You need to break down your problem in smaller pieces. Here is a suggestion of some helper functions to get you started.
digit->image : number -> image Given a digit (0,1,...,9) as input, return an image of that digit. number->digits : number -> listof-numbers Given a natural number return a list of the digits Example: (number->digits 123) evaluates to (list 1 2 3) digits->image : list-of-numbers -> image Given a list of numbers return an image where the digit images are glued together horisontally. time->image : number number -> image Given two number an hour and a second return an image which shows the two numbers with an : between them. /Jens Axel 2016-10-14 8:12 GMT+02:00 Masto Fine <thomaspierrard1...@gmail.com>: > je commence en drracket et je cherche qqun qui pourrait m'aaider pour l > construction de petits programmes ! > j'en suis par exemple a la construction de petits mondes , et je ne > comprends pas comment programmer la differences entre une evolution > spatiales (avec l'axes des abscisses , ordonnees ) comme dans l'exemple de > mon manuel ; et une evolution numerique " en valeur absolue" comme dans > l'exercice que je dois realiser : construite une horloge numerique. > l variable mathematiue ne me pose pas de problemes , c'est juste au > moment de programmer l'evolution numerique dans l discretisation du monde , > ou la programmation monde -monde ou celle monde-image que je peche . > Pouvez vous m'aider. > > -- > You received this message because you are subscribed to the Google Groups > "Racket Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to racket-users+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- -- Jens Axel Søgaard -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
