Study Notes
Algorithms and Coding
- A programming algorithm is a procedure or formula used for solving a problem, based on a sequence of specified actions.
- Algorithms are the building blocks for programming, allowing devices to function and make decisions.
Loops
- A loop is a sequence of instructions that is continually repeated until a certain condition is reached.
- Loops are used to shorten code, allowing programmers to write it once and repeat it as needed.
- There are three types of loops in Scratch: "repeat", "repeat until", and "forever" loops.
- These loop blocks are found in the "Control drawer" in Scratch.
Input, Process, and Output
- Input refers to the user giving something to the program, while output is the program giving something to the user.
- Input and output is the communication between a computer program and its user.
- Example: inputting R10 into a vending machine and receiving a bag of chips as output.
Flowcharts
- A flowchart is a diagram that represents a workflow or process, showing the steps as boxes of various kinds.
- A flowchart is a picture of the separate steps of a process in sequential order.
- It is a generic tool that can be adapted for a wide variety of purposes.
Variables
- In programming, a variable is a value that can change, depending on conditions or information passed to the program.
- A variable is a way of storing information in a computer program, helping coders understand, remember, and use the information.
- Variables are used to store and retrieve information in a program, allowing coders to use a shortcut instead of remembering strings of information.
