STEP 1
Assumptions1. The code is written in a C-like language, where operations are performed in a specific order according to operator precedence.
. The variables a and b are integers.
3. The operations are performed in the order they appear in the code.
4. The "+=" operator means "add and assign," so "a+=a" is equivalent to "a = a + a".
5. The "*=" operator means "multiply and assign," so "b*=4+5" is equivalent to "b = b * (4+5)".
6. The division operator "/" performs integer division, which discards the remainder and only keeps the quotient.
7. The multiplication and division operations have higher precedence than addition and subtraction, and are performed from left to right.
STEP 2
First, we initialize the variable a.
STEP 3
Next, we perform the operation "a+=a", which is equivalent to "a = a + a".
STEP 4
Now, we calculate the value of b. We need to pay attention to the order of operations. First, we perform the multiplication and division operations.
STEP 5
Perform the multiplication and division operations.
STEP 6
Now, perform the addition operations to calculate the value of b.
STEP 7
Finally, we perform the operation "b*=4+5", which is equivalent to "b = b * (4+5)".
STEP 8
Calculate the new value of b.
So, the values of a and b after executing the code are2 and135, respectively.
