I’m combining two tutorials in this post so that whether you are a beginner or an advanced coder this is a great coding challenge for you.
Beginner Challenge 
Generate a Random Number
Generating a random number is used in coding more often than you would think. Because of this, it is actually a lot easier than you would think!
The challenge is to have the user enter a number and then have the app generate a random number between 1 and the number the user entered.

Advanced Challenge 
Generate a Random Dollar Amount
This challenge takes the concept of generating a random number a bit further by adding some additional formatting to the random number.
The challenge is to generate a random dollar amount (ie. $43.96) every time a button is clicked.
