Write a C Program To determine whether an entered character is vowel or not.

Program:-

#include <stdio.h>
void main()
{
    char a;
    int isLowercaseVowel, isUppercaseVowel;
    printf("Enter an alphabet: ");
    scanf("%c",&a);
if(a == 'a'|| a == 'e' || a == 'i' || a == 'o' || a == 'u' || a == 'A' || a == 'E' || a == 'I' || a == 'O' || a == 'U' )
{
   printf(" vowel.",&a); 
}
 else
 {
        printf("not vowel",&a); 
 }

}

Output:-
