Write a program for the problem: the array of inetegers indicating the marks of the students is given, U have to calculate the percentile of the students aaccording to this rule: the percentile of a student is the %of no of student having marks less then him. For eg: suppose Student Marks A 12 B 60 C 80 D 71 E 30 F 45 percentile of C = 5/5 *100 = 100 (out of 5 students 5 are having marks less then him) percentile of B = 3/5*100 = 60% (out of 5, 3 have markses less then him) percentile of A = 0/5*100 = 0%.
