c++ code
Sure! Here is an example of C++ code with explanations for each step:
#include <iostream>
int main() {
// Step 1: Declare variables
int num1, num2, sum;
// Step 2: Read input from user
std::cout << "Enter two numbers: ";
std::cin >> num1 >> num2;
// Step 3: Perform addition
sum = num1 + num2;
// Step 4: Display the result
std::cout << "The sum is: " << sum;
// Step 5: End the program
return 0;
}
Step 1: Declare variables
In this step, we declare three variables: num1
, num2
, and sum
. These variables will be used to store the numbers entered by the user and the result of the addition.
Step 2: Read input from user
Here, we use the std::cin
object to read input from the user. The std::cout
object is used to display the prompt message asking the user to enter two numbers. The >>
operator is used to extract the input values and store them in the variables num1
and num2
.
Step 3: Perform addition
In this step, we add the values of num1
and num2
and store the result in the variable sum
using the +
operator.
Step 4: Display the result
Here, we use the std::cout
object to display the result of the addition. The <<
operator is used to insert the value of sum
into the output stream.
Step 5: End the program
Finally, we return 0
from the main
function to indicate successful execution of the program. This is a convention in C++ to indicate that the program has completed without any errors.
