Exercise: 5. Draw 40 small circles starting at the middle left of the screen extending to the middle right of the screen. Make each circle a random color. left question at school, in case you guys know how. I'll write up a new one, editing this thread soon. |

Are you asking us to program it for you? |

No var circleCount : int var circleColour : int var x : int var y : int y := maxy div 2 x := 15 circleCount := 0 loop randint (circleColour, 1, 255) Draw.FillOval (x, y, 15, 15, circleColour) circleCount := circleCount + 1 x := x + 15 end loop I need to know how to make it 40 circles. |

the infinite loop will make an infinite amount of circles. do you know how to repeat a fixed number of times? hint: try a different type of loop |

or in case they dont know already... Basically every language has a structure called a for loop, which loops for only a specific amount of iterations. In this case, it's structured like this: for i : 1 .. n end for i being what you want to call the loop, and n being the number of times for it to iterate. |

if you want to keep the code you have use an exit when statement (Ex. exit when Letter = "a") |

Or, you know, teach him a much better concept |
