    main() is the user defined function.

   main() is the first function in the program which gets called when the         program   executes.The startup code contains runmain() function which calls main() function.we can't chage the name of the main() function.

It is user defined function, because function body is given by the user, What you will do with main function if we wont write anything inside main function.

This is a default function, compiler enters from here and also exit from here. If you have declared various functions in program then you have to call it inside the main, otherwise they cannot be executed.
