Question

how to solve this question?

Write a statement that assigns to x the value the bits 2, 3, and 4 of the integer y; x = _____________;

For example if y = 0x35 then the value of x after the execution of the statement will be 5;

Answer 1

Solution for the problem is provided below, please comment if any doubts:

Here the x value should be assigned with the values of the 2, 3, and 4^th bits of the integer y.

To perform this task, first we need to extract the 2, 3, and 4^th bits from y, this can be performed by using an AND operation with z, where z= ox1C = 00011100 (in binary)

Next, right shift the result by two bits right.

The statement is: SHIFT_RIGHT ((x AND ox1C), 2)
