C programming language was developed in 1972 by Dennis Ritchie and Brian Kernighan at the Bell Telephone Laboratories (AT&T Bell Laboratories) for use with the Unix operating system for programming computer operating systems. C is a procedural oriented programming language.
C语言是在1972年由贝尔实验室的Dennis Ritchie和Brian Kernighan为开发操作系统，为Unix提供编程语言而实现的。它是面向过程的编程语言。
C was designed as a minimalist language to be used in writing operating systems for minicomputers, which had very limited memories compared with the mainframe computers of the period
C最初主要是用来为微机编写操作系统，因而被设计的“小巧”而又富于抽象力，因为和当时的大型机相比，微机的内存非常有限。
Also C was designed for implementing system software. Although C was designed for implementing system software,it is also widely used for developing portable application software.
当然，C也被设计成适于编写系统软件。虽然C是系统级编程语言，但在可移植应用软件开发领域，到处都可以看到它的身影。
The initial development of C was devised during 1969–73, alongside the early development of the UNIX operating system. It was based on CPL (Combined Programming Language), which had been first condensed into the B programming language and later on it was called as computer programming language by Ken Thompson, an American computer scientist and a colleague of Ritchie. Ritchie rewrote and restored features from BCPL to create C-Programming Language, rewrite the development of the Unix operating system in C language.
C的最初开发与实现是和UNIX系统一起进行的，时间是1969到1973年。C语言基于CPL（混合编程语言，译注：Combined Programming Language是早期的一种计算机编程语言，由剑桥大学数学实验室和伦敦大学计算机研究室联合开发的）,人们将CPL语言的特性融入到B语言中（译注：即后来的BCLP语言），美国计算机科学家Ken Thompson后来称B为计算机编程语言；Ken�

用linux C 下的函数调用创建中文目录、文件等，字符串的编码格式要求是utf-8格式的。
比如想要使用 int mkdir(const char *pathname, mode_t mode); 创建一个中文的目录。那么pathname的编码格式要求是utf-8的，而不能是gb3212/gbk的，否则就是乱码。
那么如果linux C下如何进行gbk<---->utf-8编码转换的编码装换的 ......
Boss说，要看OpenGL，看了快一个月，总算出了个像样的东西，用C写了个3D迷宫，

指针是C的灵魂，正是指针使得C存在了这么多年，而且将长期存在下去。事实上，我自己不用C语言写程序已经有一年了，工作中接触到的只有java，python和javascript.最近用C完成了一下类似于OO中的封装（即"类"）的概念，顺便把指针复习了下，感觉有必要记一下。
本文中的例子有这样两个概念：任务（Task） ......
C语言中可变参数的用法
我们在C语言编程中会遇到一些参数个数可变的函数,例如printf()
这个函数,它的定义是这样的:
int printf( const char* format, ...);
它除了有一个参数format固定以外,后面跟的参数的个数和类型是
可变的,例如我们可以有以下不同的调用方法:
printf("%d",i);
printf("%s",s);
printf( ......
