Problem declaring member functions with class template

[Coasterfan87]

Whats wrong with my member function Greet()? I am using a class template so i can have instances of my class Critter in a vector array. My problem is that i can't figure out how to declare member functions when using a class template. Any suggestions would be appreciated? Thanks!

#include <iostream>
#include <string>
#include <vector>

using namespace std;

template <typename T>
class Critter : public vector<T>
{
	public:
		int m_Hunger;
		void Greet(void);
};

void Critter::Greet()
{
    cout << "Hi. I'm a critter. My hunger level is " << m_Hunger << ".\n";
}

int main()
{
	Critter<int> crit_array;

	crit_array.push_back( crit_array.size() ); //1
	crit_array.push_back( crit_array.size() ); //2
	crit_array.push_back( crit_array.size() ); //3 
	crit_array.push_back( crit_array.size() ); //4 
	crit_array.push_back( crit_array.size() ); //5

	system("pause");

    return 0;
}

This code gives me the following error:

Error 1 error C2955: 'Critter' : use of class template requires template argument list

btw: the class is derived from Micheal Dawsons book Beginning C++ Through Game Programming

Your function should be:

template <typename T> void Critter<T>::Greet()
{
    cout << "Hi. I'm a critter. My hunger level is " << m_Hunger << ".\n";
}

Hope this helps. :-)
