推荐答案

除了使用 sscanf 的最简单方法之外，例如

Aside from the easiest way with sscanf, like Jerry describes, it's also possible with iostreams. Just read the data you want from the file, until you hit a seperator, and discard that one into a dummy char:

char dummy;
myfile >> first_name >> last_name >> day >> dummy >> month >> dummy ... // and so on.
