VC2005绿色编译器--命令行下编译C++代码

有人学了三个月没写过helloworld;有人不知道编译器是什么;有人第一个helloworld编译一下,数百个ERROR,自信心失去一大半.
学习c++,想试验一下习题,不知道如何入手,你还在IDE里面重复新建工程,然后产生一大片垃圾文件吗.
其实还有另外一种编译方式:
那就是传说中的记事本加命令行编译.只要你有U盘,只有装windows的电脑,就可以写代码了.

一.首先你要有Platform SDK
WIN7 Windows SDKS微软官方下载页

1.GRMSDK_EN_DVD.iso X86(32bit)

2.GRMSDKIAI_EN_DVD.iso I64(Itanium)

3.GRMSDKX_EN_DVD.iso AMD64(64bit)
二.安装完,然后在安装的根目录(含有PlatformSDK,lib,include目录)下新建一个cmd文件内容如下 (以VC8.0为例)

@echo off
@prompt $h
@title NewVS2005SP1-C/C++MODE
color f5if "#%vc2005dir_defined%"=="#" (set vc2005dir=%cd%&& set vc2005dir_defined=true)
if "#%path0_defined%"=="#" (set path0=%path% && set path0_defined=true )  @echo.
@echo    ******** 欢迎进入C/C++编译模式**********

rem 设置调试符号路径
@set  _NT_SYMBOL_PATH=%vc2005dir%\myTOOL\windbg\symbols
@echo VC2005所在根目录是%vc2005dir%
@echo (若上面目录不正确将不能正确配置环境变量path,include,lib)
@echo 请以 cd /d 命令转至源程序目录,然后开始编译等工作
echo.
PROMPT -
if "#%once_defined%"=="#" ( set once_defined=true&&%comspec% /k)

运行效果是这样子的

敲入CL /? LINK /?确定是否正确

3.每次敲命令是不是很烦,应该还有另一种方式生成目标,新建一文档Create_VC_UNICODE_v2.0.CMD,然后添加VC路径
if exist D:\software\DevKit\VC set vc2005dir=D:\software\DevKit\VC

@title VC8.0命令行生成WIN32,UNICODE,RELEASE版

到此我们就可以编译helloworld.cpp了

#include <iostream>
using namespace std;
int main()
{cout<<"hellowrold"<<endl;
}

将源文件单独放在新建的目录下,把Create_VC_UNICODE_v2.0.CMD也拷进入,双击CMD自动生成

再来个示例代码

//C++数值类型的取值范围
#include "stdio.h"
#include "iostream"
using namespace std;
int main()
{char a1=-128;//-128~+127
