c++ rational class program
<p>please help help i dono why its not working  </p>

<p>aaahhhh....</p>

<p>such a pain</p>

<p>HELP help Help</p>

<p>please help me</p>

<p>problem is its not performaing any function now.. niether add nor subtract nor divison nor multiplication</p>

<p>any help will be apprecaited </p>

<p>thanks guys.... need explanation... so that i can understand it and get over with it :D</p>
