Converting a string of words into correct cases

Let's say I have a string s:

Code:

---

string s = "How are YOU doING toDay?"

---

I want to convert this string so that only the first letter of each word is capitalized (so I want it to be: "How Are You Doing Today?"). I was thinking that it would be easier to first convert each letter to lowercase (using a string iterator and the tolower() function), and then capitalize the first letter of each word. But this is turning out to be more difficult than I thought. If it was just two words then I was thinking I can use substr() and find_first_of() to separate the words and capitalize each part, but the thing is I'm not guaranteed the number of words in the string. Any ideas are appreciated!

capitalize the first letter in the string
loop through the string to find spaces
capitalize the letter after each space

...and convert everything else to lowercase.
