```Instruction(s) inside the while block{} are executed repeatedly till  expression  (num>=10)  is true.

Divide the number num by 10 untill it becomes lesser than 10. once it is less than 10 check whether the num is odd or even.

statement num = num/10 divides the num by 10 repeatedly untill it num is less than 10.```
