int main(void)

As an AI language model, I can provide an explanation of what the "int main(void)" code means in programming.

In C and C++ programming, "int main(void)" is the entry point function for a program. It is where the program starts executing. The "int" specifies that the function will return an integer value to the operating system when the program exits. The "void" inside the parentheses means that the function takes no arguments.

Here's an example of how it may be used in a program:

#include <stdio.h>

int main(void) {
    printf("Hello, World!\n");
    return 0;
}

In this example program, the function "main" simply prints the string "Hello, World!" to the screen using the "printf" function, then returns the integer value 0 to the operating system. This signals that the program has completed successfully.
