#include <iostream>
#include <string>
#include <cctype>
using namespace std;


class Vowel{
private:
    string inputWords;
public:
    Vowel(){}
    //the constructor member function to assign the values
    Vowel(string inputWords){
        this->inputWords=inputWords;
    }
    //destructor member function to destroy the data objects.
    ~Vowel(){}
    int vowelCount(){
        int vowels=0;
        for(int i = 0; i < this->inputWords.length(); ++i){
            char letter=tolower(this->inputWords[i]);
            if(letter=='a' || letter=='e' || letter=='i' || letter=='o' || letter=='u')
            {
                ++vowels;
            }
        }
        return vowels;
    }
};


int main (){
    string inputWords;
    cout<<"Enter your words: ";
    getline(cin,inputWords);
    Vowel vowel(inputWords);
    cout<<"\nThe number of vowels present in the given string: "<<vowel.vowelCount()<<"\n\n";


    system("pause");
    return 0;
