To understand this you just need to find out why divided by zero is undefined.

Divide by Zero Errors

It is a common problem that at the time of dividing any number, programmers do not check if a divisor is zero and finally it creates a runtime error.

The code below fixes this by checking if the divisor is zero before dividing −

 #include <stdio.h>
 #include <stdlib.h>

main() {

   int dividend = 20;
   int divisor = 0;
   int quotient;

   if( divisor == 0){
      fprintf(stderr, "Division by zero! Exiting...\n");
      exit(-1);
   }

   quotient = dividend / divisor;
   fprintf(stderr, "Value of quotient : %d\n", quotient );

   exit(0);
}

When the above code is compiled and executed, it produces the following result −

Division by zero! Exiting...

Hope you understand the concept of Dividing with zero Error in C
