1022 D进制的A+B c++测试点三

测试点三就是输入为0 0的时候

#include
using namespace std;
int main() {
	int a, b, d, sum;
	int z[40] = {0}, n = 0;
	cin >> a;
	cin >> b;
	cin >> d;
	sum = a + b;
	while (sum != 0)
	{
		z[n++] = sum % d;
		sum = sum / d;
	}
	if (sum == 0)
		cout << 0;
	else
		for (int i = n - 1; i >= 0; i--)
			cout << z[i];
	return 0;
}
