Char substring, not String substring

[J-M-L]

Yes

  char myChar[] {"123456789"};
  char subString[6] {'\0'};
  strncpy(subString, myChar+4, 2);

just a note to add that the '0' initialisation of the subString is important otherwise subString would likely not be properly terminated with the null char after the strncpy.
