## Detailed Description

One of two subclasses of exception.

Runtime errors represent problems outside the scope of a program; they cannot be easily predicted and can generally only be caught as the program executes.

## Member Function Documentation

## ◆ what()

virtual const char * std::runtime_error::what | ( |  | ) | const
| virtualnoexcept

Returns a C-style character string describing the general cause of the current error (the same string passed to the ctor).

Reimplemented from std::exception.

Reimplemented in std::experimental::filesystem::v1::filesystem_error, std::filesystem::filesystem_error, and std::ios_base::failure.
