Answer:
Complete C++ code along with output and comments for explanation is provided below.
C++ Code with Explanation:
#include <iostream>
using namespace std;
// implement a function named print_sum which takes three input numbers of type int and returns the sum of these three numbers.
int print_sum(int num1, int num2, int num3)
{
// initialize the variable to hold the value of sum
int sum;
// add the three numbers and store the result in the variable sum
sum = num1 + num2 + num3;
// print the sum of three numbers
cout<<"The sum of three numbers is: "<<sum<<endl;
}
// driver code starts here
int main()
{
// initialize the three input numbers
int x,y,z;
// get the three numbers from the user
cout << "Please enter number 1: "<<endl;
cin >> x;
cout << "Please enter number 2: "<<endl;
cin >> y;
cout << "Please enter number 3: "<<endl;
cin >> z;
// call the function print_sum to calculate the sum
print_sum(x,y,z);
return 0;
}
Output:
Please enter number 1:
24
Please enter number 2:
13
Please enter number 3:
7
The sum of three numbers is: 44

The program is an illustration of conditional statements.
Conditional statements are used to execute instructions, if and only if certain <em>condition or conditions </em>are met.
Take for instance: <em>If b = 5, print "ab"</em>
The above print statement will only be executed, if the <em>value of b is 5</em>
The paper-rock-scissor program in Python where comments are used to explain each line is as follows,
#This imports the random module
import random
#This is used to control the repetition of the game
playagain ="T"
#The following is repeated until the user chooses not to play again
while(playagain == "T"):
#This generates a random choice for the computer
computer = random.choice(['Rock', 'Paper', 'Scissors'])
#This gets input for the player
player = input('Choose: ')
#If the player and computer choose the selection
if player == computer:
#Then, it's a tie
print('A tie - Both players chose '+player)
#If the player wins
elif (player.lower() == "Rock".lower() and computer.lower() == "Scissors".lower()) or (player.lower() == "Paper".lower() and computer.lower() == "Rock".lower()) or (player == "Scissors" and computer.lower() == "Paper".lower()):
#This prints "player won" and the reason
print('Player won! '+player +' beats '+computer)
#If otherwise,
else:
#This prints "computer won" and the reason
print('Computer won! '+computer+' beats '+player)
#This asks if the player wants to play again
playagain = input("Play again? T/F: ")
At the end of each round,
- The program displays the winner
- Or prints a tie, if there's a tie
