最佳答案
一个简短的例子输出一个奇怪的结果!
#include <iostream>
using namespace std;
struct A { int a; };
struct B { int b; };
struct C : A, B
{
int c;
};
int main()
{
C* c = new C;
B* b = c;
cout << "The address of b is 0x" << hex << b << endl;
cout << "The address of c is 0x" << hex << c << endl;
if (b == c)
{
cout << "b is equal to c" << endl;
}
else
{
cout << "b is not equal to c" << endl;
}
}
令我非常惊讶的是,结果应该是这样的:
The address of b is 0x003E9A9C
The address of c is 0x003E9A98
b is equal to c
让我想知道的是:
0x003E9A9C 不等于0x003E9A98,但是输出是“ b 等于 c”
