生成随机数量的随机无重复数

    srand((unsigned)time(0));
    int ran_num = rand()%10+1;//made a rand number([1,10])
    int total[66] = ...{0};
    int i(0);
        do...{
        int x = rand()%66;
        if(total[x]==0)
        ...{
            cout<<x<<" ";
            total[x]=1;
            i++;
        }
        }while(i!=ran_num);
    system("pause"); 
    return 0;

错误之处望不吝赐教。
