What are Preconditions?
Things we knew before starting this class
Assumptions about what must be true before the function is called.
Libraries that must be called for our code to execute
What should be true after the function is called
2
What are Postconditions?
Instructions provided by a developer on the outcomes of a process
Assumptions about what must be true before the function is called.
Code that has to be run after initializing a block of code
What should be true after the function is called

What does it mean to Define a function?
teach the computer a new command & explain what it should do w/that command
put a comment before a function that explains what it is supposed to do
hard-coding the definition of variables
write the instructions for what you want code to do
10
What does calling a function do?
gives the command, so the computer will run the code for that function.

13
What are Application Programming Interfaces?
APIs and libraries simplify complex programming tasks
The devices we use to interface with computers such as mice or keyboards

16
Procedural Abstraction is...
The ability to use methods and programs that we do not fully understand
