Output of the following?

#include<stdio.h>
int main()
{
   int a,b,c,d,e,f;
   a=1;b=4;c=2;d=3;e=5;f=3;
   printf("%d",1-a+b*c%d/(e-f));
   return 0;
}

Choices:

a) compile error     b) execution stops     c) 0     d). 1     e) -3      f) 2    g)none

For explanation visit "click here for program" link below.

step.1: 1-a+b*c%d/(5-3)     ( brackets have highest priority among all)

step.2: 1-a+b*c%d/2

step.3: 1-a+4*2%d/2          ( *,/,% have same priority and have left to right associativity )

step.4: 1-a+8%3/2

step.5: 1-a+2/2

step.6: 1-a+1

step.7: 1-1+1                     ( +, - have same priority and have left to right associativity)

step.8: 0+1

step.9: 1

Now the expression returns its result. so 1 is printed
