Rewrite the following statements using augmented assignment operators: a) quantity = quantity + 1 b) days_left = days_left ? 5 c) price = price * 10 d) price = price / 2

Short Answer

Expert verified

5 (typo) Corrected Original Statement: days_left = days_left - 5 Rewritten Statement: days_left -= 5 3. Rewrite the given multiplication statement using an augmented assignment operator. Original Statement: price = price * 10 Rewritten Statement: price *= 10 4. Rewrite the given division statement using an augmented assignment operator. Original Statement: price = price / 2 Rewritten Statement: price /= 2

Step by step solution

a) Rewrite the addition statement using augmented assignment operator

The addition statement, 'quantity = quantity + 1', can be rewritten using the '+=' augmented assignment operator. This simplifies the statement and performs the same operation. Here's the rewritten statement: ``` quantity += 1 ```

b) Rewrite the subtraction statement using augmented assignment operator

There is a typo in the original statement ('days_left = days_left ? 5'). It should be 'days_left = days_left - 5'. To rewrite the subtraction statement using the augmented assignment operator, we should use the '-=' operator. Here's the corrected and rewritten statement: ``` days_left -= 5 ```

c) Rewrite the multiplication statement using augmented assignment operator

The multiplication statement 'price = price * 10' can be rewritten using the '*=' augmented assignment operator. This simplifies the statement and performs the same operation. Here's the rewritten statement: ``` price *= 10 ```

d) Rewrite the division statement using augmented assignment operator

The division statement 'price = price / 2' can be rewritten using the '/=' augmented assignment operator. This simplifies the statement and performs the same operation. Here's the rewritten statement: ``` price /= 2 ```
