Is there a need performance-wise for inline functions to pass its arguments by const reference like foo(开发者_开发百科const T & a, const T &b)
This may be impossible, but I was wondering if it was possible to keep a temporary from ever lasting past its original expression. I have a chain of objects which point to parent objects, and a member
I was just building one of our projects at work and I see a new function was added: const std::string& ClassName::MethodName() const
Generally this discussion is up to the local function variable only: void foo (const int &i) { // use i till foo() ends
Section 12.2.5 in C++03 says \"A temporary boun开发者_如何学Pythond to a reference member in a constructor’s ctor-initializer (12.6.2) persists until the constructor exits\"
Consider this code, struct A {}; struct B {B(const A&) {} }; void f(B) { cout << \"f()\"<<endl;
I have this sample code: struct A { bool test() const { return false; } }; template <typename T = A> class Test
I really admire java features and I don\'t want to give up us开发者_开发问答ing it for the next problem:
I have some code that uses an iterator to loop through all elements of an unordered_map, but within that loop there are several other processes where I store iterators to particular elements in the ma
Suppose we have an abstract class Element from which classes Triangle and Quadrilateral are derived from.
