Why does this works : template <typename T> struct foo { }; struct A { typedef foo<A> type; }; struct B : public A
I have a: class ServiceObject { ServiceClass svcClass; void execute(String operation, Map arguments, ...) {
The following snippet produces an \"ambigious call to foo\" error during compilation, and I\'d like to know if there is any way around this problem without fully qualifying the call to foo:
I\'m getting build errors when passing an object that implements multiple interface to a function that requires only 开发者_JAVA技巧one of the interfaces.
I don\'t know why I can\'t find an 开发者_运维百科answer to this online. I have classes that implement multiple methods and I would like to write methods to expect them. I don\'t know how to do it th
I\'m Programing in C++, and I have 3 classes that inherit from each other: Hatchback -> Car -> Vehicle;
I understand that C# does not support multiple inheritance, and that the solution is to use interfaces instead. But what I don\'t understand is why interfaces doesn\'t create the dia开发者_如何学运维m
I\'m trying to do something like C# explicit interface implementation in unmanaged C++.I am able to do it so long as the function implementation is part of the class definition but I can\'t figure out
Say you have an Interface A, and an Interface B. Let\'s say the Sprite class implements both interfaces.
I ran into a confusing situation today that I\'m hoping someone can explain to me. I have a C++ program with 4 classes:
