GREATER COMMON DIVISOR

C++ Program Finding Greater Common Divisor

#include<iostream>

using namespace std;

unsigned int gcd (unsigned int n1, unsigned int n2)
{

    unsigned int tmp;

    while (n2 != 0) {

        tmp = n1;

        n1 = n2;

        n2 = tmp % n2;

    }

    return n1;

}

int main()

{

unsigned int gcd(unsigned int,unsigned int );

int num1,num2;

cin>>num1;

cin>>num2;

cout<<"greater common divisor is :"<<gcd(num1,num2)<<"\n";

system("pause");

}
