Implements stack class as a template

Demo Code

#include <iostream>
using namespace std;
const int MAX = 100;
template <class Type>
class Stack// w  w w  .j  a va2s .co m
{
   private:
   Type st[MAX];             //stack: array of any type
   int top;                  //number of top of stack
   public:
   Stack()                   //constructor
   {
      top = -1;
   }
   void push(Type var)       //put number on stack
   { st[++top] = var; }
   Type pop()                //take number off stack
   { return st[top--]; }
};
int main()
{
   Stack<float> s1;      //s1 is object of class Stack<float>
   s1.push(1111.1F);     //push 3 floats, pop 3 floats
   s1.push(2222.2F);
   s1.push(3333.3F);
   cout << "1: " << s1.pop() << endl;
   cout << "2: " << s1.pop() << endl;
   cout << "3: " << s1.pop() << endl;
   Stack<long> s2;       //s2 is object of class Stack<long>
   s2.push(123123123L);  //push 3 longs, pop 3 longs
   s2.push(234234234L);
   s2.push(345345345L);
   cout << "1: " << s2.pop() << endl;
   cout << "2: " << s2.pop() << endl;
   cout << "3: " << s2.pop() << endl;
   return 0;
