I think the error messages are self explaining, you have problems with declarations and function arguments
Lisa (11)
Yes they do explain the prob but I am not sure how to fix it I change something then I get more errors so for instance the NumTests being undeclard how would I fix it to declare it should I put an f behind it that doesnt work or declare it in the identifiers I thought since it was a function parameter it didnt have to be listed as an identifier oh I don't know I'm just at a lost at this point.
Lisa (11)
I have made some changes and got rid of some errors yet I still have a few I can't figure out.

Only looking at syntax: line 33 shouldn't have a semicolon, line 45 has a random open brace, line 88's return statement should be below 89's curly brace
Lisa (11)
Okay the program will compile now with no errors but when I go to run it the program will not start??
