Re: Help Code won't compile

I have been working with this code for a better part of the day and I
can't figure out where I am making a mistake. I can only imagine it
is when I declare multiple paramaters on the constructor because the
program compiles with just one parameter. Can someone look at this
and tell me where I made my error?

This is the error I get while trying to compile.

error C2664: 'GradeBook::GradeBook(const GradeBook &)' : cannot
convert parameter 1 from 'const char [38]' to 'const GradeBook &'

Reason: cannot convert from 'const char [38]' to 'const GradeBook'

No constructor could take the source type, or constructor overload
resolution was ambiguous

Thanks
