数据

#include<bits/stdc++.h>
#include<sys/timeb.h>
using namespace std;
typedef long long ll;

ll Rand(ll mod)
{
    ll ans = INT_MAX;
    return ans * rand() % mod + 1;
}

int main()
{
    struct _timeb T;
    _ftime(&T);
    srand(T.millitm); // T.millitm 为毫秒级随机数的种子
    mt19937 rd(T.millitm); 
    ofstream file;
    file.open("a.in");
    int a = rd(), b = rd();
    file << a << ' ' << b;
    file.close();
    return 0;
}

或者：

#include<bits/stdc++.h>
#include<sys/timeb.h>
using namespace std;
typedef long long ll;

ll Rand(ll mod)
{
    ll ans = INT_MAX;
    return ans * rand() % mod + 1;
}

int main()
{
    struct _timeb T;
    _ftime(&T);
    srand(T.millitm);
    mt19937 rd(T.millitm);
    freopen("a.in","w",stdout);
    int a = rd(), b = rd();
    cout << a << ' ' << b;
    return 0;
}

暴力

#include<bits/stdc++.h>
using namespace std;
int main()
{
    freopen("a.in", "r", stdin);
    freopen("a.out", "w", stdout);
    int a, b;
    scanf("%d%d", &a, &b);
    printf("%d\n", a + b);
    return 0;
}

待测

#include<bits/stdc++.h>
using namespace std;
int main()
{
    freopen("a.in", "r", stdin);
    freopen("a.ans", "w", stdout);
    int a, b;
    scanf("%d%d", &a, &b);
    printf("%d\n", a + b);
    return 0;
}

    return 0;
