#include <stdio.h>
int main()
{
    char ch;
    bool isVowel = false;

    scanf("%c",&ch);
    if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I'
    		||ch=='o'||ch=='O'||ch=='u'||ch=='U')
    {
    	isVowel = true;
    }
    if (isVowel == true)
        printf("%c is a Vowel", ch);
    else
        printf("%c is a Consonant", ch);
