Sure! Here is an explanation of each step in the C++ program:

1. Start by including the necessary header files. In C++, you typically include the "iostream" header file to enable input and output operations. For example:

include

1. Declare the main function. In C++, every program starts executing from the main function. The main function has a return type of "int" and takes no parameters. For example:

int main() {

1. Declare variables. In C++, you need to declare variables before using them. You can declare variables of different types, such as int, float, char, etc. For example:

int age; float height; char grade;

1. Prompt the user for input. You can use the "cout" object to display a message to the user, and the "cin" object to read input from the user. For example:

std::cout << "Enter your age: "; std::cin >> age;

1. Perform calculations or operations. You can use arithmetic operators like +, -, *, /, etc., to perform calculations. For example:

height = age * 0.5;

1. Display output. You can use the "cout" object to display the calculated results or any other messages. For example:

std::cout << "Your height is: " << height << std::endl;

1. End the main function. In C++, you use the "return" statement to indicate the end of the main function. The return statement can also return an integer value to the operating system, indicating the status of the program execution. For example:

return 0;

1. End the program. This is where the program execution ends. For example:

}
