    Why not strcpy?

    This works

    Code:
    	char a[]="Sorensen";
    	char b[256];
    	int i=0;
    	while(b[i++]=a[i])
    		;

    Ok -

    Code:
    	char* a="Sorensen";
    	char b[256];
    	char* c=b;
    	while(*c++=*a++)
    		;

    Mmmm would you need to add a line which places a '\0' at the end of the new string?

    No, because the '\0' will be assigned and then the while loop stops because *c contains '\0'. It's checking the target string not the source.
