Konversi basis bilangan menggunakan rekursif

#include <stdio.h>
char ch[17] = “0123456789ABCDEF”;
void CetakBaseN(int base,int nilai)
{
if (nilai == 0) //jika nilai sudah 0 maka keluar
return;
CetakBaseN(base,nilai / base);
printf(“%c”,ch[nilai % base]);
}
void main(void)
{
CetakBaseN(2,255); printf(“\n”);
CetakBaseN(8,255); printf(“\n”);
CetakBaseN(10,255); printf(“\n”);
CetakBaseN(16,255); printf(“\n”);
}
