A vowel is a speech sound made with your mouth fairly open, the nucleus of a spoken syllable. A consonant is a sound made with your mouth fairly closed. There are about 20 vowels and 24 consonants. The below program checks whether the given letter is vowel-like a,e, i,o,u, or consonant like the rest of the letters. Vowels and consonants combine to form words. The letter ‘y’ is unique in that it can function as a consonant and a vowel at the same time. It will help you spell if you understand how vowels and consonants work together to form words and sounds.
STEP 1: Read the letter
STEP 2: Using a switch() condition check whether the letter is equal to a, e, i, o, u or A, E, I, O, U
STEP 3: If the condition matches then display the message 'it is vowel' and exit from the switch function using break statement
STEP 4: If the condition fails then, display the message 'it is consonant' and exit from the switch condition using break statement
