Answer 1

#include <stdio.h>

void foo() {

void boo(void) {
}

int main()
{
    foo();
    foo(1);
    foo(2, 'B');
    foo(3, "ABC");
    foo(4, 'x', "pro");
    foo("printf(\"for\");");

    int x = 1889;
    foo(x);
    char ch = 'z';
    foo(x, ch);

    boo();
    boo(1); // Warning	C4087 'boo': declared with 'void' parameter list main.c	19

    return 0;
