C Program to Check Vowel or Consonant

C program to check vowel or consonant; Through this tutorial, we will learn how to check whether an alphabet is vowel or consonant using function, ascii value and if else in c program.

Programs to Check Vowel or Consonant in C

• C program to check whether an alphabet is vowel or consonant using if else
• C Program to find Vowel or Consonant using Functions
• C Program to Check Vowel or Consonant using ASCII Values

C program to check whether an alphabet is vowel or consonant using if else

// C Program to Check Vowel or Consonant
#include <stdio.h>

int main()
{
    char ch;

    printf("Please Enter an alphabet: ");
    scanf(" %c", &ch);

    if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ||
		ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U')  {
		printf("\n %c is a VOWEL.", ch);
	}
    else {
    	printf("\n %c is a CONSONANT.", ch);
	}
    return 0;
}

The output of the above c program; as follows:

Please Enter an alphabet: i
i is a VOWEL.

C Program to find Vowel or Consonant using Functions

// C Program to Check Whether an Alphabet is Vowel or Consonant
#include <stdio.h>
int check_vowel(char a);
int main()
{
    char ch;
    printf("Please Enter an alphabet: ");
    scanf(" %c", &ch);

    if(check_vowel(ch))  {
		printf("\n %c is a VOWEL.", ch);
	}
    else {
    	printf("\n %c is a CONSONANT.", ch);
	}
    return 0;
}

int check_vowel(char c)
{
    if (c >= 'A' && c <= 'Z')
       c = c + 32;

    if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
       return 1;

    return 0;
}

The output of the above c program; as follows:

Please Enter an alphabet: g
g is a CONSONANT.

C Program to Check Vowel or Consonant using ASCII Values

// C Program to Check Whether it is Vowel or Consonant
#include <stdio.h>

int main()
{
    char ch;

    printf("Please Enter an alphabet: ");
    scanf(" %c", &ch);

    if(ch == 97 || ch == 101 || ch == 105 || ch == 111 || ch == 117 ||
	ch == 65 || ch == 69 || ch == 73 || ch == 79 || ch == 85)
    {
    	printf("%c is a VOWEL.\n", ch);
    }
    else if((ch >= 97 && ch <= 122) || (ch >= 65 && ch <= 90))
    {
        printf("%c is a CONSONANT.\n", ch);
    }

    return 0;
}

The output of the above c program; as follows:

Please Enter an alphabet: a
a is a VOWEL.
