除法运算没有给出正确的结果

Question

我对这个操作有问题，它并没有真正给出正确的结果。 结果在终端上是60216，但应该是563376.

int a = 8536;
int b = 563376;
int d = 8536;
unsigned long long int k = (a*b);
cout << k/d << endl;

Answer 1

到处都需要long long

long long int a = 8536;
long long int b = 563376;
long long int d = 8536;
unsigned long long int k = (a * b);
std::cout << k / d << std::endl;

请注意，这与除法无关。这个

int a = 8536;
 int b = 563376;
unsigned long long int k = (a * b);
std::cout << k  << std::endl;

也答错了
