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".
