QUESTION 25

Given the array

How would you access the last element of the array?

cost[3]

A.

0 1 2

B.

0 1

C.

1

D.

1 2

Explanation / Answer

1.
D. 1,2

m=0
So first it compares 0<2 and since m is incremented it prints 1 i.e.m=1
then it compares 1<2 and since m is incremented it prints 2 i.e. m=2
and now 2<2 returns false so it exits the loop

2.
D. quantity=(int)value;

In A. you cannot store a double value in an int variable
In B. It is the same thing
In C. you cannot store a string in an int variable
In D. you are using type conversion and storing the double value in an integer

3.
D. val is less than 4

from the given code val will print 'Test A' if the val is greater than or equal to 4. and 'Test B' will never get printed because if val>9 then it is greater than 4 and first if statement will be executed. So Test C is printed if val is less than 4.

4.
B. 0 represents a false condition.

Any non-zero value even if it positive or negative represents a true condition.
