where is struct field that created by new (heap or stack)?

i read about stack and heap but i don't know about this

where is x ( in heap or in stack ) ? is my code have a memory leak or not ?

struct st
    int x;
    int* y;

st* stp;

void func()
    st* s=new st();

    s->y=new int(5);


int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])


    cout << stp->x << "  " << *stp->y <<endl;

    delete stp->y;
    delete stp;

output 2 5


stp is dynamically-allocated, and is therefore on the heap.* Therefore, all its members (including x) are on the heap.

As far as I can see, you don't have a memory leak.

* Technically, the C++ standard doesn't talk about stack vs. heap, so it's up to the compiler where stuff gets allocated. But in practice, it will be stored in a heap-like structure.
