Program Plan Intro

Function:

One of the building blocks of C++ program is functions; it contains a group of statements which are used to perform a specific task and the executable segments for a program.

• The function “main()” is the most important function in a program, because the “main()” function is the starting point of the program.
• The main advantage of using a function is that it reuses and reduces the code size of the program, because a function can be called for a multiple numbers of times.
