In other words, the void data type is used when we don't want to return any value to the calling function. Furthermore, it is used with the main() function to return nothing and can be used with user-defined and predefined functions in C programming.

The `int` return type indicates that the function returns an integer value, typically used to convey the exit status of the program to the operating system. The `void` keyword indicates that the function does not return any value. Using `void main()` is a common mistake or misunderstanding, and it may not be supported by all compilers. read less

In the C programming language, void main() is not a valid signature for the main function. The correct signature for the main() function in C is either int main() or int main(int argc, char *argv[]).

The main() function serves as the entry point of a C program. It is where the execution of the program begins. The int return type indicates that the main() function should return an integer value to the operating system upon completion. By convention, a return value of 0 typically indicates successful execution, while a non-zero value indicates an error or abnormal termination.

Here's a brief explanation of the correct signatures:

  1. int main(): This signature is used when your program doesn't require any command-line arguments. The absence of parameters means that the program doesn't receive any arguments from the command line.

  2. int main(int argc, char *argv[]): This signature is used when your program needs to accept command-line arguments. The argc parameter represents the count of command-line arguments passed to the program, and argv[] is an array of strings containing those arguments.
