Answer to Question #277568 in C++ for Ana

Question

Write a Menu Driven C++ program that creates a character array/string by taking input from user and

perform following tasks by displaying menu to user, the menu operations are implemented using

functions:

a) Length of string.

b) Character, consonants and vowels count in a string

c) Palindrome check

d) Character search within the string. If found display its starting position.

e) covert to either case
