Run your Ruby file by typing ruby and then the name of the file you want to run in the Terminal.

If we want to run string_multiplication.rb, we can write the command:

ruby string_multiplication.rb

To re-run this command, you can use the UP and DOWN arrow keys to look at the history of commands you've run in a Terminal.

Should output:

"HoHoHo"

using String multiplication.

(Don't just print the String literal "HoHoHo")

Should output:

"HELLO friends AnD FaMiLy"

using a combination of the upcase, downcase, and swapcase methods.

Shoud output:

"Hello!"

using the given starting variable.

Should output:

"put spaces in between these words"

using the given starting variable.

Should output exactly

"no external whitespace"

using the given starting variable.

Write a program that gets a name (e.g. "alice") from the user, capitalizes it, and then says "Hello, Alice!"

Should work similarly to the following:

"What's your name?"
jelani
"Hello, Jelani!"
