join 2 unsigned char

i needed to join 2 unsigned char as in

Code:

---


unsigned  short temp =  0x3e + 0x20 ;
// I do not want to add them
// resulting short should look like  0x3e20

---

One way is to use a left shift and then a bitwise or (or just add), but note that the result is unlikely to fit into an unsigned char (without changing its value).

Code:

---

unsigned  short temp =  (0x3e << 8) + 0x20;

---

thank you
