Challenge of the Month - October 2016

    General discussion

  • These challenges are intended for people who are learning to program for the first time or for those returning to programming who want to start using Small Basic.  Some will be easy, some will be hard - but they will all make you think, and more importantly be GREAT FUN!

    Please post your solutions / partial solutions / questions / feedback etc. into this thread that will remain 'sticky' for the month.  The only rule is that your solution must use standard Small Basic methods (no extensions).

    It would be good if people could post their problems with these challenges so that a discussion can start so that everyone can learn from each other.

    We may extend these challenges over into a second month if solutions and questions are still coming in.

    Text Challenge

    • Write a program to format numbers 1 to 100 in a neat 10 by 10 grid in the TextWindow
    • Modify the program to colour numbers divisible by 5 red, and numbers divisible by 7 yellow.

    Graphics Challenge

    • Make an animation of a spinning top rotating and moving in the GraphicsWindow

    Colourful Spinning Top - Discontinued

    Game Challenge

    • Write a noughts and crosses game to play against the computer
    • Perhaps add some nice graphics and sound effects to the game


    Maths Challenges

    • Write a program to calculate the change in the correct coinage of your currency.  Perhaps randomly set a price of something and ask the user to enter the money given and the program works out the correct change.

    For example:

    Item costs £2.65 and user gives £5. 

    The change is:

    1 £2 coin

    1 20p coin

    1 10p coin

    1 5p coin

    • Write a program to calculate the sum of the first 100 prime numbers

  • @NaochanON

    thanks !    have you like the sound effect for each turn?

    yes, it's only a you can win version, computer start allways at the center.

    One day, when I get to know SB a little more, I will re - write my program but in a more mathematical way,

    to  keep track of the current 'state' of the game by using ' two dimensional arrays' like (1,1) to (9.9).
