<p>
The runtime_error family of classes are derived from the exception class.
There are three classes derived from <i>runtime_error;</i> <i>range_error</i>,
<i>overflow_error, and underflow_error</i>. The runtime_error classes report
internal computation or arithmetic errors. The functionality of the runtime_error
classes is similar to the logic_error classes. The runtime_error classes get their
primary functionality from their exception class ancestor. The what(), assignment
operator=(), and the constructors for the exception class provide the capability
of the runtime_error classes. Like the logic_error classes, the runtime_error classes
provide an exception framework and architectural blueprint to build upon. They provide
very little functionality unless the programmer specializes them through inheritance
or by including them in an interface class.

Access Public
Classification Constructor
Syntax runtime_error(const string &What_Arg)
Parameters The What_Arg parameter should contain a description of the kind of exception
that has occurred.
Return None
</pre>
<h3>Description</h3>
<p>
The runtime_error() method constructs an object of type runtime_error. The What_Arg parameter
can be used to set a description of the kind of error that this exception represents.
A set possible solutions is sometimes supplied with the exception description in addition
to the type of error.
