说明：  Linux系统下的Gcc（GNU C Compiler）是GNU推出的功能强大、性能优越的多平台编译器，是GNU的代表作品之一。gcc是可以在多种硬体平台上编译出可执行程序的超级编译器，其执行效率与一般的编译器相比平均效率要高20 ~30 。 Gcc编译器能将C、C++语言源程序、汇程式化序和目标程序编译、连接成可执行文件，如果没有给出可执行文件的名字，gcc将生成一个名为a.out的文件。在Linux系统中，可执行文件没有统一的后缀，系统从文件的属性来区分可执行文件和不可执行文件。而gcc则通过后缀来区别输入文件的类别，下面我们来介绍gcc所遵循的部分约定规则
(Linux systems for Gcc (GNU C Compiler) is GNU launched a powerful, superior performance, multi-platform compiler, is one of GNU s representative works. gcc is available in a variety of hardware platforms, compile the executable super compiler, the implementation of the efficiency and general efficiency of the compiler average higher than 20 to 30 . Gcc compiler can C, C++ language source program, Health and programmable sequence and the target program compiled, linked into an executable file, if not give the name of the executable file, gcc will generate a file named a.out. In Linux systems, the executable file suffix is not a unified system to distinguish between the properties from the file executable files and can not execute the file. The gcc through the input file suffix to distinguish between the categories, let s introduce some gcc followed the rules agreed upon)
