Its a user defined function. How can it be inbuilt

start the program.

Answer / govind

=> 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.

Answer / eklavya sharma

main is a kind of function which is a user defined function for the C compiler developer and it is built in or predifined function to the users using that compiler. The prototype has already been defined in the compiler itself we the users can't change the meaning of that unless or until we write our own compiler.

Answer / rajen kumar

if main() is user define...then why not...we can't change
it's name ??

Answer / ekta

1: Main is not a user defined function because user defined
functions can be given be given their own names .We can not
give a new name to main.

2:Main is not an inbuilt function because every inbuilt
function is defined in a specific library .But main has not
been defined in any library.it even works without libraries.

So finally main is just a convention to start a program.
Every language like java,c++,c all start their execution
from main.All programs need a starting point.
