8. Define a function SOD to get an integer number as argument and return the sum of the digits of that number. For example, if the argument is 1537, the function should return 16 (which is sum of 1 + 5 + 3 + 7). Also write a minimal C++ program to use this function.

9. WAP to read a string and determine whether that is a (non case sensitive) palindrome or not.
Eg. Madam is a palindrome.
(note ‘M’ & ‘m’ are equal in this non case sensitive example)

10. Write a program in C++ to read a sentence and calculate the following:
(i) no. of lower case alphabets
(ii) no. of upper case alphabets
(iii)no. of special characters
(iv)no. of digits

11. WAP to read a string and encode as follow:
The sequence of the words would be same but the characters of each word will appear in reverse order.
Example:          Original String:        I LOVE INDIA
                        Encoded String:       I EVOL AIDNI

12. Write a program to read a name and then display the same but in sentence form as follow:
If the inputted name is       : MOHaNdas KaRAMChAnd GaNdhi
The output would be          : Mohandas Karamchand Gandhi

13. Define a function to read a name (string) as an argument and display the initials of that name with the full last name. e.g. for an argument ‘MOHANDAS KARAMCHAND GANDHI’, the output should be M K GANDHI.

14. Define a function HCF() to accept two arguments and return the HCF / GCD of those two numbers.
Using this function, write a program to read two positive integers and then check whether they are co-prime or not. Two numbers are said to be co-prime when they don’t have any common factor other then 1. (or HCF=1) e.g. 15 and 14 are co-prime.

15. Define a function isperfect( ) to check whether a number argument is a perfect number or not? Your function should return 1 if the number is perfect otherwise 0. Also write a minimal C++ program to use this function.
Note: A number is perfect if sum of all its factor is that number itself. Eg. 6 is a perfect no. as 6=1+2+3

16. Define a function to get a natural number as argument and return the same but in reverse order. For example, if the argument is 1537, the function should return 7351. Using this function, write a C++ program to check whether an inputted integer is palindrome or not.

17. Write a C++ program to display all prime factors of a number inputted by the user.
