Assign constructor parameter to object variable - Delphi -

-

this question has answer here:

i keep getting error dialog:

access violation @ address xxxx in module 'xxxx.exe'. write of address xxxx.

what should do?

constructor tcustomclass.create(id: integer); begin   self.id := id; end;

any thoughts?

the odds problem you're calling constructor incorrectly. you're doing similar following:

var   linstance: tcustomclass; begin   linstance.create(1);   ... end;

the problem linstance doesn't exist yet, you're calling method on it. need create instance follows: linstance := tcustomclass.create(1);

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
