Geju on Rare Linux is a published version, the typical Linux release version includes the Linux kernel, desktop and a variety of common essential tools, the international use of more is Ubuntu (Bantu), CentOS, Deepin (Deep Linux). This tutorial

First, Introduction Since we were just beginning to write a simple C + + "hello,world! "To compile it, run the results-this part of the work of the IDE (integrated development environment) has helped us, including syntax error checking, compiling,

First look at a code, it is estimated that many students have encountered one of them.#include #includeusing namespacestd;intMain () {intA =5; printf ("a++ =%d\n", a++); A=5; printf ("++a =%d\n", ++a); A=5; printf ("A + = a++ =%d\n", A + = a++); A=5;

float and doubleThe number of decimal points is a floating point. There are two ways to write floating-point numbers in C, one is to use commonly used standard decimal notation , as follows: 0.000568.01.23 The second means that

For automatic initialization of built-in variablesCode Listing 1:#include #defineCONST 100int*P1;inta[2];intb;Static intC;main () {intD; Static inte; intf[2]; int*P2; printf ("const=%d\n", CONST); printf ("a[0]=%d\n", a[0]); //printf ("*p1=%d\n", *P1

The whole code is divided into many small modules, initialization module, display module, adjustment module, running module. Also hope that Daniel can give further optimization of the recommendations and improvements. The code is as follows:#include

For the following programs:intBarintCintd) { intE = c +D; returne;}intFoointAintb) { returnBar (A, b);}intMainvoid) {foo (2,3); return 0;}With the-G option at compile time, the C Code and assembly code can be interspersed with objdump to

C + + exception handling, the previous student stage in the first time to learn C + +, feel really good unfamiliar, how to understand do not understand, later in the work, again encountered this problem, decided to write a blog record;Note is the

Fortunately today is the weekend, there is time to take note of this problem. Switching between multiple languages, found that the development efficiency drop is very low, the development costs are concentrated on the mode, C/s, the abandonment for

#region//Auto-run on bootprivate void Cb_auto_checkedchanged (object sender, EventArgs e){//cb_auto is a checkbox,isautorun is a Boolean variable that controls whether the boot runsif (cb_auto.checked = = true) Isautorun = true;else Isautorun =

How is the program's error log recorded?You can catch an exception when you encounter an exception, and then output the exception information to a TXT file. /// ///error Log/// Public classLoghelper {Private Static ObjectLockflag =New

In the development of applications using C #, there is often a need to start the application automatically after booting, this is a very common requirement, the most general practice (here Win7 operating system as an example), open: start = "All

Today we are going to talk about inheritance, to be honest today is also my first contact.What is the concept of inheritance? Is that a class can inherit properties and methods (members) of another classInheritance is a very important feature in

Erase and vectorerase used in vector As a result of a previous misunderstanding of vector found in the use of the latest project, we found that we do not know much about vect, so we want to write a bit about it.Attention in vector usage. In this
