Hey , dude , I try that code out .. but this is not what I wanted.I wanted string a to be totaly replaced with string b without those 2 pluses.

Let's take an example , on your code :

Code:

#include <stdio.h>
#include <string.h>
main()
{
        char a[]="not working";
        char b[]="cool++";
        printf("a = %s \n", a);
        strncpy(a,b,strlen(b)-2);
        printf("a = %s \n", a);
        printf("b = %s \n",b);
        exit(0);
}

result :
a = not working
a = coolworking
b = cool++

The thing is , that I wanted , a become a="cool" , not a become "coolworking" .. totaly replace.In my first example strlen(!_30)==strlen(cool) .. my bad ..

P.S. : I hate C , on string processing .. Smilie

I made something , like , and it's working like I want ( maybe some users need this idea ).

Code:


#include <stdio.h>
#include <string.h>

int
main()
{

char a[]="now is working";
char b[]="cool++";
char bug[256];
int g;

printf("a = %s \n",a);

        for (g=0;g<strlen(b)-2;g++)
                      { bug[g]=b[g]; }
                       bug[g]='\0';
        stpcpy(a,bug);
        printf("a = %s \n",a);
exit(0);


        }

Result :

a="now is working"
a="cool".

     size_t
     strspn(const char *s1, const char *s2);

     char *
     strstr(const char *s1, const char *s2);

     char *
     strtok(char *restrict s1, const char *restrict s2);

DESCRIPTION

     The string functions manipulate strings that are terminated by a null byte.

     See the specific manual pages for more information.  For manipulating variable length generic objects as byte strings (without the null byte
     check), see bstring(3).

     Except as noted in their specific manual pages, the string functions do not test the destination for size limitations.

SEE ALSO

     bstring(3), index(3), rindex(3), stpcpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3), strcspn(3), strerror(3), strlen(3),
     strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

STANDARDS

     The strcat(), strncat(), strchr(), strrchr(), strcmp(), strncmp(), strcpy(), strncpy(), strerror(), strlen(), strpbrk(), strspn(), strcspn(),
     strstr(), and strtok() functions conform to ISO/IEC 9899:1990 (``ISO C90'').
