Now it's your turn to use string methods.

?: Get enthusiastic about ruby! How do I print out "I love ruby" in all caps?

( ) '"I love Ruby".swapcase' (X) '"I love Ruby".upcase' ( ) '"I love Ruby".uppercase'

?: Use a method to print out how long this sentence is: "This is a pretty long string. I wonder how long it is?"

(X) '"This is a pretty long string. I wonder how long it is?".length' ( ) '"This is a pretty long string. I wonder how long it is?".swapcase' ( ) '"This is a pretty long string. I wonder how long it is?".printlength'

?: It's backwards day! How would you print "backwards" backwards?

( ) '"backwards".length' ( ) '"backwards".backwards' (X) '"backwards".reverse'

?: Wouldn't it be great if there was a string method that always capitalized the first letter of a string? There is! "make it capitalize the first letter in this string!"

( ) '"make it capitalize the first letter in this string!".upcase' ( ) '"make it capitalize the first letter in this string!".swapcase' (X) '"make it capitalize the first letter in this string!".capitalize'

?: How much do we love "Ruby"? So much that we want to say it in all caps AND backwards. How would you do this?

( ) '"Ruby".captialize.reverse' ( ) '"Ruby".reverse.swapcase' (X) '"Ruby".upcase.reverse'
