Here is an explanation for each step in the C++ program:

Step 1: Include the necessary header files In C++, we typically include header files at the beginning of a program to access various functions and features. These files contain pre-defined functions and definitions that we can use in our program.

Step 2: Define the main function The main function is the entry point of a C++ program. It is where the execution of the program begins. In this step, we define the main function using the int keyword, which indicates that the function will return an integer value.

Step 3: Declare variables Variables are used to store data in a program. In this step, we declare any variables that we will be using in our program. The declaration includes the data type of the variable and its name.

Step 4: Prompt the user for input In this step, we use the cout object to display a prompt on the console, asking the user to enter a value. The << operator is used to output the prompt.

Step 5: Read user input In this step, we use the cin object to read input from the user. The >> operator is used to assign the user's input to a variable. The user's input can then be used in the program.

Step 6: Perform calculations or operations This step involves performing any necessary calculations or operations using the variables and user input. This can include mathematical calculations, string manipulations, or any other operations required by the program.

Step 7: Display the result In this step, we use the cout object to display the result of the calculations or operations to the user. The << operator is used to output the result.

Step 8: End the program To end the program, we use the return statement in the main function. The return statement is followed by a value, which is returned to the operating system. Typically, we use the value 0 to indicate successful execution of the program.

Step 9: Terminate the program At the end of the program, we terminate it by closing any open files, releasing memory, and performing any necessary cleanup. This step ensures that the program ends gracefully and any resources used by the program are properly released.
