If you have two classes, class a and class b, could you create a variable in class a from class b? main.cpp class A { public: A() {} }; class B { public: B() { test = A(); test.<variable name> = <variable value>; } }; The code above is just an example. It will probably… Read More Creating a public variable from another class (C++)

What I need is a function that removes and returns previously… Read More Pop an object from a class list
How can I make two instances of a class, update the same array from that class? Like here, I want r1 and r2 to update same pendingOrders, so that finally the array is [‘yo’, ‘lo’]. That is not happening, the r1 and r2 are making different arrays. import java.util.ArrayList; public class Student{ static int enrollmentNumber;… Read More How to update a single array using multiple instances of a class

As we all know, if you have a function like this: def foo(): foo() The function will call itself 1000 times and then you get a RecursionError exception. But what if you had a thousand and one different functions that call each other? i.e. a() calls b() calls c() and so on. Would you get… Read More Are there separate call tree depths for recursive and non-recursive calls?
Any instance of the class Square starts as an integer equal to 2. When the square_me method is called on the instance, the instance is multiplied by itself. This can be done any number of times (e.g. calling square_me once on an instance results in the value 4, and calling square_me again on the same… Read More How to add up all instances of a class. This total value will be available through the class as well as any of the instances
