I need help getting my code to work in Mobaxterm in C++ with only tw.pdf

I need help getting my code to work in Mobaxterm in C++ with only two files being edited, both
under the name of Rational and I am trying to fix my one error. Please have a snapshot of your
output in Mobaxterm. I want the output to be exactly the same:
Output:
Handles zero over anything as 0 over 1
OK
Normalizes Rational(99,33) in the constructor.
OK
(1/3) * (100/1) = (100/3)
OK
(3/7) / (1/7) = (3/1)
OK
OK
OK
(1/3) + (2/5) = (11/15)
OK
(2/3) - (1/6) = (1/2)
OK
OK
(11/15) = (11/15) = (11/15)
OK
OK
0.73333333333
Code: That needs to be edited and fixed.
