Object not actually being modified by a class method

krityx (6)
I have this constructor for my rational class:
1
2
3
4
5
6
 
rational(int a,int b)
	{
		num=a;
		denom=b;
		simplify();
	}


simplify() is a private method within the same class.

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
void simplify()
	{
		
		if(denom<0)
		{
			num = num * (-1);
			denom = denom * (-1);
		}
		int x=gcd(num,denom);
		if(x!=1)
		{
			num /= x;
			denom /= x;
		}
	}


In main :
1
2
3
4
5
6
7
8
 
int main()
{
	rational a(3,-2);
	cout<<a.get_num()<<" "<<a.get_denom();
	system("pause");

	return 0;
}

ok so it should actually set a to be -3,2 but it displays 3,-2. Everything seems to be correct and it's driving me crazy..

Does your gcd function handle negative values? gcd should never return a negative value.

Oh yeah that was it.. gcd was -1 and it was dividing by -1 ... Thanks.
