void f()
{
printf("HELLO");
}
int main() {
int x;
x=2;
printf("%d\t%d",x,f);
return 0;
}

Answer 1

You will faced with a warning because first argument in printf() declare two integer values but third argument is not an integer value.
The output of the f( ) function is void and does not return any thing.
