That means i has been given an address space in the memory(1000/1001).
Now we are trying to store an address say

like
______________
__00__|___7D__ where 007D is the address of a
1000 1001 float variable.

Now here is my doubt.How compiler knows this assignment is wrong.

int *p = 0x007D;

float k = 10.0;
int *p = &k;

the compiler allocates a certain number of bytes (depending on the platform) on the stack.

struct Data
{
    int number;
    int *pNumber;
};

// Code like this will allocate the memory for a "Data" struct on the stack.
// So the member "number" (not a pointer at all) and "pNumber" (is a pointer)
// will both be allocated on the stack.
void Function()
{
    Data IsOnTheStack;
    // Do stuff...
}

// Code like this will not use the stack.
// The memory will be in a data segment of the executable.
Data InDataSegment; // At global scope.

// Now code like this will place the struct (and its members) on the heap.
// The storage for the actual pointer "pData" may be on the heap, stack or
// a data segment in a module but the actual structure and it members are
// on the heap.
Data *pData = new Data;

This is not always the case: the pointer need not be allocated on the stack.

When i'll doubleclick on an item then save me in a variable the number of the line

int nIndex = pmyListBox->GetCurSel();

So when I doubleclick on an item on 5rd line it gonna give the int value 5 at a variable.
The same variable will be in the command on Winamp for position on Playlist
