C program to check vowel or consonant using switch case

Example
Input

Input alphabet: c

Output

'c' is consonant

/**
 * C program to check vowel or consonant using switch case
 */

#include <stdio.h>

int main()
{
    char ch;

    /* Input an alphabet from user */
    printf("Enter any alphabet: ");
    scanf("%c", &ch);

    /* Switch value of ch */
    switch(ch)
    {
        case 'a': 
            printf("Vowel");
            break;
        case 'e': 
            printf("Vowel");
            break;
        case 'i': 
            printf("Vowel");
            break;
        case 'o': 
            printf("Vowel");
            break;
        case 'u': 
            printf("Vowel");
            break;
        case 'A': 
            printf("Vowel");
            break;
        case 'E': 
            printf("Vowel");
            break;
        case 'I': 
            printf("Vowel");
            break;
        case 'O': 
            printf("Vowel");
            break;
        case 'U': 
            printf("Vowel");
            break;
        default: 
            printf("Consonant");
    }

    return 0;
}

/*
Output :

Enter any alphabet: E
VOWEL
*/

Another approach:

/**
 * C program to check vowel or consonant using switch case
 */

#include <stdio.h>

int main()
{
    char ch;

    /* Input alphabet from user */
    printf("Enter any character: ");
    scanf("%c", &ch);

    /* Switch ch value */
    switch(ch)
    {
        case 'a': 
        case 'e': 
        case 'i':
        case 'o':
        case 'u':
        case 'A':
        case 'E':
        case 'I':
        case 'O':
        case 'U': 
            printf("Vowel");
            break;

        default: printf("Consonant");
    }

    return 0;
}

/*
Output :

Enter any alphabet: E
VOWEL
*/
