Listing 4 Avoiding a compiler error

(a). /* This code will cause a compile error */
void main(void)
{
	int i = 10;
 	printf("i: %d\n", i);
	int j = 100;  /* This statement will cause a compiler error since
                     	    it was not declared at the top of the function. */
	printf("j: %d\n", j);
}

(b). /* whereas this code will not */
void main(void)
{
	int i = 10;
	printf("i: %d\n", i);
	{
		int j = 100;            /* This statement is fine since it is akin
				to defining a local function within the function.  */
		printf("j: %d\n", j);
	}
