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 members/instance variables:
wrd: to store a word
newwrd: to store the rearranged word
Member functions/methods:
Rearrange(): default constructor
void readword(): to accept the word in uppercase
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 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.
