Scratch and programming Control Structures

This set up allows us to click anywhere on the white page and the dog will move to the x and y co-ordinates of the cursor.





This set up is the same as the previous one but there is one more step to it. When you click anywhere on the white page the dog will move to the x and y co-ordinates of the cursor and also will make a "woof" sound.

Flowchart - Opening a door and entering a room





Sample Flowcharts

Flowchart 1) This flowchart is showing when you click the start button, it then reads the temperature. Then you have a option of either yes or no, if the temperature is less than 32. If you say yes it will print out below freezing, if you say no it will print out above freezing, then the process ends.

Flowchart 2) This flowchart is showing that when you click on the switch, it will trigger it to start and then a timer will start as well, once it 1 second has expired it will turn off and the timer will reset and that is the end of it.

Computer Algorithms

1.       Algorithms: An algorithm is a set of instructions, sometimes called a procedure or a function, that is used to perform a certain task. This can be a simple process, such as adding two numbers together, or a complex function, such as adding effects to an image.
2.       Pseudocode: Pseudocode is an informal language, so it is mainly used for creating an outline or a rough draft of a program. Because it is not an actual programming language, pseudocode cannot be compiled into an executable program.  
3.       Machine Language: computer language: a programming language designed for use on a specific class of computers.
4.       High Level Computer Language: a problem-oriented programming language, as COBOL, FORTRAN, or PL/1, that uses English-like statements and symbols to create sequences of computer instructions and identify memory locations, rather than the machine-specific individual instruction codes and numerical addresses employed by machine language.
5.       Flowchart:  a diagram of the sequence of operations in a computer program or an accounting system.
6.       Sequence: Sequence is the default control structure; instructions are executed one after another.
7.       Selection: In a selection structure, a question is asked, and depending on the answer, the program takes one of two courses of action, after which the program moves on to the next event. This structure is sometimes referred to as an if-then-else because it directs the program to perform in this way: If Condition A is True then perform Action X else perform Action Y.
8.       Repetition: The process of repeating a set of instructions a specified number of times or until a specific result is achieved.
