how we find vowel words

Programme:

#include<iostream>

using namespace std;

int main()

{

char ch;

cout<<"Enter an alphabet=";

cin>>ch;

{

if(ch=='A'||ch=='a'||ch=='E'||ch=='e'||ch=='I'||ch=='i'||ch=='O'||ch=='o'||ch=='U'||ch=='u')

cout<<ch<<":is a vowel";

else

cout<<ch<<":is not a vowel";

}

}
