First look at the code:1 #ifndef Strcat_h2 #defineStrcat_h3 4 /*******************************************************************5 prototype: extern char *strcat (char *dest,char *src);6 7 strcat () copies the parameter SRC string to the trailing

Friend: Assuming that B is my friend in a, then I can use all of my (A) data, including private type data, within B.The appearance of friends destroys the encapsulation and concealment of classes.Friend in C + + is divided into: friend function and

This is a previous time to do http://fun.coolshell.cn/in a question, very interesting, involved in fact is the basis of C, but the first time I saw this line of code really confused me:printf (&unix["\021%six\012\0"], (Unix) ["has"" Fun"0x60);At

C Language Section1. Analysis of pointersint (*p) [5] and int *p[5]The former is a pointer to an array that contains 5 elements. The latter is an array with a length of 5, and each element in the array points to an integer variable.int *f (int i,

FeedTwo years ago I wrote this article-the implementation of the Vector class. Now it seems that the code is a little ugly.So, write it again.Refer to the interface of the Vector3 class of Unity3d. Words don't say much, on the code.Compiler: GCC 4.6.

Article 13: Managing Resources with objectsMany resources are allocated dynamically within the heap and are then used within a single chunk or function. They should be released when the control flow leaves that block or function. The auto_ptr

Article 05: Understand what functions C + + silently writes and callsThe compiler defaults to declaring a default constructor, a copy constructor, a copy assignment operator, and a destructor. These functions are both public and inline. 1 class

Understanding1. The singleton mode is used to replace global static variables. C + + uses static member variables to achieve global uniqueness of class instances. 2. The instance () method is the only invocation entry provided by a single piece.Key

C/C ++ -- hexadecimal String Conversion In practice, conversion between strings and other data types is very common. There are many library functions, suchAtoi,Strtol,SscanfEtc. These functions have a lot of information on the Internet, What I often

What C ++ list size () comes to mind, listsize Valid STL focuses on listing in an Item. size () is an O (n) efficiency. At that time, I just wrote down the efficiency. Later I saw some people in csdn encountered a pitfall in the actual project. I
