c++ - Is it possible to use inside a template class, a vector of class stack elements? -

i have "stack.h" , "stack.cpp" file define hand-made stack class.

what want now, create class "name" has in it's composition vector of "nr" stacks , i'm not sure start.

depou.h:

#pragma once #include <vector> #include "stiva.h"  template <class t> class depou { private:     int nr;     std::vector<stiva<t> > depouarray;  public:     depou (int x, int lungtren); };  template <class t> depou<t>::depou (int x, int lungtren){     int i;     nr = x;     depouarray = new std::vector<stiva<t> > (nr); /*  (i=0; i<nr; i++){         depouarray[i] = stiva<t> (lungtren);     } incorrect */ } 

my name.h doesn't compile want know if it's possible vector of kind.

my stack header called "stiva", edited "name.h" file according so.

stiva.h

#pragma once  template <class t> class stiva { private:     int top;     int size;     t *stackarray;  public:     stiva();     stiva (int s);     ~stiva (){ delete [] stackarray; }     int push (const t&);     int pop (t&);   int topelem (t&);     int isempty (){return top == -1;}     int isfull () {return top == size -1;}     int search (t x);     void setsize (const int& sz){         size=sz;     } };  template <class t> stiva<t>::stiva (){     size = 10;     top = -1;     stackarray = new t[size]; }  template <class t> stiva<t>::stiva (int s){     size = s>0 && s<1000? s : 10;     top = -1;     stackarray = new t[size]; }  template <class t> int stiva<t>::push (const t& x){     if (!isfull()){         stackarray[++top] = x;         return 1;     }     else{         size *= 2;         stackarray = (t*) realloc (stackarray, 2*size * sizeof(t));         stackarray[++top] = x;         return 1;     }     return 0; }  template <class t> int stiva<t>::pop (t& popvalue){     if (!isempty ()){         popvalue = stackarray[top--];         return 1;     }     return 0; }  template <class t> int stiva<t>::topelem (t& topvalue){     if (!isempty ()){         topvalue = stackarray[top];         return 1;     }     return 0; } 

in main initialize this:

depou d(5,10);

you can initialize vector given size in member intializer of constructor:

template <class t> class name { private:     int nr;     std::vector<stack<t> > namearray;  public:     name (int x) : nr(x), namearray(nr) {}     //other methods };
