| 晕，一个简简单单的C++程序，编译那么多警告错误？？？ |
程序： #include <iostream> #include <fstream> #include <string> #include <map> #pragma warning (disable : 4786) #pragma warning (disable : 4086) using namespace std; int main(char *argv[], int argc) {

在VC下~我也遇到过这种情况~~在代码无错的情况下~~能运行~~你试试 |

vc6 一大堆警告,vs2003 风平浪静. 为什么呢? 关注! |
| whyglinux(山青水秀) 于 2005-5-12 17:18:24 |
把 #pragma warning (disable : 4786) #pragma warning (disable : 4086) 放到文件的开始处。 |
| djfu(一马平川) 于 2005-5-12 17:18:38 |
很多人说是因为 VC6 与标准不兼容？ |
| xyz_mw(abc) 于 2005-5-12 17:20:39 |
vc6的问题 |

#pragma warning (disable : 4786) #pragma warning (disable : 4086) 放到文件的开始处 ______________________________________ 可以了,为什么? |
| djfu(一马平川) 于 2005-5-12 17:24:38 |
whyglinux(山青水秀) 你的方法不错，果然可以消除了。 |
| BugYou004 于 2005-5-12 17:29:35 |
嘿嘿！！ 长见识啦 |
| ericqxg007(一笑而过) 于 2005-5-12 19:07:42 |
我想知道这是为什么？ |
| guyaguya(我只愿面朝大海，春暖花开) 于 2005-5-12 20:16:28 |
搜下 pragma的用法就知道为什么了 |
