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: RearrangeData 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 casevow 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.
