推荐答案

根据您的描述，您的代码没有行为问题……只是API怪癖，但您对此问题的解释可能不正确.

Based on your description, there is no behavior problem with your code... just API quirks, but your explanation of the issue may be incorrect.

无论哪种方式，如果您具有C ++ 11支持，则可以简单地编写此代码，而不必编写自己的手工函数，如注释中指出的那样:

Either way, if you have C++11 support, you could simply write this instead of your own hand-crafted function, as pointed out in the comments:

minExam = std::min({exam1, exam2, exam3, minExam});
