If you just want to print the substrings      char s      THESTRINGHASNOSPACES   size t i  slen   strlen s   for  i   0  i  lt  slen  i    4      printf    4s n   s   i

If the task is only copying 4 characters  try for loops  If it s going to be more advanced and you re asking for a function  try strncpy   http   www cplusplus com reference clibrary cstring strncpy   strncpy sub1  baseString  4   strncpy sub1  baseString 4  4   strncpy sub1  baseString 8  4     or  for int i 0  i lt 4  i        sub1 i    baseString i   sub1 4    0  for int i 0  i lt 4  i        sub2 i    baseString i 4   sub2 4    0  for int i 0  i lt 4  i        sub3 i    baseString i 8   sub3 4    0    Prefer strncpy if possible
