On Line 25, it states that Bigger is not a type - why is that?

#include <iostream>
using namespace std;

template <class AnyDataType>
class Bigger
{
 public:
        Bigger(AnyDataType firstNumber, AnyDataType secondNumber)
        {
                    number1=firstNumber;
                    number2=secondNumber;
        }
        AnyDataType bigger()
        {
         return (number1>number2)?number1:number2;
        }
        
 private:
         AnyDataType number1;
         AnyDataType number2;
};

int main()
{
     Bigger<int> *b = new Bigger(5,10);//error.
     cout<<b->bigger()<<endl;
     return 0;
}

It's because you've used "class" as a type not "typename". "class" cannot hold numerical types.

Replace line 4 with this line:

template <typename AnyDataType>

You should only use "class" instead of "typename" if you are passing classes.

that didn't work :(

You really should get a default constructor...

Anyways. Look carefully at how you use your constructor. Are you missing something? Maybe another set of these? <>

Albatross is right. You need another <int> in line 25.

// In line 25.
Bigger< int > *b = new Bigger< int >( 5, 10 );

Thanks! That solved it.
