Variables declared inside the class definition, but not inside a method are class or static variables: As @millerdev points out, this creates a class-level i variable, but this is distinct from any instance-level i variable, so you could have This is different from C++ and Java, but not so different from C#, where a static member can’t be accessed using … Read more
You’re defining the class in the header file, include the header file into a *.cpp file and define the class a second time because the first definition is dragged into the translation unit by the header file. But only one gameObject class definition is allowed per translation unit. You actually don’t need to define the … Read more
Is it possible to assign multiple classes to a single HTML container? Something like:
What is the difference between these two code samples? 1: 2:
You are trying to call DeckOfCards::shuffle with a deckOfCards parameter: But the method takes a vector<Card>&: The compiler error messages are quite clear on this. I’ll paraphrase the compiler as it talks to you. Error: Paraphrased: Hey, pal. You’re trying to call a function called shuffle which apparently takes a single parameter of type reference-to-deckOfCards, but there is no such function. Error: … Read more
The Pythonic way to create a static class is simply to declare those methods outside of a class (Java uses classes both for objects and for grouping related functions, but Python modules are sufficient for grouping related functions that do not require any object instance). However, if you insist on making a method at the … Read more
Is it possible to assign multiple classes to a single HTML container? Something like:
C++ has two kinds of enum: enum classes Plain enums Here are a couple of examples on how to declare them: What is the difference between the two? enum classes – enumerator names are local to the enum and their values do not implicitly convert to other types (like another enum or int) Plain enums … Read more
If you will place your definitions in this order then the code will be compiled The definition of function doSomething requires the complete definition of class Ball because it access its data member. In your code example module Player.cpp has no access to the definition of class Ball so the compiler issues an error.
Private members are only accessible within the class defining them. Protected members are accessible in the class that defines them and in classes that inherit from that class. Edit: Both are also accessible by friends of their class, and in the case of protected members, by friends of their derived classes. Edit 2: Use whatever … Read more
