          Task B: Finding Errors in a Simple Program

As compiler warnings are an essential aid when programming in C and C++, to demonstrate this, the program below contains a subtle error:

#include <stdio.h>
int main(void)
{
  printf("Two plus two is %f\n", 4.0);
  return 0;
}

This warning is not obvious at first sight but can be detected by the compiler if the warning option -Wall has been enabled.

6. Compiling the program above, 'warning.c', with the warning option -Wall included, what message is produced by the compiler? â€“ Please include your output here.
