Question

write a program to input a single character and check it is vowel or not.​

Answer 1

Answer:

include <stdio.h>

int main() {

char c;

int lowercase_vowel, uppercase_vowel;

printf("Enter an alphabet: ");

scanf("%c", &c);

// evaluates to 1 if variable c is a lowercase vowel

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

// evaluates to 1 if variable c is a uppercase vowel

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

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

if (lowercase_vowel || uppercase_vowel)

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

else

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

return 0;

}

Output

Enter an alphabet: G

G is a consonant.
