    Angry random numbers and responses

    the program asks questions in the same order, how can i fix that?
    for some questions any answer is seen as correct...?

    int main()
    {
    char answer [20];
    char ans = 'y';
    cout <<"Do you know the nicknames of these colleges . . . \n";
    cout <<"All the answers are plural (if possible), lowercase \n";
    cout <<"and do not include the word 'the' \n\n.";
    while(ans == 'y' || ans == 'Y')
    {
    int c=0, w=0;
    while(w + c < 5)
    {
    int choice = randMid(1, 9);

    if (choice == 1)
    {
    cout <<"What is the nickname of The University of Maryland?" << endl;
    cin.getline(answer, 20, '\n');
    if (strcmp(answer, "terps") || strcmp(answer, "terrapins"))
    {
    cout <<"Correct!" << endl << endl;
    c++;
    }
    else
    {
    cout <<"Wrong" << endl << endl;
    w++;
    }
    }

    if (choice == 2)
    {
    cout <<"What is the nickname of Duke University?" << endl;
    cin.getline(answer, 20, '\n');
    if (strcmp(answer, "bluedevils") || strcmp(answer, "blue devils"))
    {
    cout <<"Correct!" << endl << endl;
    c++;
    }
    else
    {
    cout <<"Wrong" << endl << endl;
    w++;
    }
    }

    if (choice == 3)

    c++;
    }
    else
    {

    w++;
    }
    }

    if (choice == 4)
    {
    cout <<"What is the nickname of The University of Virginia?" << endl;
    cin.getline(answer, 20, '\n');
    if (strcmp(answer, "cavaliers"))

    c++;
    }
    else
    {
    cout <<"Wrong" << endl << endl;
    w++;
    }
    }

    if (choice == 5)
    {
    cout <<"What is the nickname of North Carolina?" << endl;
    cin.getline(answer, 20, '\n');
    if (strcmp(answer, "tar heels") || strcmp(answer, "tarheels"))

    c++;
    }
    else

    }

    if (choice == 6)

    if (strcmp(answer, "seminoles"))

    cout <<"Correct!" << endl << endl;
    c++;
    }
    else
    {
    cout <<"Wrong" << endl << endl;
    w++;
    }
    }

    if (choice == 8)
    {
    cout <<"What is the nickname of Clemson University?" << endl;
    cin.getline(answer, 20, '\n');
    if (strcmp(answer, "tigers") || strcmp(answer, "tiger"))

    }
    }
    cout <<"You got " << c <<" correct and " << w <<" wrong!" << endl << endl;
    cout << "Do you want to run this program again? (Y or N) --> ";
    cin >> ans;
    }
    return 0;
    }

    //creates a random number between a low number and high number
    int randMid(int low, int high)
    {
    return low+rand()%(high-low+1);
    }

    You'll have to seed the random number generator -

    srand((unsigned)time(0));

    Include <ctime> to use the time function.

    strcmp() returns zero if the strings are equal.

    i dont understand

    i dont understand after u compare strings how to say if they are equal to do something and if not do something else.
    you said it returns 0 if they are true so can u do an example for one of the parts.

    thanks,
    you're a big help

    if (strcmp(answer, "terps")==0 || strcmp(answer, "terrapins")==0)
