1 设置GCC命令行使用环境变量：
SET GCC_HOME=E:/MinGW
SET PATH=%PATH%;GCC_HOME
SET LIBRARY_PATH=%GCC_HOME%/lib
SET C_INCLUDE_PATH=%GCC_HOME%/include
SET CPLUS_INCLUDE_PATH=%GCC_HOME%/include/c++/3.4.2;%GCC_HOME%/include/c++/3.4.2/mingw32;%GCC_HOME%/include/c++/3.4.2/backward;%GCC_HOME%/include

2 Demo.c
#include <stdio.h>
int main()
{
 printf("%6d",10);
 printf("|/n");
 printf("%-6d",10);
 printf("|/n");
 printf("%0.6d",10);
 printf("|/n");
 printf("%7.6d",10);
 printf("|/n");
 printf("%-7.6d",10);
 printf("|/n");
 return 0;
}

编译gcc -o demo.exe Demo.c
测试：demo.exe

3 Demo.cpp
#include <iostream>

int main(int argc, char* argv[])
{
 std::cout << "Hello world./nBye.";
 return 0;
}

编译：c++ -o demo.exe Demo.cpp
测试:demo.exe
