C++ fraction program problem?

C++ fraction program problem?
I really am sorry, because this is so easy but I don't have the time to go through it all. As far as printing out the input numbers, thats easy. Right after you input the number with cin%26gt;%26gt;.... do this:





out%26lt;%26lt;fra.num%26lt;%26lt;frac%26lt;%26lt;fra.den; // 1st fraction





if you want the whole expression, take the cin%26gt;%26gt; and just put out%26lt;%26lt; with '%26lt;%26lt;' changed for '%26gt;%26gt;'.





out%26lt;%26lt;fra.num %26lt;%26lt;frac %26lt;%26lt;fra.den %26lt;%26lt;oper %26lt;%26lt;fra2.num %26lt;%26lt;frac2 %26lt;%26lt;fra2.den;








Don't try to write the entire program at once and then run it. You should be writing things step by step, and running the partial program to test. It makes it so much easier to know where the mistakes are, rather than having to go back through everything anytime it fails.
Reply:i don't know.
