Question

what will be the new value of k from : k=(k%3==0)? (k*3) :(k+3) if k=15 (ii) k =0
answer me fast​

Answer 1

Answer:

k = 15

45

k = 0

0

Explanation:

The expression, (k%3==0)? (k*3) :(k+3), checks if k is divisible by 3 or not, if yes then evaluate to (k * 3) else evaluate to (k + 3)

15 is divisible by 3, so k = 15 * 3

0 is also divisible by 3, because when you divide 0 by 3 you get 0 remainder which is the definition of divisibility, so k = 0

Answer 2

Answer:

The given expression is a ternary operator

$\tt \: \orange{k=(k \%3==0)?(k*3):(k+3);}$

Solution:-

• when k=15

$\tt \: \orange{k=(k \%3==0)?(k*3):(k+3);} \\ : \implies \: (15 \%3==0)?(15*3):(15+3) \\ : \implies \: (true)?(45):(18)$

Since the condition is true, k will store 45 as it's value.

• when k=0

$\tt \: \orange{k=(k \%3==0)?(k*3):(k+3);} \\ : \implies \: (0 \%3==0)?(0*3):(0+3) \\ : \implies \: (true)?(45):(18)$

Here, again the condition is true, k will store 0 as it's new value

Final Answer:-

• When k=15,

k=45

• When k=0,

k=0
