Getting the first 3 characters in C

Hi, I wanna know if I have to use strcpy for getting the first 3 characters of a string ? Is there another way to do it or no ?

Considering you only want to copy 2 characters from source string, it's better to use strncpy() cause it allows us to specify how many characters are to be copied over. https://code.sololearn.com/cgj5BzZ6DIzu/?ref=app (Edited)

IMHO it's simplest to use strcpy() or strncpy(), cause those functions were meant for that purpose exactly. You can write your own, but that would probably be against the code-reuse concept.

Awe thank you so much , and also for getting the last two characters we have to use strcpy ? I've written this ,it works but I'm not sure if this is the optimized or no ? Int main() { Char mot[5],mot_trois_der[3]; Printf(" entrez votre mot : "); Gets(mot); Strcpy (mot_trois_der,mot); Printf("%s",mot); Printf("\n"); Return 0; }

Wait a minute, did you mean to copy first 2 characters or last 2 characters ... I had to ask cause your original post mentioned "first 3 character" in the title ...
