With the following two constructors, we can create Rectangle objects in different ways: Rectangle r1; // Uses default constructor with no parametersRectangle r2(4, 5); // Uses constructor with two integer parameters In addition to overloading constructors with different parameters, we can overlo...
2) Difference is Return type.3) Difference in Function, with Multiple Arguments.4) Difference in Data Type. 1) Constructor Overloading: Constructor overloading is that in which a Constructor has a same name and has multiple Functions, then it is called as Constructor Overloading. As we ...
Applications of the Friend Function Here are the top five applications of friend functions in C++: Operator Overloading: Friend functions are commonly used for overloading operators, such as `+`, `–`, `==`, etc., to provide custom behaviors for user-defined types, making complex operatio...

Prerequisite:operator overloading and its rules What are nameless temporary objects in C++? Sometimes to reduce the code size, we create nameless temporary object of class. When we want to return an object from member function of class without creating an object, for this...

overload here is some facility to create an overload set from multiple lambdas, and is commonly used for variant visitation. See cppreference, for example. This counts the number of leaves in the tree through recursion. For each function call in the call graph, if the current is a Leaf,...
This error is inside a function defined as int calculate_number_of_cats(const house& h). The GitHub Copilot message says: "The value of the expression it is NULL, which means that the iterator is not pointing to any valid element in the vector animals_. In the context of your program...
