Count Vowels and Consonants in a String

Write a C program that counts the number of vowels and consonants in a given string.

Problem Statement:

• Given a string s consisting of uppercase and lowercase English alphabets, count and print:
  • The number of vowels in the string.
  • The number of consonants in the string.
• Ignore any non-alphabetic characters.

Input Format:

• s: A string containing uppercase and lowercase alphabets.

Output Format:

• Print the number of vowels and consonants in the string.

Example Inputs & Outputs:

Enter the string: Hello World
Vowels: 3
Consonants: 7
            

Enter the string: C Programming
Vowels: 3
Consonants: 9
            

Constraints:

• 1 ≤ length of s ≤ 1000

Hint:

To solve this problem, follow these steps:

1. Iterate Through the String:
   • Use a loop to go through each character of the string.
   • Check if the character is a letter using the isalpha() function.
2. Check for Vowels and Consonants:
   • Convert the character to lowercase using tolower() if necessary.
   • Check if the character is a vowel:

     if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u')
                                 

   • If the character is not a vowel but is an alphabet, it is a consonant.
3. Ignore Non-Alphabetic Characters:
   • Use the isalpha() function to check if the character is a letter.
4. Print the Count:
   • Print the final count of vowels and consonants.

Formula Breakdown:

• Vowel Check:

  if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u')
                      

• Consonant Check:

  if (isalpha(ch) && !isVowel(ch))
                      

Task: Implement the above logic and write a C program to count the number of vowels and consonants in a string.
