Using ternary operator check a character is Vowel or Consonant.

#include <stdio.h>

int main() {
    char ch;
    printf("Enter a Character:  \n");
    scanf("%c", &ch);

    ((ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u') || (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U')) ? printf("Vowel\n") : printf("Consonant\n");

    return 0;
}
