45 : C Program to Check Entered char is a Vowel or Consonant

Check out the complete list of c-programs : C Program List    



This program reads in a char value from the console and checks if its a Vowel or a Consonant. If the char is 'a','e','i','o' or 'u' than its a vowel else its a consonent.

We also need to check upper cases and lower cases (ie A E I O U).

We can use if else or switch-case statement to achieve this.

Variables :

ch : Datatype char : Holds value of number inputted by the user. %c is the Format specifier for char's
