This function reads an entire line from stream, storing the text (including the newline and a terminating null character) in a buffer and storing the buffer address in *lineptr. Before calling getline, you should place in *lineptr the address of a buffer *n bytes long, allocated with mall...

例如,重载 func(const pair<int, int>&) 和func(const pair<string, string>&),并使用 func() 调用pair<const char *, const char *>,将使用此更改进行编译。 但是,此更改会中断依赖主动对转换的代码。 通常可以通过显式执行部分转换来修复这些代码,例如,将 make_pair(static_cast<B>(a), x) 传递给...
