a+= 17

not sure

Answer 2

Answer:

Step 1:a=6 (given)

Step 2:b= (++a)+(a++)+(a++) ––––(1)

Explanation:

1. ++a=7 (pre-increment) so (6+1=7) will be assigned to a.
2. a++=7 (post increment) it will remain same here, then value of a will be 8 in next step
3. a++=8 (post increment) so now value of a will be 9 for further.

Step 3: Now put the values of these three sub- steps in eq. (1) to get value of b.

b=7+7+8=22.

step 4: in sub step (3) we can say value of a=9.

so,a=9, b=22.
