(Program) a. Write, compile, and run a C++ program that accepts a character as input data and determines whether the character is a lowercase letter. A lowercase letter is any character that’s greater than or equal to “a” and less than or equal to “z.” If the entered character is a lowercase letter, display the message “The character just entered is a lowercase letter.” If the entered letter isn’t lowercase, display the message “The character just entered is not a lowercase letter.”

b. Modify the program written for Exercise 14a to also determine whether the entered character is an uppercase letter. An uppercase letter is any character greater than or equal to “A” and less than or equal to “Z.”
