Find
find( item, index )
Starts at a 0 index and returns index position of your input. Optional 2nd argument can tell you which index to start at so as to skip the first occurrence of something.
// userText is "Help me!"
userText.find('p') // Returns 3
userText.find('e') // Returns 1 (first occurrence of e only)
userText.find('z') // Returns string::npos
userText.find("me") // Returns 5
userText.find('e', 2) // Returns 6 (starts at index 2)
