Program:

#include<iostream>
#include<conio.h>
using namespace std;
class Stack
{
    int stk[10];
    int top;
    public:
    Stack()
    {
    top=-1; 
    }

//This funtion is used to push an elemnt into stack
    void push(int x)
    {
        if(isFull())
        {
            cout <<"Stack is full";
            return;
        }
        top++;
        stk[top]=x;
        cout <<"Inserted Element:"<<" "<<x;
    }

    //This functionn is used to check if the stack is full
    bool isFull()
    {
        int size=sizeof(stk)/sizeof(*stk);
        if(top == size-1)
        {
            return true;
        }
        else
        {
            return false;
        }
    }

    //This function is used to check if the stack is empty
    bool isEmpty()
    {
        if(top==-1)
        {
            return true;
        }
        else
        {
            return false;
        }
    }

    //This function is used to pop an element of stack
    void pop()
    {
        if(isEmpty())
        {
            cout <<"Stack is Empty";
            return;
        }
        cout <<"Deleted element is:" <<" "<<stk[top--];
    }

    //This function is used to display the elements of the stack
    void display()
    {
        if(top==-1)
        {
            cout <<" Stack is Empty!!";
            return;
        }
        for(int i=top;i>=0;i--)
        {
        cout <<stk[i] <<" ";
        }
    }
};

void main()
{
    int ch;
     Stack st;
     while(1)
        {
             cout <<"\n1.Push  2.Pop  3.Display  4.Exit\nEnter ur choice";
             cin >> ch;
             switch(ch)
              {
               case 1:  cout <<"Enter the element you want to push";
                        cin >> ch;
                        st.push(ch);
                        break;
               case 2:  st.pop();  
                        break;
               case 3:  st.display();
                        break;
               case 4:  exit(0);
               }
         }
}

Sample Output:

1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 1
Enter the element you want to push 11
Inserted Element: 11
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 1
Enter the element you want to push 22
Inserted Element: 22
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 1
Enter the element you want to push 33
Inserted Element: 33
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 1
Enter the element you want to push 44
Inserted Element: 44
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 1
Enter the element you want to push 55
Inserted Element: 55
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 3
55 44 33 22 11
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 2
Deleted element is: 55
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice 3
44 33 22 11
1.Push  2.Pop  3.Display  4.Exit
Enter ur choice
