   [Solved]substr() for char *
  Is there a function similar to the Cstring substr() function for char * ??This is what the function should do:subchar(const char *  , start,length) //prototypereturn a substring fromchar * start at position <start> and with the length <length>example:char * temp="test";char * temp2 = subchar(temp,1,2);printf(temp2);does a similar function exist in c++ for char *??[Edited by - Aidamina on December 3, 2005 6:10:57 AM]
  std::string(temp).substr(pos,length);   ;  I assume you're using plain C:const char temp[] = "test";const char substring[10] = { 0 };strncpy(substring, &temp[1], 2)printf(substring);If you're using C++ then Trap's solution is the best.   ;  std::string(temp+start, length)   ;Quote:Original post by ZQJstd::string(temp+start, length)That's a bit faster than my version, especially if you only need a small part of the string and it works with char* that are not properly \0-terminated.   ;Quote:Original post by ZQJstd::string(temp+start, length)Just had a thought - if temp is not NULL terminated then the string MUST be longer than start+length; if it is NULL terminated the string must be longer than start otherwise this will break, where Trap's version won't.   ;  Thx for the info
