The most interesting C++ question I\'ve encountered recently goes as follows: We determined (through profiling) that our algorithm spends a lot of time in debug mode in MS Visual Studio 2005 with fun
I want to design a common interface which has a method that let me multiply two object which has this interface, returning a new object of the same class as the result. In order to keep it easy, I\'m
Before someone jumps and says Profile before optimize!, this is simply a curiosity question and stems from this original question.
Lets say we have the following code: std::vector<int> f() { std::vector<int> y; ... return y; }
Imagine: S f(S a) { return a; } Why is it not allowed to alias a and the return value slot? S s = f(t); S s = t; // can\'t generally transform it to this :(
I am wondering if in C++0x \"12.8 C开发者_如何学Copying and Moving class objects [class.copy] paragraph 31\" when copy elision happens, exactly:
I\'m fighting the following proposal now, and I want to know legal and for lesser extent moral arguments against it or for it.
Are there any compilers capable of performing return value optimization on multiple values returned from a function through std::tupl开发者_开发问答e? To be clear, in the following code, are there any
I think I\'ll get right into it and start with the code: #include <iostream> #include <fstream>
sorry for such a long question but I try to be as clear as possi开发者_如何学Goble. This somehow follows my previous question about strings in C++. I\'m trying to figure out how I could return std::st
