Description
html markup
shown to student

Add a member function to allow a Complex number (object) to be added with an integer.
<p>
Example:
<pre>
Complex c1(2,3);
Complex c2 = c1 + 6; // should yield 8+3i
</pre>

e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]
