#include "stdio.h"  
int main()
{
	int a;
	int b = 4;
	int c = 8;
	int d = 2;
	int e = 4;
	int f = 2;

	a = b + c / d + e * f;                /* result without parentheses */
printf("The value of a is = %d \n", a);

	a = (b + c) / d + e * f;              /* result with  parentheses */
printf("The value of a is = %d \n", a);

	a = b + c / ((d + e) * f);      /* another result with parentheses */
printf("The value of a is = %d \n", a);

	return 0;
} 

Output:

The value of a is = 16
The value of a is = 14
The value of a is = 4
