Why does the word counter start at 1?
Short answer. Two words have only one space between them.
How do you test whether a character is a vowel?
Search for it in "AEIOU" with indexOf, which gives -1 if not found.
Inside the loop
| Count | Check | Start |
|---|---|---|
| Vowels | in "AEIOU" | c = 0 |
| Words | ch == ' ' | c = 1 |
| Letter A | ch == 'A' | c = 0 |
Remember
| Check each char with if |
| Start the counter right |
Vowels, words, letters. One loop counts them all. For vowels, search in A E I O U. For words, count spaces, starting at one. For one letter, compare each character. Check each character with if. Start the counter at the right value.
