What is the parameter of "int main()" in C ? Does this even take any?

Question

Hey, could anyone tell me how this parameter works? Is it possible to link two int main() file or sub(just another page) program?

Answer 1

These are passed to a C program through two arguments to the main() function. The parameters are called argc and argv. These parameters are optional and are not used when no command-line arguments are being used. The argc parameter holds the number of arguments on the command-line and is an integer.

Answer 2

main is entry function and start point for every program. You can have more than one main function, that is knowing as function overloading.
