Sure! Here is a response without any personal words or sentences at the beginning or end:
To give explanations for each step in C++, let's consider the following example:
#include <iostream>
int main() {
int num1, num2, sum;
// Step 1: Prompt the user to enter two numbers
std::cout << "Enter two numbers: ";
std::cin >> num1 >> num2;
// Step 2: Calculate the sum of the two numbers
sum = num1 + num2;
// Step 3: Display the sum
std::cout << "The sum is: " << sum << std::endl;
return 0;
}
Step 1: Prompt the user to enter two numbers
In this step, we use the std::cout
object to display the message "Enter two numbers: " to the user. The <<
operator is used to insert the string into the output stream. Then, we use the std::cin
object along with the >>
operator to read two integer values from the user and store them in the variables num1
and num2
.
Step 2: Calculate the sum of the two numbers
In this step, we declare a variable sum
of type int
to store the sum of the two numbers. We use the +
operator to add num1
and num2
and assign the result to the sum
variable.
Step 3: Display the sum
In this step, we use the std::cout
object to display the message "The sum is: " to the user. We use the <<
operator to insert the string into the output stream, and then we use the <<
operator again to insert the value of sum
into the output stream. Finally, we use std::endl
to insert a newline character into the output stream to display the result on a new line.
Step 4: Return 0
In this step, we use the return
statement to exit the main
function and return the value 0 to the operating system. This value indicates that the program executed successfully.
