把i存进一个数组

yuandingquan说的对 是：

#include <iostream>
using namespace std;

int a[4000];

int main()
{
    int x, y, cnt = 0, cur = 0;
    cin >> x >> y;
    // 注：register对代码没影响
    for (register int i = x;i <= y;i++)
    {
        if (i % 4 == 0 && (i % 100 != 0 || i % 400 == 0))
        {
            cnt++;
            cur++;
            a[cur] = i;
        }
    }
    cout << cnt << endl;
    for (int i = 1;i <= cur;i++)
    {
        cout << a[i] << " ";
    }
    return 0;
}
