今天看做C++ primer的习题遇到getline输入string的变量时候需要两个回车才能结束输入，网上找了好久，原来是VC6的BUG，找到了解决的办法如下：
简单总结就是随便建立个C++的CPP文件 写个#include<string>,右击string在弹出框中选择打开文档<string>，然后点编辑工具栏-->点查找 ，在查找栏输入else if (_Tr::eq((_E)_C, _D))，点查找下一个，将下图的左边代码部分改成右边部分，保存后退出即可：
| original | modified |
| else if (_Tr::eq((_E)_C, _D)) {_Chg = true; _I.rdbuf()->snextc(); break; } |
else if (_Tr::eq((_E)_C, _D)) {_Chg = true; // _I.rdbuf()->snextc(); // (this comments out the defective instruction) _I.rdbuf()->sbumpc(); // corrected code break; } |
"getline" bug fix for Microsoft Visual C++ 6.0
If you are compiling using Microsoft Visual C++, Version 6.0, and you are using getline to read into a string object, you may notice that the user will need to press "enter" twice in order to continue on. This is a compiler bug.
In order to correct the "getline" bug in Microsoft Visual C++, Version 6.0 , carefully perform the following steps:
- Right click on the word string in the #include <string> in your header
- Choose open document string from the resulting pull down menu
- Click on Edit, then Find
- Enter the following line in the Search box:
else if (_Tr::eq((_E)_C, _D))
5.Make the following changes in code as shown:
| original | modified |
| else if (_Tr::eq((_E)_C, _D)) {_Chg = true; _I.rdbuf()->snextc(); break; } |
else if (_Tr::eq((_E)_C, _D)) {_Chg = true; // _I.rdbuf()->snextc(); // (this comments out the defective instruction) _I.rdbuf()->sbumpc(); // corrected code break; } |
- Save and close the string header file.
You should only have to do this once on your home PC. Unfortunately, if you want to do this in a student account, you may have to do this each time if you move to different machines, or if the machines have been re-imaged.
