Step 1: Include the necessary header files Explanation: In C++, header files contain declarations of functions, classes, and variables that are used in the program. They provide the necessary information to the compiler about the different components being used. Including the necessary header files at the beginning of the program ensures that the compiler knows about the functions and classes being used in the program.

Step 2: Define the main function Explanation: The main function is the entry point of a C++ program. It is the starting point of execution and contains the code that will be executed when the program runs. The main function must be defined in every C++ program.

Step 3: Declare and initialize variables Explanation: Variables are used to store data in a C++ program. Before using a variable, it must be declared, which specifies its data type. Initialization refers to assigning an initial value to a variable when it is declared. This step ensures that the variables used in the program are properly declared and initialized.

Step 4: Perform necessary calculations or operations Explanation: This step involves performing the required calculations or operations using the variables declared and initialized in the previous step. The specific calculations or operations will depend on the requirements of the program.

Step 5: Display the output Explanation: The final step involves displaying the output of the program. This could be done by using the cout statement, which is used to output data to the console. The output could be the result of the calculations performed in the previous step or any other relevant information.

Step 6: End the main function Explanation: After the necessary calculations and output have been performed, the main function can be ended. This is done by using the return statement, which terminates the function and returns a value to the operating system.

Step 7: End the program Explanation: Once the main function has ended, the program can be terminated. This is usually done automatically by the operating system.
