Very Computer

> I made a simple application that is working on AIX machine. It's very

> In my source, I used the variables of char , signed char and unsigned char

>  main ()
> {
>       char a;
>       signed char b:
>      unsigned char c:

>     a = -1;
>    b = -1;
>    c = -1;

>    printf (" %d %d %d\n", a, b, c);

> }

> The result is :

> $ 255  -1  255

> Looking for the above result, In this case, I found char type is unsigned
> char type defaultly.
> For Integer variable, I did the same test. The result was same.
