Question

If a = 5, b = 9, calculate the value of:

a += a++ - ++b + a [4]​

Answer 1

Answer:

6

Explanation :-

a += a++ - ++b + a

⇒ a = a + (a++ - ++b + a)

⇒ a = 5 + (5 - 10 + 6) [∵ a++ will first use current value of a then increment it to 6. ++b will increment b to 10 and use the incremented value. As a++ incremented a to 6 so the value of last a in the expression is 6]

⇒ a = 5 + 1

⇒ a = 6

Answer 2

QUESTION:-

If a = 5 , b=9 find:-

a+=a++ - ++b + a

ANSWER:-

a=6

STEP-BY-STEP EXPLANATION:-

a+= a++ - ++b +a

=a + a++ - ++b +a

=5+5-10+6

(The a++ describes first assign then increment so the value of a(5) will be assigned then the value of a will increase to 6 and b++ describes assign after increment so the value of b(9) will be increased and then assigned .)

=10-10+6

(By following the JAVA BEDMAS RULE OF HIERARCHY)

=0+6

=6
