Thread: Templates

I have a template queue class and I need to define it in another class which isn't templated how do I go about doing that? Do I need to make all classes using the Queue template classes?

a little example:

Code:

template <class T>
class Queue{
    .
    .
    .
};


class School{

public:
   . 
   .
private
   Queue<T> firstGraders;
};

this is what I would like to do and School would be declared in main

If you want School to be a template you have to declare it as such and the data type passed to School will be passed to Queue:

Code:

template<class T>
class School{

public:
   . 
   .
private
   Queue<T> firstGraders;
};

If you do not want School to be a template you have to instantiate Queue with an actual type in School:

Code:

class School{

public:
   . 
   .
private
   Queue<Student> firstGraders; // Student class defined somewhere else 
};

Thanks
