нужно преобразовать арабские цифры в римские
#include <iostream>
#include <math.h>
using namespace std;

{ case 1: coutint main(){
int n,m,p;
cin>>n; m=n/10; n%=10;
cin>>m; p=m/100; m%=100;
switch (m)<<"X";break;
case 2: cout<<"XX";break;
case 3: cout<<"XXX";break;
case 4: cout<<"XL";break;
case 5: cout<<"L";break;
case 6: cout<<"LX";break;
case 7: cout<<"LXX";break;
case 8: cout<<"LXXX";break;
case 9: cout<<"XC";break;
case 10: cout<<"C";break;
}
switch (n)
{
case 1: cout<<"I";break;
case 2: cout<<"II";break;
case 3: cout<<"III";break;
case 4: cout<<"IV";break;
case 5: cout<<"V";break;
case 6: cout<<"VI";break;
case 7: cout<<"VII";break;
case 8: cout<<"VIII";break;
case 9: cout<<"IX";break;
}
switch(p)
{
case 1: cout<<"CI";break;
case 2: cout<<"CC";break;
case 3: cout<<"CCC";break;
case 4: cout<<"D";break;
case 5: cout<<"DC";break;
case 6: cout<<"DCC";break;
case 7: cout<<"DCCC";break;
case 8: cout<<"CM";break;
case 9: cout<<"M";break;
}

return main();
}
