Percentile program in c++

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



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%.

int a[10],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<<" Enter Marks for"< 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"< }
getch();
