namespace std {

}The class
runtime_error
defines the type of objects thrown as exceptions to report errors presumably detectable only
when the program executes
.runtime_error(const string& what_arg);
Effects:
Constructs an object of class
runtime_error. Postconditions:
strcmp(what(), what_arg.c_str()) == 0. runtime_error(const char* what_arg);
