### To calculate percentile

``` To calculate percentile 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%. #include<iostream.h> #include<conio.h> void main() { clrscr(); int a,n,i,j; int percent; int count; cout<<" enter the size of array"; cin>>n; cout<<" enter the values"; for(i=0;i<=n-1;i++) { cout<<" a["<<i<<"]"<<"="; cin>>a[i]; } for( i=0;i<=n-1;i++) { count=0; for(j=0;j<=n-1;j++) { if(a[i]>a[j]) { count=count+1; } } percent=(count*100)/(n-1); cout<<" the percentile of"<<"a["<<i<<"]"<<percent; } getch(); } ```
