Ladies and gentlemen, crossing, the last time we talked about the example of a socket communication model, let's go on to that example. Gossip Hugh, words return to the positive. Let's talk C chestnuts together!Crossing, we introduced the two

C Language FunctionsFirst, the functionC language programs are composed of functions, each function is responsible for the completion of a part of the function, the function will be the work of the package, for the program to call.Second, function

The most common place to use C for bit operations is to write values on registers.I. Some basic concepts1. Bit and:&Operation: 1 & 1 = 1; 1 & 0 = 0; 0 & 0 = 0;Features: Only 1 is 1, and all other cases are 0.Summary: Any number and 0 bits with is 0,

First, the concept of arraysConstruction data type used to store a set of dataFeatures: Only one type of data can be stored, such as all int or all char, the data in the array becomes an element.Second, the definition of the arrayFormat: type array

first, the basic statementThe basic language of C is almost the same as in Java, so here's just a simple way to mention Loop statements (Do while, while, for) Conditional statements (if, if-else, switch) Goto statement  II.

Both virtual and abstract are used to decorate the parent class by overriding the definition of the parent class to redefine the subclass.They have one thing in common: if you are using a method, you must add public to the front, or you will get a

The LIMBDA expression is referenced in c#3.0, and the LIMBDA expression is actually a method, except that the method is an anonymous method (that is, a method without a name)Code snippet: func t= (int x, string b) = = (X.tostring () + B), as follows:

Mutable and volatile keywords: mutablevolatile 1. mutable In C ++, mutable is set to break through the const restrictions. Variables modified by mutable will always be in a mutable state. Even if the struct variable or class object in a const

Dynamic_cast, RTTI, sorting, dynamic_castrtti The main reference is to understand the memory layout, and then write an instance program to understand it, but you need to be familiar with pointer conversion. 1) only polymorphism classes have RTTI
