# A teacher needs a program to record marks for a class of 30 students who have sat three computer
# science tests.

# Write and test a program for the teacher.
#     - Your program must include appropriate prompts for the entry of data.
#     - Error messages and other output need to be set out clearly and understandably.
#     - All variables, constants and other identifiers must have meaningful names.

# You will need to complete these three tasks. Each task must be fully tested.


# TASK 1 – Set up arrays

# Set-up one dimensional arrays to store:
#     - Student names
#     - Student marks for Test 1, Test 2 and Test 3
#         - Test 1 is out of 20 marks
#         - Test 2 is out of 25 marks
#         - Test 3 is out of 35 marks

# Input and store the names for 30 students. You may assume that the students’ names are unique.

# Input and store the students’ marks for Test 1, Test 2 and Test 3. All the marks must be validated on
# entry and any invalid marks rejected.
