I guess you name &quot;reference&quot; to a pointer? That is:<br />
<br />
std::string *SomeFunction(arguments here)<br />
<br />
You can always return a NULL pointer if function fails, just<br />
<br />
(inside function)<br />
return NULL;<br />
<br />
(outside function)<br />
std::string *aString=SomeFunction(argu<wbr />ments here)<br />
<br />
if (aString!=NULL) {<br />
&nbsp; &nbsp; &nbsp;// some action here<br />
}

Convert blank string to reference

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
