Visual Studio 2010 C ++ Compiler (VC10) supports six new C ++ 0x features: auto, right-value reference, static_assert, nullptr, lambda expressions, and decltype. Compared with the vc6, which was born before the standard was introduced, VC10 has

To avoid unnecessary copying of temporary objects, the C ++ compiler usually uses an optimization technique called copy ellision (copy removal), which includes at least two items: The return value optimization (RVO) prevents copy operations by

The following wonderful replies are from the C ++ discussion group: Why besides the type system? I haven't read every part of the discussion, but let me try to highlight some points of semantics here. I have not read all the sections in this

1. Why should I add the extern "C" to call the function compiled by the C compiler in the C ++ program "?A: First, extern is a keyword in the C/C ++ language that indicates the range of the function and global variable. This keyword tells the

This is the first time I used the multi-INHERITANCE OF C ++ and suffered a major setback. I was born stupid and did not have a strong understanding, so I never dared to touch this thing before. This time, I was forced to drive evil ideas. Not much

In most cases, pure C ++ code is not suitable for directly joining C ++/CLI projects. the same pure C ++ code is much less efficient in C ++/CLI projects than in native code. All inline, SSE commands, and automatic SIMD commands are invalid. If you

Recently, we have seen coroutine in unity3d, which is worth learning from.   Asynchronous operations are unavoidable in Server programming (especially Server Based on the event-driven framework. Traditional asynchronous operations may result in

Gamasutra has a very detailed article about the feature sored feature: behind the mirror-adding reflection to C ++. Rtti After the class declaration, the practice of adding rtti macros almost quickly becomes a standard for various engines.
