Question 9

A class Rearrange has been defined to modify a word by bringing all the vowels in the word at the beginning followed by the consonants.
Example: ORIGINAL becomes OIIARGNL
Some of the members of the class are given below
Class name    Rearrange
Data member/instance variable:
wrd to store a word
newwrd to store the rearranged word
Member functions/methods:
Rearrange( ) default constructor
void readword( ) to accept the word in UPPER case
void freq_vow_con( ) finds the frequency of vowels and consonants in the word and displays them with an appropriate message
void arrange( ) rearranges the word by bringing the vowels at the beginning followed by consonants
void display( ) displays the original word along with the rearranged word
Specify the class Rearrange, giving the details of the constructor( ), void readword( ), void freq_vow_con( ), void arrange( ) and void display( ). Define the main( ) function to create an object and call the functions accordingly to enable the task
