Menu Driven C++ Program for Stack

Overview

Stack is data structure with LIFO order (Last In First Out). In this tutorial, we will develop a C++ program menu based program for the Stack operations.

C++ Program

#include<iostream>
#define MAX 10
using namespace std;

int arr[MAX];
int item;
int ch;
int top=-1;
int stackCount=0;

//push operation
void push(int stack[],int item)
{
    if(top==(MAX-1))
        cout << "Stack Overflow..." << endl;
    else
    {
        top=top+1;
        stack[top]=item;
        stackCount++;
    }
}

//pop operation
int pop(int stack[])
{
    int itemTop;
    if(top==-1)
        cout << "Stack Underflow..." << endl ;
    else
    {
        itemTop=stack[top];
        top=top-1;
        stackCount--;
        cout << "Pop item is " << itemTop << endl ;
    }
    return itemTop;
}


//display
void display(int stack[])
{
    if(top==-1)
        cout << "Stack Empty" << endl;
    else
    {
     cout << "******************" << endl;
     for(int i=top; i>=0; i--)
    {
        cout << stack[i] << endl;
    }
    cout <<  "*******************" << endl;

        cout <<"4. Exit\n";
        cout <<"Enter your Choice:";
        cin >> ch;
        switch(ch)
        {
        case 1:
            cout << "Enter an element:";
            cin >> item;
            push(arr,item);
            break;
        case 2:
            item=pop(arr);
            cout << "Element poped " << item << endl;
            break;
        case 3:
            display(arr);
            break;
        case 4:
            exit(0);
        default:

            break;
