c - memory allocation in Stack and Heap -

-

this may seem basic question, been in head so:

when allocate local variable, goes stack. dynamic allocation cause variable go on heap. now, question is, variable lie on stack or heap or reference in stack , heap.

for example,

suppose declare variable int i. i allocated on stack. so, when print address of i, 1 of location on stack? same question heap well.

i'm not entirely sure you're asking, i'll try best answer.

the following declares variable i on stack:

int i;

when ask address using &i actual location on stack.

when allocate dynamically using malloc, there two pieces of data being stored. dynamic memory allocated on heap, , pointer allocated on stack. in code:

int* j = malloc(sizeof(int));

this allocating space on heap integer. it's allocating space on stack pointer (j). variable j's value set address returned malloc.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
