=> The main function serves as the starting point for
program execution.

=> It usually controls program execution by directing the
calls to other functions in the program.

=> A program usually stops executing at the end of main,
although it can terminate at other points in the program
for a variety of reasons.
=> At times, perhaps when a certain error is detected, you
may want to force the termination of a program. To do so,
use the exit function. See the Run-Time Library Reference
for information on and an example using the exit function.

so that
main() is a user defined function. it is the entry point of
any program.
