] | If I have:
```
signed char * p;
```
and I do a comparison:
```
if ( *p == 0xFF )
break;
```
it will never catch 0XFF, but if I replace it with -1 it will:
```
if ( *p == (signed char)0xFF )
break;
```
How can this happen? Is it something with the sign flag? I though that `0xFF == -1 == 255`. | The value `0xFF` is a signed int value. C will promote the `*p` to an `int` when doing the comparison, so the first if statement is equivalent to:
```
if( -1 == 255 ) break;
```
which is of course false. By using `(signed char)0xFF` the statement is equivalent to:
```
if( -1 == -1 ) break;
```
which works as you ... |
