  1. char* convertFromDecimal(int num, int toBase) {
  2.     char chars[] = { "0123456789ABCDEFGHIJ" };
  3.     char *result;
  4.     char digit[] = { '\0', '\0' };
  5.     char temp[RESERVE_CHARS];
  6.     memset(temp, 0, sizeof temp);
  7.     result = (char*)calloc(RESERVE_CHARS, sizeof(char));
  8.     memset(result, 0, sizeof result);
  9.  
  10.     int over;
  11.     while (num > 0) {
  12.         over = num % toBase;
  13.         digit[0] = chars[over];
  14.         strcat(temp, digit);
  15.         num /= toBase;
  16.     }
  17.  
  18.     /* reverse the temp string to get real digit */
  19.     int p, x;
  20.     for ( p = strlen(temp)-1, x=0; p >= 0; --p, ++x) {
  21.         result[x] = temp[p];
  22.     }
