----------------------------------- atrain Thu Mar 03, 2005 11:16 pm Removing an item in an array ----------------------------------- i have to make a program which keeps track of things... I want things to be added and subtracted... i hear a flexible array can let the array be added to, but can i delete arrayvar (2) and have everything else shift down?? im willing to move everything down, then delete the last one 2... so how would i go about doing this? (adding + subtracting) ----------------------------------- jamonathin Fri Mar 04, 2005 6:59 am ----------------------------------- colorback (black) color (white) var file, maxnum : int := 10 var numbers : array 1 .. maxnum of int var choice : string for i : 1 .. maxnum numbers (i) := i * 3 end for proc table cls for i : 1 .. maxnum locate (i, 1) put i, ". ", numbers (i) end for end table loop table put "Select a file number" get file put "What do you want to do, (w)rite, (d)elete, (q)uit?" get choice if choice = "w" then put "Enter a number" get numbers (file) elsif choice = "d" then if file not= maxnum then for i : file .. maxnum - 1 numbers (i) := numbers (i + 1) end for end if numbers (maxnum) := 0 else exit end if end loop Also look under tutorials under high score for more help on this. ----------------------------------- Bacchus Fri Mar 04, 2005 7:01 am ----------------------------------- read the flexible array tutorial on how to delete certain parts of it. its by Cervantes and he explain how to do that very well ----------------------------------- atrain Fri Mar 04, 2005 1:04 pm ----------------------------------- where is this tutorial that you speakith of? ----------------------------------- Tony Fri Mar 04, 2005 1:49 pm ----------------------------------- where is this tutorial that you speakith of? [url=http://www.compsci.ca/v2/viewtopic.php?t=6723]Internet -- same place where every other Turing tutorial is. ----------------------------------- atrain Fri Mar 04, 2005 4:44 pm ----------------------------------- k, i see how to do it... thanks all!!! 1 other question: if i set new Array, current - 1 then it will properly delete an item?? ----------------------------------- Tony Fri Mar 04, 2005 5:18 pm ----------------------------------- Exactly. If you need to get rid of an item in an array, just swap it with the last element and decrease the size by one. :) ----------------------------------- atrain Sun Mar 06, 2005 4:41 pm ----------------------------------- yup it works fine... Thanx soo much now only problem is my program is so huge, it doesnt have enougf memory to indent!!! stupid wine!!! ----------------------------------- McKenzie Sun Mar 06, 2005 4:43 pm ----------------------------------- Turing will also stop indenting if you have even a single line that is too long. Check for that before you give up on the auto-indent. ----------------------------------- Bacchus Sun Mar 06, 2005 5:52 pm ----------------------------------- copy selections of the code and paste them into a new turing file to indent it then just copy and paste that back into the main file. always did that at school and worked just fine ----------------------------------- atrain Sun Mar 06, 2005 7:53 pm ----------------------------------- by ine that is too long, do you mean like a loop / if statment inside a loop inside a loop and on and on, so that the indent would be huge or the line has 2 much text on it, and i have to split it up if possible??? i manualy indented it this time, but my code will just continue growing... i got rid of all big lines... my program is 453 lines long... ----------------------------------- Cervantes Sun Mar 06, 2005 8:18 pm ----------------------------------- There shouldn't be any problem with 453 lines. Probably you've got some really long lines. Try splitting them up. ----------------------------------- atrain Thu Mar 10, 2005 10:03 pm ----------------------------------- ive split up long lines... im pritty sure it has to do with the fact that im on wine... i wish theyed make a version of turing for linux already (i hear there is one, but not sure how resent it is..)
