Here is my code how do I display what is in the stack?


#include <iostream>
#include <stack>
 
using namespace std;
 
void Menu();
void Add();
void Display();
void Remove();
 
stack<int> stackInt;
int name;
 
int main()
{
	Menu();
}
void Menu()
{
	int choice;
 
	cout << "Stack Menu Options\n";
	cout << "1 - Add int to stack\n";
	cout << "2 - Remove from top of stack\n";
	cout << "3 - Size of stack\n";
	cout << "0 - Quit program\n";
	cout << "Enter choice: ";
	cin >> choice;
	cout << endl;
 
	switch(choice)
	{
	case 1:
		Add();
		break;
	case 2:
		Remove();
		break;
	case 3:
		Display();
		break;
	case 0:
		exit(0);
	default:
		cout << "Not a selection, enter again!\n";
		Menu();
		break;
	}
}
 
void Add()
{
	cout << "Enter a number to add: ";
	cin >> name;
	stackInt.push(name);
	cout << endl;
	Menu();
}
 
void Display()
{
 
}
 
void Remove()
{
	stackInt.pop();
	Menu();
}

there is a simple recursive way

void Display()
{
   if (! stackInt.empty()) {
      int top = stackInt.top();
      cout << top << endl;
      stackInt.pop();
      Display();
      stackInt.push(top);
   }
}

I wouldn't do it recursively if I were you. Depending on how big the stack is, you might run out of (program) stack space. Which is bad.

It's not very proper either, as the code actually empties the stack. What if the code is multi-threaded ? A display should not modify the contents of the container.

The STL stack does not provide a way to show its contents. So, I'd rather implement my own stack if I really need display functionality.
