1. colon (:) usage (1) represents the definition of the location domain in the structure (that is, the variable occupies several bit spaces) Typedef struct _ XXX { Unsigned char a: 4; Unsigned char c; } XXX; (2) The colon following the constructor acts as a segmentation function. It is a class-based method for assigning values to member variables. The initialization list is more suitable for the constant const type of member variables. Struct _ XXX {

DelegatePreface: C#1 already has the concept of entrust, but its complicated usage does not arouse much attention of the developer, in the c#2, some compiler optimizations are made, and an anonymous method can be used to create a delegate. At the same time, the conversion of method groups and delegates is also supported. By the way, the covariance and contravariance of delegates are increased in the

From: http://blog.csdn.net/Eric_Jo/archive/2009/05/14/4184916.aspx To understand what C ++/CLI is, first know what CLI is. 1. Introduction to CLI CLI :( common language infrastructure, universal language framework) provides a set of executableCodeAnd the specifications of the virtual execution environment required for running. More commonly, we can say that it is a virtual platform, operating system and application.ProgramA layer of abstraction

Learning Summary1, the circulation of the grammar and other languages are not bad, probably most of the language on the basis of the development of C, so much the same is not strange.2, in the judgment expression, only 0 of C language is considered false, all non-0 value positive integers are considered true.1#include 2 intMain () {3 if(0)4printf"0 is true\n");5 if(1)6printf"1 is true\n");7

[Mac 10.7.1 Lion x64 Intel-based gcc4.2.1 xcode4.2] Q: Explain the title.A: I vaguely remember that when I wrote A function with the absolute value of A value, it was really painful to write it to the third one. After repeating so many times, I immediately realized the significance of heavy load and STL.[Cpp]1. int abs (int n)2 .{3. return n 4 .}5.6. long abs_long (long n)7 .{8. return n 9 .}10.11. double abs_double (double n)12 .{13. return n 14 .}When I wrote the third function, I felt really

Why do I use exceptions in C + +?Many people may know about the anomaly mechanism in C + +, which many people may not know. Many people know what is commonly used in C assert , and know that it is specified at compile time NODEBUG to ignore it.For the C language, using normal if-else is a good choice, whereas in

3.4 Boolean TypeIn our daily life, we need to use a variable of type int to represent bus 216; A variable of type float is required to represent 3.5 yuan a pound of tomato, and sometimes it needs to represent a data, which is the logical state:"Have you passed the C + + exam this time?" ”"Does he really love me?" ”The "over-and-over" and "love-not-love" are all representations of a logical judgment. Compared with the bus line and the price of tomato w

C + + This is not what I wrote, I just see feel good, just paste the oh. ： Do not think that this topic is sensational, but in the current situation, C + + is required to exit the stage or to say that it is necessary to upgrade. I think that in the next year or two, as one of the criteria for programmer rating, C + + (whether MFC or BCB) will give way to three p

Because the company has always been engaged in C ++ development, because the customer needs to provide the C # version interface, I studied C # and found that it is powerful and concise, it is completely encapsulated in cross-language calls and provides powerful API interaction. this is much more convenient than JNA. both Java and

C ++FunctionAdvanced features Compared with C functions, C ++ adds four new mechanisms: overloaded, inline, const, and virtual. The overload and inline mechanisms can be used for both global functions and class member functions. The const and virtual mechanisms are only used for class member functions. Heavy Load and inline will certainly have their advantages to
