c program to check whether input alphabet is a vowel or not

C programming code

#include<stdio.h>
 
main()
{
      char ch;
 
      printf("Enter a character\n");
      scanf("%c",&ch);
 
      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 not a vowel.\n", ch);
 
      return 0;
}
Output:
check charater case output

Check vowel using switch statement

#include<stdio.h>
 
main()
{
   char ch;
 
   printf("Enter a character\n");
   scanf("%c",&ch);
 
   switch(ch)
   {
      case 'a':
      case 'A':
      case 'e':
      case 'E':
      case 'i':
      case 'I':
      case 'o':
      case 'O':
      case 'u':
      case 'U':
            printf("%c is a vowel.\n", ch);
            break;
      default:
            printf("%c is not a vowel.\n", ch);
   }                     
 
   return 0;
}
