    Stack in C++ programming

    A Stack is a linear data structure which is used to store data in a particular order. Two operations that can be performed on a Stack are: Push operation which inserts an element into the stack. Pop operation which removes the last element that was added into the stack. It follows Last In First Out(LIFO) Order. Today I have just studied about Stack and thought I should share a program of Stack here with you all.

    #include < iostream.h >
    #include < stdlib.h >
    #include < stdio.h >

    class IntStack
    {
    public:
       IntStack(int num) {  top = 0; maxelem = num; s = new int[maxelem]; }
       void  push(int t)
       {
          if (top == maxelem) return;
          s[top++] = t;
       }
       int pop()
       {
          if (top == 0) return -1;
          return s[--top];
       }
       void display()
       {
         if (top == 0) { cout push(2);
       s->display();
       s->push(3);
       s->display();
       s->push(4);
       s->display();
       s->pop();
       s->display();
       s->pop();
       s->display();
       s->push(10);
       s->display();
       s->pop();
       s->display();
       s->pop();
       s->display();
       s->pop();
       s->display();
       s->pop();
       s->display();
       s->pop();
       s->display();
    }
