Question

evaluate the following expressions if the value of the variable are a=2 ,b=3 and c=9
1) a-(b++)*(--c)
2) a*(++b)/c​

Answer 1

Answer:

ANSWER

(a) a - (b++) * (--c);

22

WORKING

a - (b++) * (--c)

⇒ 2 - 3 * 8 [∵ b++ uses current value of b in expression and then increments it, --c decrements c to 8 and then uses this 8 in the expression]

⇒ 2 - 24

⇒ -22

(b) a * (++b) % c;

8

WORKING

a * (++b) % c

⇒ 2 * 4 % 9 [∵ ++b increments b to 4 then uses it in the expression]

⇒ 8 % 9

⇒ 8
