Getting the first 3 characters in C

Question

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 ?

Answer 1

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.

Answer 2

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.

Answer 3

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;
}

Answer 5

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 ...

Answer 6

The last 2 characters 😬
