Structures C struct vs C++ class C struct functions are loosely correlated with paramaters, parameters are usually passed via pointer, it may look like array for struct with 2 identical parameters in struct, for structures created dynamically look for malloc with non-usual size. C++ class Find constructor, it have always 1 argument (this pointer -> thiscall), main() function have initialization function __main with ctor initlizers, after creation of class with new operator the class constructor is called (can be empty), Methods are called with thiscall convention. Inheritance Constructors of base class are called 1st in child class, additionally assigment to variables in class definition is put inside constructor: ...
