Answer 1

Answer:

#include <stdio.h>

#include <ctype.h>

int main()

{

char c;

int isLowercaseVowel, isUppercaseVowel;

do {

printf("Enter an alphabet: ");

scanf(" %c", &c);

}

// isalpha() returns 0 if the passed character is not an alphabet

while (!isalpha(c));

// evaluates to 1 (true) if c is a lowercase vowel

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

// evaluates to 1 (true) if c is an uppercase vowel

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

// evaluates to 1 (true) if either isLowercaseVowel or isUppercaseVowel is true

if (isLowercaseVowel || isUppercaseVowel)

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

else

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

return 0;

}
