Hard Assignment

[melorock]

"Create a class HugeInteger that uses a 40-element array of digits to store integers as large as 40 digits each. Provide member functions input, output, add, and subtract. For comparing HugeInteger objects, provide functions isEqualTo, isNotEqualTo, isGreaterThan, isLessThan, IsGreaterThanOrEqualTo, and isLessThanOrEqualTo - each of these is a "predicate" function that simply returns true if the relationship holds between the two HugeIntegers and returns false if the relationship does not hold. Also, provide a predicate function isZero."

Ok, my code is below. I tried to compile but I get 1 error stating "Expected unqualified-id before ":" token. I pointed out the line with the error in it.

I am sorry, but I am new to C++ and I'm not good at even basic programming. I viewed a lot of examples for this code and I do not fully understand everything I have done. So I ask please bear with me and please offer any help. Thank you

Remove the colon. It shouldn't be there in the first place.
