Question
What do you mean by right shift and left shift operator? Write binary equivalentof the following numbers and perform the right and left shift on both of them. (2)(i) 23 (ii) 40
Solution
The right shift and left shift operators are used in programming languages to shift the bits of a number to the right or left, respectively.
To find the binary equivalent of a number, we can convert it from decimal to binary.
(i) For the number 23, the binary equivalent is 10111.
(ii) For the number 40, the binary equivalent is 101000.
Now, let's perform the right shift and left shift operations on both numbers.
Right shift (>>) moves the bits to the right by a specified number of positions. Each shift to the right divides the number by 2.
(i) Right shifting 23 by 1 position: 23 >> 1 = 11 in decimal, which is equivalent to 1011 in binary.
(ii) Right shifting 40 by 1 position: 40 >> 1 = 20 in decimal, which is equivalent to 10100 in binary.
Left shift (<<) moves the bits to the left by a specified number of positions. Each shift to the left multiplies the number by 2.
(i) Left shifting 23 by 1 position: 23 << 1 = 46 in decimal, which is equivalent to 101110 in binary.
(ii) Left shifting 40 by 1 position: 40 << 1 = 80 in decimal, which is equivalent to 1010000 in binary.
So, the results of the right and left shift operations are as follows: (i) Right shift of 23 by 1 position: 11 (ii) Right shift of 40 by 1 position: 20 (i) Left shift of 23 by 1 position: 46 (ii) Left shift of 40 by 1 position: 80
