find the number of alphabet vowels and words in input using string

Sure, here is a Python solution for your problem:

def count_vowels_and_words(input_string):
    vowels = "aeiouAEIOU"
    vowel_count = 0
    word_count = 0

    for char in input_string:
        if char in vowels:
            vowel_count += 1

    words = input_string.split()
    word_count = len(words)

    return vowel_count, word_count

input_string = "Hello, how are you?"
vowel_count, word_count = count_vowels_and_words(input_string)

print("Number of vowels: ", vowel_count)
print("Number of words: ", word_count)

In this code:

1. We define a function count_vowels_and_words that takes an input string.
2. We define vowels as a string containing all the vowels in both lower and upper case.
3. We initialize vowel_count and word_count to 0.
4. We iterate over each character in the input string. If the character is in vowels, we increment vowel_count.
5. We split the input string into words using the split method, which splits a string into a list where each word is a list item. We then get the length of this list to find the number of words, and assign this to word_count.
6. The function returns vowel_count and word_count.
7. We call this function with an example string "Hello, how are you?" and print the number of vowels and words.
