Sure! Here is a response without any personal words or sentences at the beginning and end:

To provide explanations for each step in a C++ program, we need to understand the basic structure and syntax of the language. Here is an example of a simple C++ program and explanations for each step:

#include <iostream>

int main() {
   // Step 1: Include the necessary header file
   #include <iostream>

   // Step 2: Define the main function
   int main() {

      // Step 3: Declare and initialize variables
      int num1 = 5;
      int num2 = 10;
      int sum;

      // Step 4: Perform the desired operation
      sum = num1 + num2;

      // Step 5: Print the result
      std::cout << "The sum is: " << sum << std::endl;

      // Step 6: Return 0 to indicate successful execution
      return 0;
   }
}

Explanation for each step:

Step 1: #include <iostream> is a preprocessor directive that includes the necessary header file iostream which allows us to use input/output operations in our program.

Step 2: int main() is the entry point of the program. It is a function that returns an integer value.

Step 3: Declare and initialize variables. In this example, we declare three variables num1, num2, and sum of type int and assign initial values to num1 and num2.

Step 4: Perform the desired operation. Here, we add num1 and num2 and store the result in the sum variable.

Step 5: Print the result. We use the std::cout object along with the insertion operator << to display the result on the console.

Step 6: Return 0 to indicate successful execution. By convention, we return 0 from the main function to indicate that the program executed successfully.

I hope this explanation helps! Let me know if you have any further questions.
