Question 4 (10 points) 4. a) Suppose that char x and char y have values of 0xC4 and 0x71 respectively. Assume negative values are in 2's complement form. Enter the result of each of the following expressions: (Logical ops are &&, IL.: Bit-wise ops are &,l.) --[xly): Result = 0x A-x-y: Result=0x A (x&&y) (!x&&!y) : Enter O for false and 1 for true. Ax&&!y Enter O for false and 1 for true. A (X&OXOF) & (ly&OXOF)>>2) Result=0x Ax
