凤凰大街想hi地讲没第老宋毛细血孔老搜搜谬赞这滴你休息叫自信好的好的度发酒疯就到家

#include <iostream>
using namespace std;

int main() {
    int sum = 0; 
    int count = 0;
    for (int i = 1; i <= 1000; i++) {
        if (i % 7 == 0) {
            sum += i;
            count++;
            cout << i << " ";
            if (count % 5 == 0) {
                cout << endl; 
            }
        } 
    }
    cout << "sum = " << sum << endl;
}

输出结果:

7  14 21 28 35 
42 49 56 63 70
77 84 91 98 105
112 119 126 133 140
sum = 455
