Question
Write a program to keeprecords and perform statistical analysis for a class of students.the class may have up to 40 students. there are five quizes during the term. Each student is identifiedby a four digit student number.
the program will print the student scores and calculate and printthe statistics for each quiz. the output is is in the same order asthe input
no sorting is needed. the input will be read from a text file. theoutput form the program should be similar to thefollowing.
student quiz1 quiz 2 quiz 3 quiz 4 quiz5 1234 78 83 87 91 86 2134 67 77 84 82 79 3124 77 89 93 87 71 high score 78 89 93 91 86 low score 67 77 84 82 71 Average 73.4 83 88.2 86.6 87.6 use one and two dimensional arrays only. Test your programwith these quiz data Student q1 q2 q3 q4 q5
