C Program To Check If The Input Is Vowel or Consonant

C Program To Check If The Input Is Vowel or Consonant: In this program, we will learn to write a code to check if the input is vowel or consonant.

In this program we use:

• Switch Statement
• Default statement
• Break statement
• Programming Operators

Working:

• The five letters A, E, I, O, U both including uppercase and lowercase are called vowels. All other alphabets except vowels are called consonants.
• This program will always assume the input to be an Alphabet.
• If we don't use break; statement all the cases following the valid case are executed and evaluated.
• default; statement is executed if all the above cases are false. It is similar to the else statement of if-else code.

Source Code:

#include<stdio.h>

int main()

{

    printf("\t\t\tScribbled Writer\n\n");

    char ch;

    printf("Enter a Character :  ");

    scanf("%c", &ch);

    switch(ch)

    {

        case 'a':

        case 'A':

        case 'e':

        case 'E':

        case 'i':

        case 'I':

        case 'o':

        case 'O':

        case 'u':

        case 'U':

            printf("%c is a vowel.\n", ch);

            break;

         default:

            printf("%c is a consonant.\n", ch);

    }

    printf("\n\tHappy Coding!\n");

    return 0;

}

Output:

Ex-1

       Scribbled Writer

a is a vowel.

       Happy Coding!

Ex-2

     Scribbled Writer

G is a consonant.

        Happy Coding!
