Im trying to add another feature to my primitive program :O) I was trying
to add a regular calculator allowing a choice from the quadratic equation
calculator and from a regular arithmetic calculator I keep getting two
errors which I marked in the code below Im still a beginner so I as if what
Im trying to do even possible if not can I have a program open either one
(each in its own executable) if so how? Thanks
Error summary
1. Parse error before else line 69
2. Parse error before } line 100
