                                    C++ is a general-purpose programming language created by Bjarne 
Stroustrup as an extension of the C programming language, or 
&quot;C with Classes&quot;.

//as you can also see to your right ----------------------&gt;

C++ still qualifies as a high-level languge, yet the rise of 
languages like Ruby and Java have given capabilities that sway
people's opinion towards what is and is not &quot;high-level&quot;. 

Yet high-level simply means it's farther from machine code and closer 
to human-readable form. Hence the need for a compiler/interpreter.

So don't get too worked up about granular specifics.

                                    C++ is a high-level, general-purpose programming language.

//totally not right there -----------------------------------&gt;
