This section is all about making decisions in our algorithms.
But I want to start with going over something we missed before but will be very important in this section
and feature sections.
So we saw in our main function here that we have these braces or curly braces here around all our statements.
So remember what a statement is it's something that always ends in a semi-colon.
So for example RCO statement here is an example of a statement and we have this other thing up here
called the declaration which just means hey compiler I'm going to be using something called x.
So we created this variable x this identifier x and we'll be using it later.
So but we don't have a value associated with it yet.
So that's that's a declaration.
So these braces are used to group declarations and statements together into what's called a compound
statement.
So this whole thing is one compound statement.
It's also called a block.
So you can think of all these statements belonging to this block.
So who knows.
We don't have a semi-colon at the end of the right brace because we don't need it.
This is an the braces themselves aren't a statement but everything in it is.
So you'll see these a lot with the different control structures that we'll be using in our upcoming
lectures.
