Answer 
The main function is an integral part of the programming languages such as C, C++, and Java. The main function in C is the entry point of a program where the execution of a program starts. It is a user-defined function that is mandatory for the execution of a program because when a C program is executed, the operating system starts executing the statements in the main() function.
Syntax of C main() Function
return_type main() {
// Statement 1;
// Statement 2;
// and so on..
return;
}
We can write the main function in many ways in C language as follows:
int main(){} or int main(void){}
main(){} or void main(){} or main(void){} or void main(void){}
