std::ios_base::failure 是C++ 标准库中的一个异常类,它继承自 std::exception。这个异常类专门用于表示与输入/输出(I/O)流操作相关的错误。当 I/O 操作失败时,如文件无法打开、读写错误等,std::ios_base::failure 异常会被抛出。 描述std::ios_base::failure通常在什么情况下被抛出: std...

除了上述的标准异常类外,C++ 标准库还提供了其他一些异常类,如 std::ios_base::failure 用于表示 I/O 操作失败等。 这些标准异常类可以直接使用,也可以作为用户自定义异常类的基类来扩展功能。在异常处理时,通常会捕获特定类型的异常并相应地处理,以提高程序的健壮性和可靠性。
