cout << "GCD of two number is: " << x << endl;
else
/* Call the common_divisor function inside in it */
common_divisor(y, x % y);
}
int main() {
int a, b;
cout << "Enter two positive number to find Greatest Common Divisor:" << endl;
/* read two integer from console and store it in "a" and "b" */
cin >> a >> b;

return 0;
}

Enter two positive number to find Greatest Common Divisor:

30

20

GCD of two number is: 10
