Design a class Sort which enables a word to be arranged in alphabetical order. The details of the members of the class are given below :
Class name: Sort
Data members/instance variables:
str: stores a word.
len: to store the length of the word.
Member functions:
Sort( ): default constructor.
void readWord( ): to accept the word.
void arrange( ): to arrange the letters of the word in alphabetical order using any standard sorting technique.
void display( ): displays the original word along with the sorted word.
Specify the class Sort giving details of the constructor, void readword( ), void arrange( ), and void display(). Define the main( ) function to create an object and call the functions accordingly to enable the task.
