Question

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.
