help please!

can someone help me figure out why my output is incorrect any help would be apprecaited

It would help if you posted the output you were supposed to have and what output you got

[StuXYZ]

First off, you cannot write fractions fractions :: operator/(fractions f); within the definition of a class.

Second, you have provided a default constructor that set the fraction to 0/1 . That gives perfectly acceptable results. So which test is wrong??

Third: You have not used references in many of your function , so there is lots of unnecessary copying

Forth: The biggest failing the the lack of code reuse. You have addFraction and operator+ using the smae code. PLEASE call one with the other. Otherwize you have two places to change each time and that leads to a mess.

It would help if you posted the output you were supposed to have and what output you got

the output im getting is

Please enter numerator2
Please enter denominator4
10/8
28/16
-2/8
-12/16
24/8
384/16
6/8
1/16
Press any key to continue . . .

its suppose to add subtract mulitplty etc fractions

Also see my post in your other thread about the flaw in your multiplication...

Stu, I'm thinking having 2 functions (one operator and one non-operator) might have been part of the assignment.
