Hi again everybody,
I am having a bit of trouble in getting this script to work properly. Two error messages are coming up when I compile this code. They are as follow:
1) Error 1 error C2664: 'fillArray' : cannot convert parameter 3 from 'int [50]' to 'int &' f:\My Documents\Visual Studio 2005\Projects\Final Using Arrays\Final Using Arrays\Final Using arrays.cpp 49
2) Error 2 error C2440: '=' : cannot convert from 'std::string' to 'char' f:\My Documents\Visual Studio 2005\Projects\Final Using Arrays\Final Using Arrays\Final Using arrays.cpp 168
The problem is occurring when I am trying to store a name (which is gotten inside of the function "fillArray", inside of an Array which is located inside ofthe main function. I am sure it is a coding error (it usually is with me) and I really appreciate the help, this is only my first semester of study in the C++ language. Anyway here is the code. The Error are on line 49 and 168 Respectively. (They are labeled)
