    <p>I want to create a SDL-based Hanoi Tower Game, but before I proceed to writing "engine", I wanted to test my Hanoi in a console. Surprisingly, it turned out to be quite buggy.</p> <pre><code>CTower tower[3]; tower[0] = CTower(3); tower[1] = CTower(3); tower[2] = CTower(3); init(&amp;tower[0]); //prepare first tower tower[0].Print(); </code></pre> <p>This piece of code should create 3 arrays (of size 3) and fill 'em with 0 (zeros). Then, in init(), I prepare the first tower (fill it with vaild discs). However simple may it seem, my application halts on printing and doesn't fill the remaining arrays (with 0). What's strange, function init() works just fine.</p> <p>I would appreciate any help. </p> <p>Here's some code to check:</p> <pre><code>class CTower { uint16 *floors, floorsNum; void Init(); public: (...) //definitions, probably of zero importance }; void CTower::Init() { //private member, filling with zeros for (uint16 i = 0; i &lt; floorsNum; i++) floors[i] = 0; } CTower::CTower() { //default initialiazer floors = NULL; floorsNum = 0; } CTower::CTower(uint16 nfloors) { floors = new uint16[nfloors]; floorsNum = nfloors; this-&gt;Init(); } CTower::~CTower() { delete[] floors; floorsNum = 0; } void CTower::Print() { if (floorsNum == 0) printf("EMPTY TOWER!"); else for (uint16 i = 0; i &lt; floorsNum; i++) printf("%d\n", floors[i]); } void init(CTower *tower) { //a friend method of CTower for (uint16 i = 0; i &lt; tower-&gt;floorsNum; i++) tower-&gt;floors[i] = i+1; } </code></pre> <p>My application source: <a href="https://rapidshare.com/files/2229751163/hanoi-tower.7z" rel="nofollow">https://rapidshare.com/files/2229751163/hanoi-tower.7z</a></p>

    1. COI think your `};` of the class should be at the end, i.e. after of the methods.

    2. COYou could also put a break point on the print method and find out what value `floorNum` has.

    3. COWould you mind showing the `init` function as well? Also, have you tried stepping through the code in a debugger?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
