strcpy question
PostPosted: Tue Jun 29, 2004 4:01 am     Reply with quote

Is strcpy function in string.h correct ?
It seems that it doesn't copy the '\0' too in destination string:
s2 is {'h','e','l','l','o','\0'} and s1 is {'1','1','1','1','1','1'}
after strcpy(s1,s2), s1 is {'h','e','l','l','o','1'} and not {'h','e','l','l','o','\0'}.

Is it right ?

I think there are some mis-understandings. I think s1 and s2 should have the same length. With the strings given strlen() function should return 5 for s2 and 6 for s1. Try with the example given in CCS help (look for STRLEN). It is not possible to do a=strlen("hello"); you must use arrays.

Best wishes.

Paolo.

It looks like a bug to me.

In v3.187 this is the code from string.h for strcpy():
Code:
/*    Standard template: char *strcpy(char *s1, const char *s2)
copies the string s2 including the null character to s1*/

char *strcpy(char *s1, char *s2)
{
  char *s;

  for (s = s1; *s2 != 0; s++, s2++)
     *s = *s2;
  return(s1);
}


According to the comment (and the ANSII standard) the nul character is too be copied, but it isn't.....
