Since a user is allowed to enter an alphabet in lowercase and uppercase, the program checks for both uppercase and lowercase vowels and consonants. To understand this program, you should be familiar with the following C Programming concepts: #include <stdio.h> int main() { char ch; bool isVowel = false; printf("Enter an alphabet: "); scanf("%c",&ch); if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I' ||ch=='o'||ch=='O'||ch=='u'||ch=='U') { isVowel = true; } if (isVowel == true) printf("%c is a Vowel", ch); else printf("%c is a Consonant", ch); return 0; }
