Passing dynamic array to function

weave (2)
I keep getting an error.
"Linker error: undefined reference to Readanswerkey(char*, int)"
Ultimately I'm going to read answerkey put it in a dynamic variable.
Following the answer key in the same input file will be test answers to compare to the key. I'm mainly trying to get the dynamic array to pass to the function.
Thanks in advance.


The input.txt file simply contains a series of T or F depending on the answer.

Your definition and prototype do not match for Readanswerkey.

Also please use code tags
