1 Error Message

[simon126]

Please help i am getting an error message when i try to complie my program. It gives me this error rror C2664: 'output_calculations' : cannot convert parameter 1 from 'double (double,double)' to 'double' Context does not allow for disambiguation of overloaded function.

I have not the slightest clue what this means please help.

Perhaps it means that you intermingle hat_size as both the name of a variable and a function and the compiler is trying to figure out which one you mean in any particular context. You tell it a couple things and expect it to know which one you mean.
