A Computer Program Is Just a Recipe
- Programs are recipes telling computers how to “cook” data.
- Programs have ingredients & instructions.
- Ingredients in a program are like boxes.
- Each box has a unique name.
- Each box has a data type.
- Boolean data type
- Character data type
- Integer data type
- Float data type
- Box = Variable
- Value of a Variable
- Primitive data types
- Data structures
- Arrays
- Array of integers
- Array of characters
- Strings
- Declaring a variable
- Assigning a value to a variable
- Assigning a new value to a variable
- Ingredients of a program are variables. What are instructions?
- An assignment is one kind of instruction.
- A print statement is another kind of instruction.
- A simple program: Just a print statement
- Another simple program: An assignment and a print statement
How Computers Store Data
- Computers Can Cook Data, but We Have to Write the Recipes
- Computers Remember and Do Things Kind of Like Us
- Computers Use Secret Codes Called Data Types to Store Data Using 0s and 1s
- Boolean — Yes and No
- Boolean — Housing the Truth
- Houses of Character
- Computers Use Blocks of Memory to Represent Larger Pieces of Data
- Liar Paradox or a Joke for Computers
