Question

postfix, prefix
a=10 b=15
(++a)+(a++)+(++a)+(b++)+(++b)​

Answer 1

Answer:

Given :

• a = 10

• b = 15

Solution :

Postfix and Prefix :

(++a) + (a++) + (++a) + (b++) + (++b)

• ++a ( Prefix Increment )

++a = 1 + a

⟶ 1 + 10

⟶ 11

++a = 11

• a++ ( Postfix Increment )

⟶ a + 1

⟶ 10 + 1

⟶ 11

a++ = 11

• ++a ( Prefix Increment )

⟶ 1 + a

⟶ 1 + 10

⟶ 11

++a = 11

• b++ ( Postfix Increment )

⟶ b + 1

⟶ 15 + 1

⟶ 16

b++ = 16

• ++b ( Prefix Increment )

⟶ 1 + b

⟶ 1 + 15

⟶ 16

++b = 16

⟶ 11 + 11 + 11 + 16 + 16

⟶ 33 + 32

⟶ 65

______________

• Increment ( adding 1 to ) and decrementing ( substracting 1 from ) a variable are so common that they have their own operators in C.

• Prefix Increment - ++x - Increment x, then evaluate x

• Postfix Increment - x++ - Decrement x, then Increment x
