Question

Input a word in uppercase and check for the position of the first occurring vowel and perform the
following operation.
(i)Words that begin with a vowel are concatenated with “Y”.
For example:- EUROPE becomes EUROPEY.
(ii) Words that contains a vowel in-between should have the first part from the position of the vowel till end , followed by the part of the string from beginning till position of the vowel and is concatenated by “C”.
For example – PROJECT becomes OJECTPRC.
(iii) Words which do not contain a vowel are concatenated with “N”.
For example – SKY becomes SKYN.
Design a class Rearrange using the description of the data members and member functions given below:
Classname:Rearrange
Data Members/instance variables:
Txt: to store a word
Cxt: to store the rearranged word
len: to store the length of the word
Member functions:
Rearrange():constructor to initialize the instance variables
void readword():to accept the word input in UPPERCASE
void convert():converts the word into its changed form and stores it in string Cxt
void display():displays the original and the changed word
Specify the class Rearrange giving the details of the constructor( ), void readword( ),void convert() and void display() . Define a main() function to create an object and call the function accordingly to enable the task.

Input:
ENTER THE SIZE OF ARRAY:10
ENTER THE ELEMENT IN THE ARRAY:
1 2 3 4 5 6 7 8 9 10

ARRAY AFTER DELETING EVEN POSITION ELEMENTS:
2 4 6 8 10
