为啥不能输出none，就是希望那个如果范围内没有水仙花数就输出none有的话输出水仙花数就行了

Question

Answer 1

for (int i = m; i <= n; i++) {
    a = i % 10;
    b = i / 10 % 10;
    c = i / 100;
    if (i == a * a * a + b * b * b + c * c * c) {
        cout << i << end1;
    }
    else {
        cout << "none" << end1;
    }
}

你试试for循环里面这样写
