Char substring, not String substring

Projects Programming

strncpy() only appears to give parameters for the length from the start of the char and not a start and end location.

I've found a work around, it's not pretty but it works.

  char myChar[10]="123456789";
  Serial.println();
  Serial.println(myChar);

  char subChar[4];
  String tempString=(String(myChar).substring(4, 6));
  tempString.toCharArray(subChar,sizeof(tempString));
  Serial.println(subChar);
