Description: -Compiled in VS C++ Express Edition

-Using the C++ Standard Library
Implements a simple stack of integers. Can be modified to push user defined integers.

#include<iostream>

using namespace std;

#define MAX 10

class Stack
{
	int val[MAX];
	int top;
public:

	Stack();
	~Stack();

	void push(int a);
	void pop();

};

Stack::Stack()
{
	top = -1;
}

Stack::~Stack()
{
	cout<<"Desctructing"<<endl;
}

void Stack::push(int a)
{
	if(top!=MAX)
	{
		top++;
		val[top] = a;
		cout<<val[top]<<" is pushed"<<endl;
		cout<<endl;
	}
	else
	{
		cout<<"Stack is full"<<endl;
	}

}

void Stack::pop()
{
	if(top==-1)
	{
		cout<<"Stack is empty!"<<endl;
	}
	else
	{
		cout<<val[top]<<" is popped"<<endl;
		cout<<endl;
		val[top] = NULL;
		top--;
	}

}

	obj.push(10);
	obj.push(20);
	obj.push(30);

	obj.pop();
	obj.pop();
	obj.pop();

	cout<<endl;
	cin.get();

	return 0;
