QStackstack; stack.push(1); stack.push(2); stack.push(3); int top = stack.pop(); // top is now 3, stack is now {1, 2}
QStackIn this example, we create a QStack of QStrings and push the elements "apple" and "banana" onto the stack. We then use the pop() method to remove the top element ("banana") and assign it to the variable top. The QStack class is part of the Qt Core package.stack; stack.push("apple"); stack.push("banana"); QString top = stack.pop(); // top is now "banana", stack is now {"apple"}
