# Answer to Question #8914 in C# for khuli

Question #8914

Your lecture wishes to store the exam marks for java,and perform an analysis of the marks.The marks are expressed as a percentage.There are 15 students that wrote the exam. Write the java program that will enable her to:

-input the marks for each student and store in an array called Supp.The input must be validated befoe being stored

-Determine and display the highest and lowest mark.

-Determine and display the average mark for the supplementary exam.

-Determine and display the mean and median(mean is calculated as the average of the lowest and highest marks)

E.g input:15 27 38 2 98 42 87 92 99 13 5 72 67 2 1

Output:

highest:99

lowest:1

median:38

average:44

mean:50

i'd be grateful for your help.

NB: URGENT!
