Thread: Using comparing operetors on variables defined by Templates

I cant figure out the syntax for how to create new operators such as '<', '>', '==', etc. for variables defined by Templates

for example:

/////////////////////////////////////////////////////////////////////////////
template <class T>
class Whatever
{
private:
T tData;
public:
tData GetLargest(tData, tData);
};

tData Whatever<T>::GetLargest(tData tD1, tData tD2)
{
if(tD1 > tD2) return tD1;
else return tD2;
}

void main(vodi)
{
Whatever <unsigned int> W;
W.GetLargers(2, 4);
}

/////////////////////////////////////////////////////////////////////////////

Now this will work since '<' is not defined for this type, so my question is, how do i make my own operator when it has to do
with templates?

thx

As long as < is defined for the data type when the template is instantiated then you can call GetLargest(). Your class isn't working because your confusing instances of variables with their types -

Code:

#include <iostream>

using namespace std;

template <class T> 
class Whatever 
{ 
	private: 
	T tData; 
public: 
	T GetLargest(T t1, T t2); 
}; 

template<class T>
T Whatever<T>::GetLargest(T tD1, T tD2) 
{ 
	if(tD1 > tD2) return tD1; 
	else return tD2; 
} 

int main() 
{ 
	Whatever <unsigned int> W; 
	cout << W.GetLargest(2,4); 
	return 0;
}
