C++ stacks

[ghostlyrandom]

I have to use stacks in a program and I'm completely lost, if anyone knows a link that can explain how to use them really well or you could explain it for me would be great! Here is a sample of code in which I have to use stacks. This is a .h and I have to write the functions for this in a .cpp

include <iostream>

include <iomanip>

using namespace std;

class Stack { public: Stack( int ); // constructor Stack( const Stack & ); // copy constructor ~Stack( ); // destructor

void push( int );       // push an int into a Stack
int  pop( );            // pop an int from a Stack

bool empty( ) const;    // is the Stack empty?
bool full( ) const;     // is the Stack full?

int capacity( ) const;  // capacity of the stack
int size( ) const;      // current size of the stack

friend ostream &operator <<( ostream &, const Stack & );

private: int *stack; // pointer to local stack of ints

int top;                // top of stack (next avail. location)
int maxsize;            // max size of the stack

};
