我想实现以下代码。但是，我的MinGW / include目录中没有iostream.h。
我在网上找到了这个代码，我想用它来自动化我的实验室。
另一个问题，什么是.dsw文件以及如何让它继续运行？
谢谢！
/*
This program was written in Microsoft VC++ 6.0 Standard Edition. It demonstrates
use of SCPI commands to communicate with Keithley 2400 sourcemeter with GPIB interface.
It makes use of the CEC488 driver for Keithley GPIB cards: KPCI-488, KPC-488.2 or KPC-488.2AT
Please verify proper operation of the GPIB card by use of the TRTEST.exe utility program
located typically in the \Program Files\CEC488 folder. Use it to send *IDN? to the instrument
and then read back (enter command) 50 bytes from the instrument. If TRTEST.exe can
communiate with your SourceMeter, this program will work too.
Be sure to open the workspace file, 2400.dsw, to run this example.

答案 0 :(得分：0)
iostream应包含在您的编译器中。试试#include <iostream>
您可能还需要添加using namespace std
这可能对您有用：http://members.gamedev.net/sicrane/articles/iostream.html
