Control Structures

Control structures are things you can put in your code to perform various logic operations. (i.e. perform a line of code multiple times)

There are a few but there are 2 important ones to know:

• if statments
• for loops

if Statements

Functions

Each function has

• parameters (what variables the function takes)
• return type (what the fucntion returns, if anything)

// No return type
func printNum(num: Int) {
 print(num)
