What are the best practices for using std::stack in C++11?

When using std::stack in C++11, it's important to remember to use it for its intended purpose: LIFO (Last In, First Out) operations. Always ensure that you check if the stack is empty before popping an element to avoid exceptions.

Can you give me an example of how to implement std::stack?

Sure! 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 are some common mistakes to avoid when using std::stack?

Common mistakes include not checking if the stack is empty before popping, using it for non-LIFO operations, and not considering the underlying container's performance.

How does std::stack compare to other container types?

std::stack is specifically designed for LIFO operations, while other containers like std::queue are designed for FIFO. Each has its own use cases depending on the required data access pattern.
