On the logical shift, the arithmetic shift can be seen in the Thunder deep large part of the question. A problem.
Previously seen in C + + standard, the behavior of the shift operator (>) out of bounds is not certain:
The behavior is undefined if
1 What is a C-language implicit function declaration
In the C language, a function does not have to be declared before it is invoked. If there is no declaration, the compiler automatically generates assembly code for the C code of the calling
Modern compilers are generally compiled by file, so at compile time, the global variables defined in each file are opaque to each other. That is, at compile time, the visible domain of the global variable is limited to the inside of the file. (Some
In the use of VC programming, in order to speed up the compilation, the VC compiler provides precompiled functionality. That is to include stdafx.h in the CPP code, you can use it to precompile.
the following are as follows:
Copy Code code as

To write data structures that can be ported between different platforms, you should always force the natural alignment of the data items in addition to the specific
This paper mainly introduces the two methods of using different or solving problems in C + + programming.

Suppose you schedule a weekly fitness schedule, and each day's optional items include:
Note: This installation method also applies to QT version 4.6.
For space reasons, all the pictures in the text are omitted.
Here we take Ms Visual Studio version 2008 as an example to illustrate the integrated use of QT 4.5, which is also useful
A child Boots the day before yesterday to the ideal international company interview, came back in the dormitory discussed such a question:
VC + +, there is an empty class, did not declare any member variables or functions, I would like to ask this
1. The role of __attribute__ ((packed)) is to tell the compiler to cancel the optimization alignment of the structure during compilation, aligned according to the actual number of bytes consumed, and is a unique syntax for GCC. This feature is not
First, the preface
RTTI (run-time type information) is one of the features commonly supported by modern advanced programming languages, such as "A is a" in C #, and "a instanceof a" in Java belongs to the category of RTTI. However, Symbian OS C + +
I don't remember where I got a MD5 encryption class, because of the reason for development to use MD5 encryption in WTL, but this class is not directly used in the WTL (in the MFC it was a easy job), so I modified, and write this article, To
use uses_conversion with caution
Uses_conversion is a macro definition in ATL. Used for encoding conversions (more is CString to LPCWSTR conversion). Use to include header files under ATL # # "Atlconv.h"

Mainly talk about VC inside the function call assembly into the assembly code of the case, first for a small program before, say VC compiler optimization.
Example program:

using namespace Std;
int main (int argc, char* argv[])

Lambda Expressions in C ++Lambda expressions in C ++
In Visual C ++, a lambda expression-referred to as a lambda-is like an anonymous function that maintains state and can access the variables that are available to the enclosing scope. this article
