Explanation:<\/h2>\n\n\n\n
Purpose<\/strong>: The program checks if a given character is a vowel or a consonant.<\/p>\n\n\n\n
Steps<\/strong>:<\/p>\n\n\n\n
    \n
  1. Input<\/strong>: It prompts the user to enter a character.<\/li>\n\n\n\n
  2. Check Validity<\/strong>: It verifies if the character is a letter (A-Z or a-z).<\/li>\n\n\n\n
  3. Determine Type<\/strong>:\n
      \n
    • If it’s a vowel (A, E, I, O, U), it prints that it’s a vowel.<\/li>\n\n\n\n
    • If it’s a letter but not a vowel, it prints that it’s a consonant.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Invalid Input<\/strong>: If the input isn’t a letter, it displays an error message.<\/li>\n<\/ol>\n\n\n\n
      Output:<\/h2>\n\n\n\n
      1.Enter a character: z\nz is a consonant.\n\n2.Enter a character: e\ne is a vowel.<\/code><\/pre>\n\n\n\n
