C program to check Vowel or consonant using switch case

In this article, we will discuss the concept of the C program to Check Vowel or consonant using switch case statements

In this post, we are going to learn how to check the vowels and consonants using switch statements in C programming language

C program to check Vowel or consonant using switch case with the break

The program allows to enter an Alphabet and it checks and displays whether the given alphabet is vowel or consonant with the break statements

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char ch;
    printf("Enter any Alphabet\n"); //input alphabet from user
    scanf("%c",&ch);//store the Entered Alphabet in ch

    switch(ch){
    //check lower case vowel letters
    case 'a':
    printf("%c is a vowel",ch);
    break;

    case 'e':
    printf("%c is a vowel",ch);
    break;

    case 'i':
    printf("%c is a vowel",ch);
    break;

    case 'o':
    printf("%c is a vowel",ch);
    break;

    case 'u':
    printf("%c is a vowel",ch);
    break;

    //check upper case vowel letters
    case 'A':
    printf("%c is a vowel",ch);
    break;

    case 'E':
    printf("%c is a vowel",ch);
    break;

    case 'I':
    printf("%c is a vowel",ch);
    break;

    case 'O':
    printf("%c is a vowel",ch);
    break;

    case 'U':
    printf("%c is a vowel",ch);
    break;

    default:
    printf("%c is a consonant",ch);
    break;
    }
    getch();

    return 0;
    }

When the above code is executed, it produces the following result

case 1

Enter any Alphabet
a
a is a vowel

case 2

Enter any Alphabet
E
E is a vowel

case 3

Enter any Alphabet
M
M is a consonant

case 4

Enter any Alphabet
y
y is a consonant

Approach

Define a character variable ch
The program is asked the user to enter an Alphabets to check whether vowel or consonant
Entered character is stored in the ch variable
Define cases for the character ch with vowel character both capital and small
Next, the program checks every case using the given character.
Finally, it displays whether the given character is vowel or consonant

C program to check Vowel or consonant using switch case without the break

The program allows to enter an Alphabet and it checks and displays whether the given alphabet vowel or consonant without the break statements

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char ch;
    printf("Enter any Alpabet\n"); //input alphabet from user
    scanf("%c",&ch);//store the Entered Alphabet in ch

    switch(ch){
    //check lower case vowel letters
    case 'a':
    case 'e':
    case 'i':
    case 'o':
    case 'u':

    //check upper case vowel letters
    case 'A':
    case 'E':
    case 'I':
    case 'O':
    case 'U':

        printf("%c is a vowel",ch);
        break;

    default:
        printf("%c is a consonant",ch);
        break;

}
    getch();

    return 0;
    }

When the above code is executed, it produces the following result

case 1

Enter any Alphabet
e
e is a vowel

case 2

Enter any Alphabet
U
U is a vowel

case 3

Enter any Alphabet
G
G is a consonant

case 4

Enter any Alphabet
r
r is a consonant

Approach

Define a character variable ch to check the entered character
The program is asked the user to enter an Alphabets to check whether vowel or consonant
Entered character is stored in the ch variable
Define cases for the character ch with vowel character both capital and small
Next, the program checks every case using the given character.
Finally, it displays whether the given character is vowel or consonant
