2个错误
1:由于物品为4位的数字,而你用int接受之后,会舍弃前面的0,要么你改用string,要么用iomanip里的函数或者printf控制输出
2,换行的问题,如果某个学生没有违禁物品,就不用输出他的信息(k仍为1);

    map<string, int> mp;
    for (i = 0; i < M; i++)
        cin >> check[i];
    for (i = 0; i < N; i++) {   //N个学生 
        int k = 1;
        cin >> name >> n;
        for (j = 0; j < n; j++) {
            cin >> tem;
            for (t = 0; t < M; t++) {
                if (tem == check[t]) {
                    goods++;    
                    if (k == 1) {  
                        k--;
                        cout << name << ":";
                    }
                    if (k == 0)
                        cout << " " << setw(4) << setfill('0') << tem; //ERROR 1
                    if (mp[name] == 0) {
                        mp[name]++;
