Problem 4 (C Arithmetic) We are running programs on a machine with the following characteristics: Values of type int are 32 bits. They are represented in twos complements, and they are right-shifted arithmetically. Values of type unsigned are 32 bits. Values of type float are represented using the 32-bit IEEE floating point format, while values of type double use the 64-bit IEEE floating point format. We generate arbitrary values x, y, and z and convert them to other forms as follows:

/* Create some arbitrary values */ int x = random(); int y = random(); int z = random(); /* Convert to other forms */ unsigned ux = (unsigned) x; unsigned uy = (unsigned) y; double dx = (double) x; double dy = (double) y; double dz = (double) z; For each of the following C expressions, you are to indicate whether the expression always yields true. If so, circle Y. If not, circle N. Provide an example if your answer is N.
