Assignment: Problems given in assignment section should be submitted only.
Problem – 1 (Students Grade)
Write a program to calculate students’ average test scores and their grades. You may assume the following
input data:
Johnson 85 83 77 91 76
Aniston 80 90 95 93 48
Cooper 78 81 11 90 73
Gupta 92 83 30 69 87
Blair 23 45 96 38 59
Clark 60 85 45 39 67
Kennedy 77 31 52 74 83
Bronson 93 94 89 77 97
Sunny 79 85 28 93 82
Smith 85 72 49 75 63
All arrays must be created dynamically. Mentioned above file may contain any number of records.
Use three arrays: a one-dimensional array to store the students’ names, a (parallel) two-dimensional array
to store the test scores, and a parallel one-dimensional array to store grades. Your program must contain
at least the following functions: a function to read and store data into two arrays, a function to calculate
the average test score and grade, and a function to output the results. Have your program also output the
class average.
Problem – 2 (Library Summary)
Create a library fine summary program. You will read a file of library patron data containing a library
patron number, an item (book, movie, music) number, and a fine amount. At most, there will be five
library patrons in the file. You will produce a summary report that lists the total fines for all of the patrons
in the input file.

MV <Fine Sub Total of all MV Patrons>
AR <Fine Sub Total of all AR Patrons>
NS <Fine Sub Total of all NS Patrons>
--------------------------------------------
Total <Total of All patrons>
Problem – 3 (Local Elections)
Write a program that reads the names of candidates in a local election and the number of votes received
by each candidate from a file. The program should then output each candidate’s name, the number of
votes received, and the percentage of the total votes received by the candidate.
[Hint: Use Dynamic Array only. Create one array to store names, a 2D array to store votes and calculated
percentage. All functions with pointer/pointer arrays]
Your program should also output the winner of the election. A sample output is:
Candidate Votes Received % of Total Votes
Waleed Azhar 5000 25.91
Tamur Fazal 4000 20.73
Hamza Abbas 6000 31.09
Tayyab Rehman 2500 12.95
Waqas Ahmed 1800 9.33
---------------------------------------------------------
Total 19300
---------------------------------------------------------
The Winner of the Election is Hamza Abbas.
