Question

How many iterations will loops execute?

Answer 1

Answer:

(a)20

(b)20

(c)15

(d)20

(e)10

(f)5

Explanation:

(a) In this loop it start from "0" and iterated up to the value of i= "19" because there is 1 increment in each iteration i.e(i++) so total iterations will executed 20.

(b) In this loop it starts from "1" and iterated up to the value of i="20" because there is 1 increment in each iteration i.e(i++) so total iterations will executed 20.

(c) In this loop it start from "5" and iterated up to the value of i= "19" because their is 1 increment in each iteration i.e(i++) so total  iterations will executed 15.

(d) In this loop, it starts from "20" and iterated up to the value of i= "1" because there is 1 decrement in each iteration i.e(i--) so total iterations will execute 20.

(e) In this loop, it starts from "1" and iterated up to the value of i="19" because there is 2 increment in each iteration i.e(i=i+2) so total iterations will execute 10.

(f) In this loop, it starts from "1" and iterated up to the value of  i= "19" because there is  twice the increment of value of i=i*2 so total  iterations will executed 5
