What are some examples of using the C++11 standard stack?

Can you give me some examples of how to use the C++11 standard stack?

Sure! The C++11 standard stack is part of the STL and can be used to manage a collection of elements. Here's a simple example:

#include <iostream>
#include <stack>

int main() {
    std::stack<int> myStack;
    myStack.push(1);
    myStack.push(2);
    myStack.push(3);

    while (!myStack.empty()) {
        std::cout << myStack.top() << std::endl;
        myStack.pop();
    }
    return 0;
}

What does the top() function do in this context?

The top() function returns a reference to the top element of the stack without removing it. In the example, it allows you to access the last pushed element.

Can you explain how push() and pop() work?

Certainly! The push() function adds an element to the top of the stack, while pop() removes the top element. This follows the Last In, First Out (LIFO) principle.

Are there any other useful functions in the C++11 stack?

Yes! Besides push(), pop(), and top(), you can use empty() to check if the stack is empty and size() to get the number of elements in the stack.
