【Cherno的C++视频】Raw pointers in C++

#include 

//a pointer is an integer which stores a memory, 4 bytes,

#define LOG(x) std::cout << x << std::endl;

int main(void)
{
	//int var = 8;
	//void* ptr = nullptr;
	//ptr = &var;

	//int* ptr1 = &var;
	//*ptr1 = 9;
	//LOG(var);

	//double* ptr2 = (double*)&var;

	char* buffer = new char[8];
	memset(buffer, 0, 8);

	char** ptr = &buffer;

	delete[] buffer;

	std::cin.get();
