How do I insert and erase elements efficiently with std::stack?

This guide explains how to efficiently insert and erase elements using the std::stack in C++. A stack is a container adaptor that provides a LIFO (last in, first out) data structure, making it easy to manage data in a specific order. Learn how to manipulate elements within a stack for better performance in your C++ applications.

        #include 
        #include 

        int main() {
            std::stack myStack;

            // Insert elements into the stack
            myStack.push(10);
            myStack.push(20);
            myStack.push(30);

            // Display top element
            std::cout << "Top element: " << myStack.top() << std::endl;

            // Erase the top element
            myStack.pop();
            std::cout << "Top element after pop: " << myStack.top() << std::endl;

            // Clear the stack
            while (!myStack.empty()) {
                std::cout << "Removing: " << myStack.top() << std::endl;
                myStack.pop();
            }

            return 0;
        }
