[Ref: 2.2 of the Chapter 2 lecture notes - Representing Unsigned Integers] Background: The word size of a microprocessor is a term that refers to the number of bits, n, that are used in vari- ous places of the computing system, e.g., the sizes of the general-purpose registers, the width of the data bus, and pos- sibly the width of the address bus as well. Also, in a high-level language like C or C++, if the word size of a pro cessor is n-bits, integer values of the data types int/signed int and unsigned int will also be represented in n-bits (henceforth, understand that in C, the int and signed int data types are interchangeable, so we will just use the term int here to represent both int and signed int). In modern computing systems, n is always a power of 2 and is also a power of 8, so common microprocessor word sizes are 8-bits, 16-bits, 32-bits, 64-bits, and 128-bits. For this exercise, suppose the word size of our microprocessor is n = 16-bits
(b) In the C programming language, the C Standard Library contains a fle which defnes a constant which specifes the minimum value, in decimal, of an n-bit unsigned int. Let us call this constant UINT_MIN. What would be the decimal value of UINT_MIN for a C compiler designed to run on our 16-bit microprocessor system?
