Let x = 131 in base 10. If x is represented as an 8-bit unsigned binary integer, and you apply the operation x << 4, what will the result be in base 10?

Question

Let  x = 131 in base 10. If  x  is represented as an 8-bit unsigned binary integer, and you apply the operation  x << 4, what will the result be in base 10?

Answer 1

131 base 10 in binary will be: 10000011, so as an unsigned 8-bit it will be:10000011

x<<4 shifts x over 4 times to the left

The first shift will give: 00000110 (cutting off the first 1 because we only have 8-bits)

The second will give: 00001100

The third will give: 00011000

The fourth will give: 00110000

Converting back to base 10 gives us 48.

Answer 2

131 in base 10 = 10000011 (8 bits unsigned)

10000011 << 4 = 00001100

00001100 = 12 in base 10

let me know if any question
