char a = 'b';
int *p = (int*)&a;

class A {};
class B {};
A * a = new A;
B * b = reinterpret_cast<B*>(a);

reinterpret_cast answer was a TOTAL BULL SHIT !!
The answer before was even more DUMBEST!!! BOTH THOSE TWO GUYS MUST BE SHOT TO DEATH, OR, their rib bones must be ripped off and shoved in their respective fucking eyeballs!!! How dare they be stupid here?

void pointtoother(void** d)
{
char* s = (char*)malloc(sizeof(char));
*d = s;
}

char* p = "all_answers_are_dumb_ass_here";//p points to an unnamed array
pointtoother( &p );
//when the call returns, p will be pointing to somewhere else

void PointerToOtherObject(void** pointer, void* otherObject);	// Function prototype perhaps not needed.

void PointerToOtherObject(void** pointer, void* otherObject)  // Parameters are the pointer to be modified and the object that the pointer will point to after the function call.
{
	*pointer = otherObject; // store the object's address within the location of pointer
}


void main(void)	
{
	char* stringObject = "This is a string. ";
	int intObject = 256;
	void* genericPointer = stringObject;   // Assign the pointer to point to the string object.
	PointerToOtherObject(&genericPointer, &intObject); // Call our function to change the pointer to point to the "other object", in this case, an integer.
	// genericPointer now contains the intObject's address. ie, points to the int instead of the character string
