11 What is the range of rand15 a 0 15 b 0 15 c 0 15 d 0 15

11. What is the range of rand()%15 ?

a) (0, 15)

b) [0, 15)

c) (0, 15]

d) [0, 15]

e) None of the abover

Solution

rand() will give a random number but when 15 is used with modulus operator than the random number will be divided by the number 15 and the remainder will be returned hence when a number divided by 15 what values of remainder are possible [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14]

which is [0,15)

hence the option b is the answer.
