I am a programmer in learning and i have a problem.

I use visual studio 2015 and in language 'C' i have to make a program which entered array of char's sorts into ascending order, prints out only Roman numerals out of it ('I','X','V'...) and an array without those numerals. Total of 3 prints. I would really appreciate if someone would write down the code since i tried many times and failed to make it. Also try using only for's and if's since i can use those only .

Code example:

Code:
#include <stdio.h>  
#define MAX_BR_EL 15
void main()
{
 int i, p, j, s, n;
 while (1) {
    printf("Enter the array length:\n");
    scanf("%d", &n);
    if (n <= 0 || n > MAX_BR_EL) break;
    char a[n];
    printf("Enter the array:\n");
    for (s = 0; s < n; scanf("%c", &a[s++]));
    {
        for (i = 0; i < n - 1; i++)
            for (j = i + 1; j < n; j++)
                if (a[i] < a[j]) { p = a[j], a[j] = a[i], a[i] = p; }
    }
        printf("Arranged array:\n", a[s]);
    }
    if (a[s] == 'I' || a[s] == 'V' || a[s] == 'X' || a[s] == 'L' || a[s] == 'C' || a[s] == 'D' || a[s] == 'M')
    {
        printf("Array of Roman numerals:\n");
        printf("%c\n", a[s]);
    }
    else
    {
        printf("Array without Roman numerals:\n");
        printf("%c\n", a[s]);
    }


 }
