What is the C++11 standard queue?

Can you explain what the C++11 standard queue is?

The C++11 standard queue is a container adapter that provides a FIFO (first-in, first-out) data structure. It allows you to add elements to the back and remove elements from the front.

What are the main functions of the queue?

The main functions include push() to add elements, pop() to remove elements, front() to access the first element, and empty() to check if the queue is empty.

How do I include the queue in my C++ program?

You can include the queue by adding #include <queue> at the top of your C++ file. This gives you access to the queue functionalities.

Can you give me a simple example of using a queue?

Sure! Here's a simple example:

#include <iostream>
#include <queue>

int main() {
    std::queue<int> q;
    q.push(1);
    q.push(2);
    std::cout << q.front(); // Outputs 1
    q.pop();
    std::cout << q.front(); // Outputs 2
    return 0;
}
