Challenge 1

Write a program that asks a person for their name and then says "Hello <their name>" back to them.

void main() {
    // 1. Call IO.readln to get their name
    // 2. Call IO.print/IO.println to say hello to them
}

Challenge 2

Write a program that asks a person their age and tells them what age they will be this time next year.

void main() {
    // 1. Call IO.readln to get their age
    // 2. Interpret their age as an int
    // 3. Add one to that age
    // 4. Call IO.print/IO.println to say what age they will be next year
}

Challenge 3

Write a program that asks a person for two floating point numbers and tells them what the sum of those two numbers is

void main() {
    // 1. Call IO.readln to get the first number
    // 2. Interpret that first number as a double
    // 3. Call IO.readln to get the second number
    // 4. Interpret that second number as a double
    // 5. Add the two numbers together
    // 6. Call IO.print/IO.println to say what the sum is
}

Challenge 4

"Mad Libs" are a word game where you ask people for nouns, verbs, adjectives, etc. absent any context and then fill them in to a template.

For example

I saw a <noun> today and <past tense verb>.
Unfortunately the <noun> stopped me at the <noun>.

Can become

I saw a dog today and flew.
Unfortunately the clown stopped me at the elephant.

Make a program that asks a user for some nouns, verbs, etc. and prints a Mad Lib using those words.
