Thread: strcpy command

please explain strcpy command !!!!!!!!

is the following a valid function ??

Code:

char *strcpy (char *End, char *Begin)

{  char *s, *t;
     
     s = Begin;
     t = End;

    while (s = '\0')
 
      { t = s;
         *s++;
         *t++;
       }

      t = '\0';
      return t;
}

I am guessing this function is just copying string from BEGIN to END using the strcpy command but not sure of
1) if the while loop is correct
2) what the deal is with saying t = '\0' wouldn't the loop end automatically when *t pointed to the NULL character??
3) do you return t or 0 ???
