#include <iostream>
using namespace std;

n >=1;

cout<< "please enter an interger number:" <<endl;
cin >> n;

if(n == 9)

cout << "IX";

else if(n >=5 && n<=8)

It says

10 - X
50 - L
100 - C
500 - D
1000 - M

and second thing to notice is

20 = XX
30 = XXX
40 = XL

60 = LX
70 = LXX
80 = LXXX
90 = XC

and numbers from 1 to 9 just use I,II,III, .. with a prefix
like 20 = XX
and 21 = "XX"+ "I"


so .. get the number as a factor of 10 first .. and see to which group it belongs (using ifs.. etc)

Need to store:
I,II,III... IX
and
X,L,C,D,M
