program. Your program should calculate the tuition for each year given the starting tuition in 2019 ($7, 180) and the rate of increase (3.5%). You should then display the actual year (2020, 2021, through 2026) and the tuition amount per semester for that year
Answer:
In Python:
tuition = 7180
year = 2019
rate = 0.035
for i in range(2019,2027):
print(str(year)+": "+str(round(tuition,2)))
tuition = tuition * (1 + rate)
year = year + 1
Explanation:
This initializes the tuition to 7180
tuition = 7180
This initializes the year to 2019
year = 2019
This initializes the rate to 3.5%
rate = 0.035
This iterates through years 2019 to 2026
for i in range(2019,2027):
This prints the year and tuition
print(str(year)+": "+str(round(tuition,2)))
This calculates the tuition
tuition = tuition * (1 + rate)
This increments year by 1
year = year + 1

cout <<"First-time divide: "<<userNum / divNum<<endl;//divide value First time
cout <<"Second-time divide: " << userNum / divNum/divNum<<endl; //divide value Second time
cout<<"Third-time divide: "<< userNum /divNum/divNum/divNum<<endl;//divide value Third time
return 0;
}
Output:
2000
2
First-time divide: 1000
Second-time divide: 500
