TYPE StudentResult DECLARE LastName : STRING DECLARE FirstName : STRING DECLARE ExamGrade : STRING ENDTYPE If any grades are missing in CurrentResults.dat, the text "Missing grade" is added to the ExamGrade field in StoredResults.dat Complete this file handling pseudocode algorithm. DECLARE Grade : StudentResult DECLARE Position : INTEGER OPENFILE "StoredResults.dat" FOR RANDOM SEEK "CurrentResults.dat", Position GETRECORD "CurrentResults.dat", Grade IF Grade.ExamGrade = "" THEN ENDIF NEXT Position CLOSEFILE "CurrentResults.dat" CLOSEFILE "StoredResults.dat"
