程序代码：

int main()
{
        srand(time(NULL));
        int num;
        while(cin >> num)
        {
                int r = rand()%2; //产生随机数，如果r=1就输出+,否则输出-
                if(num >= 0 && num <= 9)
                {
                        cout << (r == 1 ? "+" : "-");
                        if(num == 0)
                                cout << 100 << '\n';
                        else
                                cout << num * 10 << '\n';
                }
        }
}

不知道是不是理解对了你的题目意思
