#include <stdio.h>



main() {



   int a = 21;

   int b = 10;

   int c ;



   c = a + b;

   printf("Line 1 - Value of c is %d\n", c );



   c = a - b;

   printf("Line 2 - Value of c is %d\n", c );



   c = a * b;

   printf("Line 3 - Value of c is %d\n", c );



   c = a / b;

   printf("Line 4 - Value of c is %d\n", c );



   c = a % b;

   printf("Line 5 - Value of c is %d\n", c );



   c = a++;

   printf("Line 6 - Value of c is %d\n", c );



   c = a--;

   printf("Line 7 - Value of c is %d\n", c );
