指针值不同,但它们相等。为什么?[转]
#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;
}
}
原因:不同类型的指针会进行隐式类型转换。
