Question

a1 = ++ a – a++ + -- a if a = 5​

Answer 1

Required Answer:-

Given:

• a = 5
• a1 = ++a – a++ + --a

To Find:

• The value of a1. (Java)

Solution:

Given that,

>> a = 5

Now,

>> a1 = ++a – a++ + --a

>> a1 = 6 – a++ + --a  (a becomes 6, pre-increment)

>> a1 = 6 – 6 + --a   (a is 6, post-increment)

>> a1 = 6 – 6 + --a   (a becomes 7)

>> a1 = 6 - 6 + 6  (a becomes 6, pre-increment)

>> a1 = 0 + 6

>> a1 = 6

Therefore,

>> a1 = 6 and a = 6

Answer:

• a1 = a = 6
