如何在命令行下编译创建VC程序

转贴自常州VC编程网http://www.czvc.com/down.asp?id=94
大多数MS Visual C++创建的程序用VC编译器是很容易编译并创建出可执行文件的。但有时，你可能需要从命令提示行运行程序。这个例子将阐述如何用命令行编译创建VC程序。

VC默认安装成功后，并不具备能从命令行编译创建VC程序这一特征。我们必须做如下3步工作：

1 打开DOS命令提示符窗口。

2 在C盘根目录下输入：
CD Program Files/Microsoft Visual Studio/VC98/Bin
回车进入到如下目录：
C:/Program Files/Microsoft Visual Studio/VC98/Bin>

3 然后输入VCVARS32再回车，你可以看到如下信息：
C:/Program Files/Microsoft Visual Studio/VC98/Bin>VCVARS32
Setting environment for using Microsoft Visual C++ tools.
如图1：

好了，至此相关设置完成，接下来我们将在命令行下编译创建一个VC程序：

1 打开VC，选择NEW，在工程属性页选择“Win32 Console Application”，这里我把它命名为AConsoleApp，
我的工程目录为：D:/MyProgram2/AConsoleApp，然后OK创建一个空的Win32控制台工程。

2 新建一个C++文档main.cpp,输入如下代码：
#include
using namespace std;

int main()
{
cout << "/nC++ is Fun!!!/n";
return 0;
}
保存所有文档，关闭工程。

3 打开DOS命令提示符窗口，使当前目录为D:/MyProgram2/AConsoleApp>,然后输入CL main.cpp，回车，可以看到如下信息：
D:/MyProgram2/AConsoleApp>CL main.cpp

/out:main.exe
main.obj

D:/MyProgram2/AConsoleApp>


此时你可以发现目录D:/MyProgram2/AConsoleApp>下已经生成了可执行文件main.exe，您可以在命令行环境下执行它，输入main并回车，结果如下：
D:/MyProgram2/AConsoleApp>main

C++ is Fun!!!
