Thread: Arithmetic exception

Hi The following is my code I am getting Arithmetic exception in gcd function at rem=a%b can anyone help me finf why? how do I fix it?

Code:

#include "Pionare.h"

int main(int argc, char * argv[]) {
int  n=atoi(argv[1]);// convert string to integer
  Pionare Pionare1(n);
   return 0;
}

Pionare::Pionare(int n)
{
cout << "am in cons";
  this->n=n;
cout << "n is" << n;
 Findab();
}

void Pionare::Findab(){
cout << "n is" << n;
  for(b=1;b<=n;b++){
    for(a=1;a<= b*1.414;a++){
cout << "am here";
     if(Gcd(a,b)==1){

	p=a*a*a*a-6*a*a*b*b+b*b*b*b;

	q=(a*a+b*b)*(a*a+b*b);
	B=-54*(p*p*p*p*p*p-33*p*p*p*p*q*q-33*p*p*q*q*q*q+q*q*q*q*q*q);
	A=-27*(p*p*p*p+14*p*p*q*q+q*q*q*q);       

	       //output to file
      }
    }
  }
}
 
int Pionare::Gcd(int a,int b){
int rem;
 cout<<a<<endl<<b<<endl;
while (a !=0)

{
  rem = a % b;

a= b;

b = rem;
}

return (a);
}
