1 設定GCC指令行使用環境變量：

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 &lt;stdio.h&gt;

int main()

{

 printf("%6d",10);

 printf("|/n");

 printf("%-6d",10);

 printf("%0.6d",10);

 printf("%7.6d",10);

 printf("%-7.6d",10);

 return 0;

}

編譯gcc -o demo.exe Demo.c

測試：demo.exe

3 Demo.cpp

#include &lt;iostream&gt;

int main(int argc, char* argv[])

 std::cout &lt;&lt; "Hello world./nBye.";

編譯：c++ -o demo.exe Demo.cpp

測試:demo.exe
