Answer 1

The value of z will be 420.

Answer 2

Answer:

• The value of z is 420.

Explanation:

It's given that,

y = 14

z = ++y *(y-- + --y)

Let's calculate the value of z.

>> z = ++y * (y-- + --y)

>> z = 15 *(y-- + --y) [Pre-increment, value of y will be incremented first]

>> z = 15 * (15 + --y) [Post-increment, value of y will be incremented after substituting it in the expression]

>> z = 15 * (15 + --y) [y becomes 14 now]

>> z 15 * (15 + 13) [Pre-decrement, value of y will be decremented first]

>> z = 15 × 28

>> z = 15 × 2 × 14

>> z = 30 × 14

>> z = 420

Hence, the value of z is 420.
