Question

What is the range of values that a short can represent?

a. 0 to 256
b. -127 to 128
c. Math.pow(-2.0,15.0) to (Math.pow(2.0,15.0) -1)
d. 0 to Math.pow(2.0,16.0)

Answer 1

Answer:

c. Math.pow(-2.0,15.0) to (Math.pow(2.0,15.0) -1).

Explanation:

short represents a 16-bit signed integer. short is used to save memory because it occupies less space than integers where integers occupy 4 bytes short occupies 2 bytes.

Since it is signed so first bit is used to represent the sign if 0 then positive and 1 then the integer is negative.We are left with 15 bits.

So the range is -2¹⁵ to 2¹⁵-1.

Hence the answer is option c.
