Slip 9 - A) Write a C program to accept a character from the user and check whether the character is a vowel or consonant.

Solution:

#include <stdio.h>

int main()

{

    char c;

    int isLowercaseVowel, isUppercaseVowel;

    printf("Enter an alphabet: ");

    scanf("%c",&c);

        isLowercaseVowel = (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u');

        isUppercaseVowel = (c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U');

    if (isLowercaseVowel || isUppercaseVowel)

        printf("%c is a vowel.", c);

    else

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

    return 0;

}
