Pointers often haunt us in C programming, but the flexibility to use pointers will make programming easier and more efficient. Here's the difference between *p[n], (*p) [N], and **p, and this is where I've often been troubled.The definitions of these three are:int *p[n] represents an array of pointers, which means that

Tag: * P ++ * (p ++) (* P) ++ charch[3]={‘a‘,‘c‘,‘e‘};char*p=ch; 1, printf("%c\n",*p++);printf("%c\n",*p); Execution result 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/4D/A1/wKioL1RVt9yiIAlTAAAcwxIG2xM519.jpg "T

Reprinted please indicate the source: http://blog.csdn.net/wingfiring Some C/C ++ programming books once mentioned how to judge whether the pointer is null. obviously, if (P = NULL), if (P = 0), and if (p) can both complete this task. The difference lies in readability. we will discuss them separately. 1. If (P = NULL

When learning C language, pointer learning is a relatively difficult part, and it is often unable to distinguish * P P. The following is a test procedure for extracting others.Below is my short test programVoid test (){Int A = 8;Int * P = ;P = (int *) malloc (N * sizeof (INT ));// Printf ("% d/N", *

Why I run in the company is no problem, copy to my Computer, because my p used as a page value, so I each function in $p first error. Reply to discussion (solution) Please ask the landlord p = $p = = "? "1": $p; Do you think this is a ternary operation? $

Understanding the self-increment decrement operator(1) post-increment-decrement operator precedence > pre-increment decrement operator. (2) The pre-increment-decrement operator "variable is first self-decrement and then used". (3) The post-increment-decrement operator "variable is first used for re-increment self-decrement". 2. The * operator and the pre-increment-decrement operator are all 3-level operators, but the pr

We installed in the mobile phone "every day p map" you will see on the home page has a "Crazy change makeup" start cos Wu Mei Niang, as shown in the following figure. Then we open into the "crazy change makeup" Inside there are a lot of installed, such as queen makeup, Yangfei makeup, Weffei makeup, vampire makeup, such as a variety of 20 exquisite makeup can be selected. After choosing a good module, we can choose our own photos, th

First of all, do not think this writing is not good, but also stressed that the great God generally do not write this code, readability is not highIn fact, your C language Foundation is too poor, read do not understand, the great God really is so written. You can look at some of the words in C library functions*p++: * and + + are sibling operators, right-associative. But + + to calculate the entire expression operation, first extract

In fact, this daily p figure inside the sage is a ready-made module, we just have to put their own photos and then select the module can be, specific as follows. The sage makeup Play: The first step: the mobile phone installed the latest version of every day p map, and then click Daily P Figure app open into the homepage, click Crazy Change Makeup. Step
