I've worked with making classes, but I've never had to use a class in code that I write, so I'm having a hard time.

}my professor wrote most of the code up. i added the class heading at the top and thats about it. I cant get it to compile and I'm getting an errors that say:
hw7.cpp(34) : error C2040: 'String' : 'char [255]' differs in levels of indirection from 'String'
hw7.cpp(65) : error C2676: binary '[' : 'String' does not define this operator or a conversion to a type acceptable to the predefined operator
the class is called String2.cpp.
I dont know why its not compiling.
