A Char * var used with math operators... what is ?

[tonnot]

From c++ tutorial :

1 2 3 4

char str[] = "This is a sample string"; char * pch; pch=strrchr(str,'s'); cout<<pch;

cout<<str; --- This is a sample string cout<<pch-str+1;

When do pch-str+1, we are working with pointers?


But cout<<pch; give me 'string'.
This is the normal behavior of char types?
Thanks

Both str and pch are actually pointers to char.
Pointers to chars are interpreted as null-terminated strings in output operations
