8 Home Back Next Computer Programming Home What is “R.E.S.O.L.V.E.?” Computer Programming: “A set of coded instructions that enables a computer to perform a desired sequence of operations” We communicate to exchange information: The language we use is determined by –Who- or –What- we’re talking to… If we use different languages… Or don’t speak clearly--- We won’t be able to understand each other… Intro HelpQuit Programming Concepts Practice

9 Home Back Next Home Computers speak a special language - called BINARY CODE Electronic impulses within the computer’s hardware register as “1’s” and “0’s” They turn ON and OFF in patterns and sequences that communicate an action. The computer then performs that action. If we were to give the computer instructions in ‘binary code’ it would take a LONG time to get any computer work done… Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

10 Home Back Next Home Computer programmers use a special computer language to communicate with computers… That language is translated into BINARY CODE so that the computer can understand what to do… Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

11 Home Back Next Home The computer programmer MUST write the code correctly – or there is NO communication! (‘LOGO’ written backwards!) Uh …??? Okay – what do we know? Using the correct language allows us to communicate so that we understand each other Writing a computer programming language correctly helps the computer understand what we need it to do! Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

12 Home Back Next Home Writing Commands = code + syntax Sequencing Commands & Procedures Writing Procedures Conditional and Control Statements Error Messages Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

13 Back Next Writing commands–Part 1 LOGO commands have certain rules: Follow correct formatting--> Command _ space _ input (ex: setc 9) Watch your spelling (ex: ‘carefully’ ) Make sure you use the correct punctuation (ex: ‘newturtle’ required “ in front of the turtle’s name) Make sure you use the inputs that are allowed (ex: setpensize can only go up to a certain number. Can you experiment and figure out which rules are being used in the “cleanup” procedure? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

14 Back Next Writing commands–Part 2 Writing commands CORRECTLY also means that you understand what they do: Example #1: Random selects from a range of actions. You must FIRST give it the action! (ex: ‘fd random 30’ vs. ‘random 30’) Example #2: There are only 139 colors (with ‘0’ being white). If you go BEYOND 139 MicroWorlds begins again at ‘0’ (ex: setc 145 is the same as setc 6) Now how did I figure that out? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

15 Back Next Writing Procedures-Part 1 PROCEDURES follow five main rules: Always begin with the word “to” Always end with the word “end” Don’t use command words as procedure names Name of a procedure should be ONE word with no spaces Procedure names should be logical – you should know what’s going to happen by it’s name How many procedures are there in this example? Do they follow all the rules? Why? Or why not? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

16 Back Next Writing Procedures-Part 2 PROCEDURES can be sequenced within other procedures. EX: “many_weird” is a procedure that makes 50 ‘make.design’ procedures A procedure made up ONLY of other procedures is called a SUPERPROCEDURE EX: It contains no commands, only other procedures Could you use these commands to create your own ‘SUPERPROCEDURE?’ Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

17 Back Next Sequencing Commands and Procedures There are 3 boat sub-procedures in this program: Set_boat Boat_go Boat_float * Boater is a SUPER-PROCEDURE that runs the three sub procedures one at a time – Automatically! The order in which the commands are listed determines the order in which the action occurs! Is the order of procedures in a SUPER-PROCEDURE also important? Why? Or Why Not? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

18 Back Next Sequencing Commands and Procedures The boat in this example appears to be rowing up into the trees! Look at the SUPER-PROCEDURE -> “Boater” * Which sub procedure is missing from before? RIGHT! “Set_boat” is not included in the “Super” Without it in the sequence the boat can’t:  turn in a angle  Pick up it’s pen (see the black line?)  Set it’s X and Y coordinate position on the screen. No wonder it’s floating in mid-air! Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

19 Back Next Conditional/Control Statements Home The “Question” command needs a partner “Answer” The “QUESTION” is within brackets QUESTION brings up a box that waits for the user’s response ANSWER checks to see if the user’s response matches the choices offered Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice - 1 -

20 Back Next Conditional/Control Statements Home If more than one ANSWER option is provided: The computer checks them in the order that they are listed In this example, ANSWER won’t find “frog” because the user chose to answer “whale” Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice - 2 -

21 Back Next Conditional/Control Statements Home Hmm …”forg?” In this example the user’s response has to look EXACTLY like the answer statement. It checks for “frog” - not found! It checks for “whale” - not found! Moving down the line, the program runs the NEXT line of code which is the “ask_again” procedure “ASK_AGAIN” makes a statement; then runs the “water_animals” procedure again. Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice - 3 -

22 Back Next Common Error Messages “I don’t know how to ‘to’…” Procedure missing “to” or “end” error “ ‘wait’ needs more inputs…” Needs more input error “I don’t know how to ‘repaet’” Spelling errors “I don’t know how to ‘fd10’” Missing space error “answer = “NervousRex is not true or false in joke” Syntax error (code written improperly) (click on an error message for more information!) Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

23 Back Next Common Error Messages Procedure missing “to” or “end” error EVERY procedure needs two things: Start with the word “to” End with the word “end” The “make_triangle” procedure is missing one of these. The logo turtle can’t start the “make_square” procedure without it. Can you guess which it is? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

24 Back Next Common Error Messages Spelling Errors Computers programming languages only know what you SAY, not what you ‘mean!’ Microworlds need you to speak its language – It can’t spell check It can’t figure out what you mean Spelling errors one of the most common programming code errors! Can you figure out which word is misspelled? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

25 Back Next Common Error Messages Needs more input error Writing commands takes on a certain rhythm. In this case it’s COMMAND _ space _ INPUT Write the command Press the spacebar Tell the computer how MUCH “Wait” is looking for the amount of time you want the turtle to wait. You need a number! HINT: every number is 1/10 of a second: “Wait 10” will cause the action to wait one second. Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

26 Back Next Common Error Messages Missing space error The writer of this code has lost their rhythm! The sequence is: Command _ SPACE _ Input Write the command PRESS THE SPACEBAR Tell the computer ‘how much’ (ex: setc 32) Hmm…!!! One of the commands in this procedure is missing it’s –SPACE- Can you guess which it is? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

27 Back Next Common Error Messages Syntax error (code written improperly) The Question/Answer sequence requires very specific characters. Brackets around the question [] Parentheses around (answer = ) Brackets around what happens if the user provides the answer listed [] This “question” or “answer” command is using the wrong symbols. Can you guess which one it is? Home Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

28 Home Back Next Home Conditional & Control Statements If (answer = “yes” [CorrectAnswer stop] Writing commands setc 1 + random 139 Writing Procedures… To square Repeat 4[fd 100 rt 90] end (Expert: “Hmm…why did that happen? What if I…”) Using “R.E.S.O.L.V.EUsing “R.E.S.O.L.V.E.” Computer Programming What is “R.E.S.O.L.V.E.?” Intro HelpQuit Programming Concepts Practice

29 The “joke” procedure on the right is FULL of errors! (can you see them? There are “6” in all…) Let’s see how using the R.E.S.O.L.V.E.
