Check Whether a Character is a Vowel or Consonant in C Programming

How to Check Vowel or Consonant in C Programming

The English characters a, e, i, o, and u are lowercase and uppercase characters are known as vowels. Alphabets without vowels are known as consonants.

Given a c program in below using if-else to check whether an alphabet is a vowel or consonant. In this program, take input a character from the user and check whether it is vowel or consonant.

#include<stdio.h>
int main()
{
char L;

    // Input character from user
printf("nEnter a Lettern");
scanf("%c",&L);

 if ((L >= 'a' && L <= 'z') || (L >= 'A' &&L <= 'Z')) {

    // Condition for lowercase vowel
if(L=='a'||L=='e'||L=='i'||L=='o'||L=='u')
printf("n%c is a Vowel",L);

    // Condition for uppercase vowel
else if(L=='A'||L=='E'||L=='I'||L=='O'||L=='U')
printf("n%c is a Vowel",L);
else
printf("n%c is a Consonant",L);}
else
    printf("%c is a Non-alphabetic character.n", L);
getch();
}
