this is my code:
#include <iostream>
#include <stdlib.h>
using namespace std;
int GCD (int, int);
int main ()
{
static int num;
static int den;
cin >> num >> den;
cout << num << " " << den << endl;
GCD (num, den);
cout << GCD(num,den) << endl;
num /= GCD (num,den);
den /= GCD (num,den);
cout << num << " " << den << endl;
system("PAUSE");
return 0;
}
int GCD (int numerator, int denominator)
{
int r, gCD;
while (r != 0 ){
if (r == 1){
cout << "Already Simpilfied." << endl;
break;
}
else if (numerator < denominator){
r = denominator % numerator;
denominator = numerator;
numerator = r;
}
else if (numerator > denominator){
r = numerator % denominator;
numerator = denominator;
denominator = r;
}
}
if (r == 1)
return gCD =1;
else if (numerator < denominator){
gCD = denominator;
return gCD;
}
else if (numerator > denominator){
gCD = numerator;
return gCD;
}
}
and this is the output:
36 21
36 21
3
12 1
Press any key to continue . . .
that number "1" is supposed to be denominator but it''s supposed to say "7" instead. but no matter what numbers i put i keep getting 0 or 1.
someone please help.
