因为有几个同学有同样的情况，就直接po在板上。 有同学反应程式在自己电脑可以编译，不过却没有分数并被标记以下的compile error: no matching function for call to 'std::pair<std::string&, CmdExec*>::pair(~~~) 我google了一下，找到了相关的问题 http://stackoverflow.com/questions/3769781/stdpair-of-references No, you cannot do this reliably in C++03, because the constructor of pair takes references to T, and creating a reference to a reference is not legal in C++03. Notice that I said "reliably". Some common compilers still in use do not allow forming a reference to a reference, but more recently do allow it as they implement reference collapsing (T& is T if T is a reference type). If your code uses such things, you cannot rely on it to work on other compilers until you try it and see. 因为惯用的所上Server的compiler版本gcc version 4.2.4，的确不允许这样使用， 我试着用gcc version 4.4.4，则就编译成功了。 故部分同学的分数已补回了。 不过因为基本上还是希望同学写的程式是 可以在一般平台上都能顺利编译(portability?)并正确运作(reliability?)的， 所以在Compile部分还是会酌扣一点分数! ===成绩更新=== bxxxx2x07 299 bxxxx2x22 105 --
