<div class="content wysiwyg-content">
I have this recursive function again.<br />
long gcd (long x, long y)<br />
{ <br />
&nbsp; &nbsp;return (x==0L) ? y : gcd( y % x,x);<br />
}<br />
this is supposed to keep fractions in the lowest terms.<br />
it works fine for addition and subtraction<br />
how can I use it for multiplication and division.<br />
I have always multiplied fractions like this<br />
a/b *c/d = a *c / b*d<br />
how can I use the gcd to reduce<br />
thanks in advance.<br />

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.
