  1. In Topic: how do I create a strike through in an array when the word is clicked

    Posted 4 May 2015

    This looked amusing enough I thought I'd take a stab at it. It also struct me that the toggle could be generalized.
  2. In Topic: Need help with 2D arrays and out putting decimal points - Homework

    Posted 3 May 2015

    Heh, I wasn't critiquing the description style. Rather, the recommended approach is poor. Using a 2D array as a kind of table of of data, with one dimension being rows and each column being a different field is messy, confusing, and teaches bad habits.

    The proper approach for "read data of type X from file, perform actions using elements of that type, and display results Y" would be to define a type X and go from there.

    struct Batter {
        int playerNum;
        int appearances;
        int hits;
        int walks;
        int outs;
        double getAverage() const;
    typedef std::vector<Batter> Batters;
    void display(const Batter &);
    void display(const Batters &);
    int load(Batters &, std::istream &);
    int load(Batters &, const char *filename);

    You reasonably should cover std::vector and struct before messing with std::ifstream.
  3. In Topic: Need help with 2D arrays and out putting decimal points - Homework

    Posted 3 May 2015

    There is no reason you should store the average in the array. Your instructions suck, you shouldn't be using a 2D array at all, but at least they don't tell you to do that.

    I would do something like:
    // First column is player number, second column is plate appearances, 3rd is hits, 4th is walks, and last is strike outs.
    const int COLS = 5;
    // note, an enum would be helpful for the cols...
    const int MAX_ROWS = 10;
    typedef int Batters[MAX_ROWS][COLS];
    double calcAverage(Batters, int rowNum);
    void displayBatters(Batters, int rows);
    int load(Batters, std::istream &);
    int load(Batters, const char *filename);
    int main() {
        Batters batters;
        int rows = load(batters, "batters.txt");
        if (rows==0) { return 1; }
        displayBatters(batters, rows);
        // system ("pause");
        return 0;
    void displayBatters(Batters ar, int rows) {
        for(int row = 0; row < rows; row++) {
            for(int col = 0; col < COLS; col++) {
                cout << ar[row][col] << " ";
            cout << calcAverage(ar) << endl;

    Hope this helps.
  4. In Topic: How to initialize a variable only once?

    Posted 3 May 2015

    public void addNewSong() {
        Song song1 = new Song();
        Song song2 = new Song();
        Song song3 = new Song();
        Song song4 = new Song();

    You see those, the are ALL local variables. So, assuming you've defined the same variables somewhere in your object, you ain't writing to them. Also, your input code is repeated over and over...

    Consider the following method:
    private Song getFromUser() {
        Song song = new Song();
        System.out.println("Name of song:");
        // consider returning null here if the user enteres a blank line
        // no empty song titles!
        System.out.println("File size (MB):");
        System.out.println("Duration (seconds):");
        System.out.println("Song successfully added.");
        return song;

    That gets a loaded Song object from the user. There is no conceivable reason to have an isEmpty method in your song, you just don't let the user enter blanks. For your program, you can do something like:
    class SongDatabase {
        // these belong here
        private Song song1, song2, song3, song4;
        public void addNewSong() {
            if (song1==null) {
                song1 = getFromUser();
            } else if (song2==null) {
                song2 = getFromUser();
            } else if (song3==null) {
                song3 = getFromUser();
            } else if (song4==null) {
                song4 = getFromUser();
            } else {
                System.out.println("The database is currently full. Please delete a song before adding a new one.");

    Hope this helps.
  5. In Topic: operator<< overloading

    Posted 2 May 2015

    I would avoid the friend functions and throw the operator override outside, if you are allowed. e.g.
    #include <iostream>
    class Thing {
        Thing(const std::string &name);
        virtual void print(std::ostream &) const;
        const std::string &getName() const;
        std::string name;
    class Thing2 : public Thing {
        void print(std::ostream &) const;
    struct Thing3 : public Thing {
    std::ostream &operator<< (std::ostream &, const Thing &);
    int main() {
        std::cout << Thing("Bob") << std::endl;
        std::cout << Thing2() << std::endl;
        std::cout << Thing3() << std::endl;
        return 0;
    std::ostream &operator<< (std::ostream &out, const Thing &x) { x.print(out); return out; }
    Thing::Thing(const std::string &n) : name(n) { }
    void Thing::print(std::ostream &out) const { out << "Thing [" << name << "]"; }
    const std::string &Thing::getName() const { return name; }
    Thing2::Thing2() : Thing("Thing2") { }
    void Thing2::print(std::ostream &out) const { out << "The amazing Thing2 [" << getName() << "]"; }
    Thing3::Thing3() : Thing("Thing3") { }

    Hope this helps.

    I agree with assert(C). However, I'd rather not specify what you are "the best" at.
