#include
int main()

 char ch;
 printf("Enter a Charecter :");
 scanf("%c",&ch);
 if((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z'))
 {
 if (ch == 'a' || ch == 'A' || ch == 'e' || ch == 'E' || ch == 'i' || ch == 'I' || ch =='o' || ch=='O' || ch ==
'u' || ch == 'U')
 printf("'%c' is a vowel.\n", ch);
 else
 printf("'%c' is a consonant.\n", ch);
 }
 else if(ch >= '0' && ch <= '9')
 {
 printf("'%c' is digit.", ch);
 }
 else
 {
 printf("'%c' is special character.", ch);
