Did you ever notice how so much of the code you read in books and on the wbe indents lines? It's for a good reason. I have indented some of your code. See if you can spot the problem now. Take a look at the way each { is lined up with a }.

What do the errors say?
Dash (126)
What are the errors? Why is it all commented out, it just makes it harder to read.
jeff99577 (21)
i have commented out and now getting error of multiple definitions of ROWS.
jeff99577 (21)
now i have an issue with my global variables. do i #include "header.h" in function.cpp? have made header.h properly

jeff99577 (21)
thanks i did it but still error
coder777 (8444)
What are the exact words of the(se) error(s). Or should be still guess...
jeff99577 (21)
[build error] [project1] error 1.
it has to do with inFile. probably how i am reading into a two dimensional array. i am trying to read mutiple words into 2D array.
coder777 (8444)
if that's the only output of the compiler/linker -> get another one.

Where are all those globals (shudder) defined? (Hint: it must be in a *.cpp)
jeff99577 (21)
nice comment coder. i have been at it for awhile.

On line 11: remove extern. constants can't be extern


It si a wrong statement. Constants as any other variables may be declared with the storage-class specifier extern.

The problem of the code is not that the declaration of the constant has the storage-class specifier extern. The problem is that one entity that is the constant defined several times.

figured it out
const unsigned int ROWS_2D = 20;
i knew it was calling it more than once. know i know the "unsigned" prevents a multiple decloration.
