распределение памяти приятеля

The program should do the following:

1. Reserve a memory array (like int*) that is constructed by the constructor of the Allocator class. For example, this function can be realized as follows:

Allocator(int max_size) 

{ 

memory = new int[max_size]; // it is a private variable

_max_size = max_size; //it is a private variable

}

Note, that max_size should be a degree of 2.

Also, the destructor ~Allocator() should be realized too.

2. Alloc a piece of the reserved memory as follows:

void* Alloc(int max_size)

{

 // here should be the function's body

}

3. Free a piece of the memory reserved early as follows:

void Free(void * memory_ptr)

{

 // here should be the function's body

}
