Question

If m = 8; find the value of m+ = m++ * ++m%2​

Answer 1

Answer.

• The final value of m is 8.

Steps.

Given –

> m = 8

Expression to be evaluated –

> m+=m++ * ++m%2

> m += 8 * ++m%2 (Value of m is not changed, post-increment)

> m += 8 * ++m%2 (m becomes 9)

> m += 8 * 10%2 (m becomes 10, pre-increment)

> m += 80%2

> m += 0 (As 80 divided by 2 leaves remainder 0)

> m = 8 + 0

> m = 8

★ So, the final value of m is 8.

There are two types of increment/decrement operations.

1. Post increment/decrement.
2. Pre increment/decrement.

Post Increment/Decrement – Here, operation takes place first and then the value is incremented/decremented.

Example –

> int a = 2;

> int b = a++;

> b = 2

Now, a = 3.

Here, initialisation takes place first and then value is incremented.

Pre Increment/Decrement – Here, value is first increment/decrement and then the operation is carried out.

Example –

> int a = 2;

> int b = ++a;

> b = 3

Also, a = 3

Here, increment takes first and then value is initialised.
