gcc在编译c语言的实现
------简单语法
#gcc cu.c -o cu
#./cu
结果:hello world
其中:用gcc对源文件进行编译和连接,-o指定可执行文件的名称．
也可以这样：
#gcc cu.c
#./a.out
结果:hello world
上述过程看似简单但是gcc的工作远比这复杂，在执行过程中要：预处理、编译、汇编、连接、都是在gcc后台完成的。首先，gcc运行预处理程序cpp，展开成cu.c中的宏，并在其中插入#include文件所包含的内容，然后把预处理后的源代码变成目标代码，最后通过连接程序创建可执行文件。通常可用gcc中的-E选项。
为了使其显示更准确地执行过程如下命令：
#gcc -E cu.c -o cu.cpp
经过预处理后，gcc会把cu.cpp编译成目标代码。这个过程用gcc的-c选项实现。
#gcc -x cpp-output -c cu.cpp -o cu.c
使用gcc可以将多个文件源文件进行编译成目标文件。
#gcc prt.c printf2.c -o hello
#./hello
