Your [] is in the incorrect place in all your functions, it goes after the name of the variable.
tomwadek (14)
do you mean something some thing like this
int sequentialSearch(StudentRecord records [], int numRecords, int studentID)
i changed them all, still getting same 3 error message

firedraco (6243)
Hm. Is this all in one file or in different files?
tomwadek (14)
all the same file
firedraco (6243)
On your sequential search you are missing an int on the last argument.

I think you are missing a } near the return 0; I can't tell because the indentation isn't very good though. If you fix it it will probably be easy to see.
