#include "stdio.h"
main()
{
	int i=1,j=2;
	switch(i)
	{
		case 1:  printf("GOOD");
			break;
		case j:  printf("BAD");
		   break;
	}
}

Answer:
Compiler Error: Constant expression required in function main.

Explanation:
The case statement can have only constant expressions (this implies that we cannot use variable names directly so an error).

Note:
Enumerated types can be used in case statements.
