std

#include <bits/stdc++.h>
using namespace std;

int a,b;

int main()
{
    freopen(".in","r",stdin);
    freopen("std.out","w",stdout);
    cin >> a >> b;
    cout << a * b;
    fclose(stdin);
    fclose(stdout);
    return 0;
}

暴力

#include <bits/stdc++.h>
using namespace std;

int a,b;

int main()
{
    freopen(".in","r",stdin);
    freopen("baoli.out","w",stdout);
    cin >> a >> b;
    int ans = 0;
    for (int i = 1; i <= b; i++)
    {
        ans += a;
    }
    cout << ans;
    fclose(stdin);
    fclose(stdout);
    return 0;
}

data

#include <bits/stdc++.h>
using namespace std;

int a,b;

int main()
{
    freopen(".in","w",stdout);
    srand(time(0));
    cout << rand() % 1000000 << " " << rand() % 1000000;
    fclose(stdout);
    return 0;
}

check

#include <cstdio>
#include <cstdlib>
#include <ctime>
#include <bits/stdc++.h>

using namespace std;
int cnt,t1,t2;
int main()
{
    while(cnt <= 10000)
    {
        cnt++;
        
        system("data.exe");
        t1 = clock();
        system("std.exe");
        t2 = clock();
        system("baoli.exe");
        if( system( "fc baoli.out std.out" ) )
        {
            cout << "NO";
            break;
        }
        cout << "#" << cnt << " " << t2 - t1 << "ms" << " " << "YES" << endl;
    }
    
}

include后可以只写万能头文件，其它可以不写
