logics in mind:-
>first we enter a number(for 'n').
->If we have number 123 then its odd positioned digits are 1 and 3(from both side). It means, first we have to get 3 then 2 and then 1 to check all digits.
->For this,
->we have to divide by 10 to get last digit.
->we also use 'count' with initial value '0' to to know position of digits.
->we divide that count by 2 to get remainder.If count is not equal to 2 then we understand that the digit is in odd position and if not then that is not.
->Then we display that.
-> to get second digit, we get first 12 and for this , we use 123/10.It is done to get integer part only.
->We repeat this until the value reaches 0. We use loop for this as shown above in the code.
