Vowel program in c

Check Vowel Program

We can check if a character entered by the user is a vowel or a consonant by using an if-else statement or a switch case block.

Code for checking for vowels and consonants by using if-else

 
#include <stdio.h>
int  main()
{
char  ch;
printf("Enter a character:");
scanf("%c", & amp; ch);
if  (ch == 'a'  || ch == 'A'  || ch == 'e'  || ch == 'E'  || ch == 'i'  || ch == 'I'  || ch == 'o'  || ch == 'O'  || ch == 'u'  || ch == 'U') //checking if the character is a vowel
  printf("%c is a vowel.\n", ch);

else
  printf("%c is a consonant.\n", ch);

return  0;
}

The output for the above code is:

Enter a character: A

A is a vowel.

Code for checking for vowels and consonants by using switch case:

 
#include <stdio.h>
int  main()
{
char  ch;
printf("Enter a character: ");
scanf("%c", & amp; ch);
switch (ch)
{
  //checking if the character is a vowel in all the cases below

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 isn't a vowel.\n", ch);

}
return  0;
}

The output for the above code is:

Enter a character: A

A is a vowel.
