Question 21 O pts EXTRA CREDIT (up to 5 points): Recall that, in binary, negative numbers are represented using two's complement representation. If you were to declare an unsigned char variable in C and initialize it to -3, what would its value be? (Hint: The important word here is unsigned! Remember that, in C, a char is simply a one-byte number, and that the most significant bit of an unsigned number is treated as an ordinary bit and not as a sign bit. Enter your answer as an unsigned decimal number, without quotes or other symbols.)
