我在XCode 6.3.2中收到此错误:

循环最多运行一次(循环增量从未执行)

我试过for (int prob = 0; prob < response; prob++)并收到了同样的错误.

        int response = ' ';
        cout << "How many equations would you like to do? \n";
        cin >> response;

        for (int prob = response; prob > 0; prob--)
        {
            cout << "Calculate the following equation: \n";
            correct = rand() …
