19.2.8 Class range_­error [range.error]

namespace std {
  class range_error : public runtime_error {
  public:
    explicit range_error(const string& what_arg);
    explicit range_error(const char* what_arg);
  };
}
The class range_­error defines the type of objects thrown as exceptions to report range errors in internal computations.
range_error(const string& what_arg);
Ensures: strcmp(what(), what_­arg.c_­str()) == 0.
range_error(const char* what_arg);
Ensures: strcmp(what(), what_­arg) == 0.
