template should work

[lare26]

I created my very first template. I had the first 2 parts by themselves and they worked fine. I added a third and now the first doesn't work. What am I doing wrong?

#include <iostream>

using namespace std;

template <class T, class U, class V>
T mult(T a, U b){return (a*b);}//worked fine
template <class T, class U, class V>
T mult(T a, U b, V c){return ((a*b)*c);}//worked fine
template <class T, class U, class V, class W>
T mult(T a, U b, V c, W d){return (((a*b)*c)*d);}//compiler is'nt complaining about this

int main()
{
    double i;
    cout << mult(2,2)//compiler now says no matching function
    << "\t"
    << mult(0.5,2,0.5)//this still works fine
    << endl;

    return 0;
}

There is no matching function for mult(2,2) - You are probably thinking that this one

template <class T, class U, class V>
T mult(T a, U b){return (a*b);}

would match.
But you will notice that you have not accounted for the template parameter V.

Dude.... i feel like such a moron. At least I would if I hadn't been up for something like 20 hours strait. I'm at 25 hours now. LOL Thanks guestgulkan. :o)
