FILES OF RECORDS
Files can also contain records. Using read or write, it is possible to transfer a record at a time.

PROGRAM TWENTY_FIVE
Implement a Pascal program which allows the recalling of a group of student marks. The program is to output the highest and lowest marks, as well as the mean.

Use an array of records to store the names and marks. Using an output file, sort the student names, marks into ascending order, so that the student with the highest mark will be written first.

The details are,

     Student 1      Joe Bloggs      56
             2      Bill Anderson   24
             3      William Tell    78
             4      Bob Crane       23
             5      Peter Hall      57
             6      Charles French  76
             7      Bryan Goldwater 65
             8      Stewart Phelps  89
             9      Dave Stevens    78
            10      Ted Rosse       64

The student name consists of 16 characters, and the student mark is an integer in the range 0 to 100. Our example has a maximum of ten students.
