This lesson doesn’t introduce any new syntax. Rather, a new technique called nesting is used. Nesting is simply writing code blocks within other code blocks. With even basic programs, it’s necessary to make selections/decisions as a result of some other selection being made.
Example
Console.Write("Would you like to delete your account? ");
string answer = Console.ReadLine();
if (answer == "yes")
{
Console.Write("Are you ABSOLUTELY SURE? ");
answer = Console.ReadLine();
if (answer == "yes")
{
Console.WriteLine("Deleting your account.");
}
else
{
// ... code
}
}
else
{
// ... code
}
It’s so important to keep your code nicely formatted. Here is a review of the tips from before:
if, else if, and else statements that belong together should not have space inbetween them. Butt them right up against eachother so you can see that they’re grouped.This program is called a choose your own adventure game. It’s going to be the biggest program you make so far. Take your time, and test your code frequently. Don’t try to write the whole program and then test it at the end, or else it could spell disaster when you try to debug. Write one section at a time, and then test it.

Upon entering the cave, you see two diverging paths...
Which path do you take? (left or right) -> right
As you leave, you see a delicious Hostess Twinkie.
Do you eat the Twinkie for sustenance, or will you save it for later?
(take or eat) -> take
You never know when a Twinkie will come in handy...
You decide to take the right path.
Later down the trail, you stumble upon an overweight,
repulsive looking talking dragon named Mort the Pudgy.
The dragon speaks: 'Did you bring me snack cakes??'
Do you have a treat to give this foul creature? (yes, no) -> yes
Me love Twinkie!!! Here take gold!
The dragon grants you the gold he was guarding.
How much gold do you take? -> 99
Mortimer the Pudgy grants you his gold...
-- Ending --
By tempting Mortimer the Pudgy with a delicious Hostess snack cake, you avoid his wrath.
He flies you back home after the storm, but not after raiding the nearest Hostess factory.
You survived!!!
You not only survived, but you found 99 gold! Good work!
