Write a C++ program to determine whether an entered character is lower case or upper case.

If letter is lower case, determine and print its position in the alphabet.

For example if letter 'c' is entered, your program should print 3.

Similarly if the entered letter is upper case letter, determine and print its position in the alphabet.

For example, if 'H' is entered, your program should print 7.

(Hint: If entered character is lowercase, its position can be determined by subtracting 'a' from the letter and adding 1. Similarly if entered character is upper case, its position can be determined by subtracting 'A' from the letter and adding 1.
