Modulus on Negative Numbers

What will be the output of the following C program?

#include <stdio.h> 
int main() 
{ 
   int a = 3, b = -8, c = 2; 
   printf("%d", a % b / c); 
   return 0; 
} 

Output

% and / have same precedence and left to right associativity. So % is performed first which results in 3 and / is performed next resulting in 1. The emphasis is, sign of left operand is appended to result in case of modulus operator in C.

#include <stdio.h> 
int main() 
{ 
   // a positive and b negative. 
   int a = 3, b = -8; 
   printf("%d", a % b); 
   return 0; 
} 

Output

#include <stdio.h> 
int main() 
{ 
   // a negative and b positive 
   int a = -3, b = 8; 
   printf("%d", a % b); 
   return 0; 
} 

/div>

Output

-3

#include <stdio.h> 
int main() 
{ 
   // a and b both negative 
   int a = -3, b = -8; 
   printf("%d", a % b); 
   return 0; 
} 

Output

-3
