Casting 0xFF (char) to 255 (unsigned int)

If I have a char, "char c = 0xFF;", how do I "cast" it to 255 in an unsigned int?

"(unsigned int) c" gives me the 2's complement of 1, and "(int) c" gives -1.

Thanks!

EDIT:
this works, but looks very redundant...

Code:

---

unsigned int n = *((unsigned char *) &c);

---

Code:

---

char c = 0xFF;
unsigned u = (unsigned char)c;

---

Seems to work for me

Ah okay, that looks a lot nicer :).

Thanks

char is signed on most compilers, so (char)0xFF is -1. That's why the cast to the limited unsigned is necessary first.
