一个C++关于成员变量偏移地址的小Trick
今天看到一个小例子，发现了一个小trick。见代码：
#include <cstdio>
#include <cstdlib>
class base_1
{
public:
int a;
};
class base_2
{
public:
int b;
};
class base_3: public base_1, public base_2
{
public:
int c;
};
int main(int argc, char* argv[]) {
printf("&base_1::a = %p\n", &base_1::a);
printf("&base_2::b = %p\n", &base_2::b);
printf("&base_3::a = %p\n", &base_3::a);…
