Define Functions out of Class template in C++ -

i've been faced error class stack' used without template parameters" > while trying make template stack class

template <class t> class stack{                        /// declare new class named stack  private :     t* data;     int pointer;     int size1;  public :     t pop();     t top();     bool push(t);     bool isfull();     bool isempty();     stack(int size1)     {         this->size1 = size1;         pointer = 0;         data = new int [size1];     }     ~stack()     {         delete [] data;     }  }; 

the real problem want define functions outside of template class!!(for more readability) doesnt work!!

here's defenition 1 of functions :

template <class t> bool stack<t>::isfull() { if(pointer==size1+1)     return true;  return false; } 

if function's definition steps class code block , works fine ...?!

this how call in main : stack operator(size) ;

have missed out <t> 1 of function definitions? i.e. have this:

template <class t> bool stack::isempty() 

instead of this:

template <class t> bool stack<t>::isempty()           ^^^
