Question

A class Sort Alpha has been defined to sort the words in the sentence in alphabetical order.

Example: Input: THE SKY IS BLUE
Output: BLUE IS SKY THE

Some of the members of the class are given below:

Class name	Short Alpha
Data members/instance variables:
sent	to store a sentence
n	integer to store the number of words in a sentence
Methods/Member functions:
ShortAlpha( )	default constructor to initialise data members with legal initial values
void acceptsent( )	to accept a sentence in UPPERCASE
void short(SortAlpha P)	sorts the words of the sentence of object P in alphabetical order and stores the sorted sentence in the current object
void display( )	display the original sentence along with the sorted sentence by invoking the method sort( )

Specify the class Sort Alpha giving details of the constructor (), void acceptsent(), void sort (Sort Alpha) and void display(). Define a main()function to create an object and call the functions accordingly to enable the task.
