The main function is the entry point of a C program. It is where the program starts executing. The main function must have a return type of int and must take no arguments. The following are two valid ways to declare the main function in C:

“`c
void main() {
}

void Main() {
}
“`

The only difference between the two declarations is the capitalization of the first letter of the function name. In C, function names are case-sensitive, so both declarations are valid.

The main function is typically used to initialize variables, call other functions, and print output to the console. The following is an example of a simple C program that prints
