Question

Q99. What will be the final value of a and c in the following statement
A=2
C=1
C=(C) ? A= 0:2;
(A) A=0,C=0;
(B) A=2,C=2
(C) A=1,C=2
(D) A=2,C=0​

Answer 1

Answer:

For initialization a = 2, c = 1 the value of a and c after this code will be c = (c) ? a = 0 : 2;. A. a = 0, c = 0;; B. a = 2, c = 2;; C. a = 2, c = 2;; D. a = 1, c = 2;.

Answer 2

Answer:

The correct answer is (A) A = 0; C = 0

Explanation:

ternary operator: ?: is known as ternary operator.

Format of ternary operator:

condition ? statement1 : statement2

If condition is true, statement1 is executed otherwise statement2 is executed

Initiallly, a = 2, c = 1

c = (c) ? a=0 : 2

Now, condition is checked, The value of c is 1, for any non zero value of c condition will evaluate to true else false

c is non zero, so condition is true, a=0 will be executed

Now we know that the assignment statement returns the assigned value therefore a=0 will return 0

c will store value returned by a=0 i.e 0

a = 0 and c = 0

Therefore, value of 'a' and 'c:' (A) a = 0 and c = 0
