What are the differences between stack and queue in C++?

In C++, a stack is a LIFO (Last In, First Out) data structure, while a queue is a FIFO (First In, First Out) structure.

Can you give me examples of how to implement both in C++?

Sure! For a stack, you can use std::stack and for a queue, std::queue. Would you like to see code snippets?

Yes, please provide the code snippets for both.

Here's a simple stack example:

#include <stack>
std::stack<int> myStack;
myStack.push(1);
myStack.push(2);
int top = myStack.top(); // top is 2

And for a queue:

#include <queue>
std::queue<int> myQueue;
myQueue.push(1);
myQueue.push(2);
int front = myQueue.front(); // front is 1

What are the use cases for stack and queue?

Stacks are often used in function calls and backtracking algorithms, while queues are used in scheduling and buffering.
