Q2. If Num is an integer variable then Num++ means,

Add 1 two times with Num

Add 1 with Num

Add 2 with Num Subtract 2 from Num

Q3. combinations of

values that can be stored in n bits is 2n. For example: 1 bit can hold 2 = 2^1 = 2 possible values (0 or 1) 2 bits can hold 2 × 2 = 2^2 = 4 possible values so 8 bits(one byte) = 2^8 = 256
