  1. In Topic: C++ book for C programmers

    I find it boring since I already know the basics of C.

    Um, tough. ;)

    C and C++ are very different languages. You are much better off going in with that in mind and learning C++ from chapter one. If you think "I know all this already" you are pretty much setting yourself up for frustration failure.

    If you've already learned a programming language, then you should have the feel for how a good book is laid out. You learn the structure of the language. The fundamental data types. The flow control. The statements that form the core of the language. The functions and libraries most commonly used. Examples of problem solving.

    If you're an experienced programmer, you can learn the structure of most languages fairly quickly. Maybe even in that mythical 21 day or even 24 hour window. However, after that is actually using it effectively and that will take much longer.

    Note that in terms to structure, C is very simple language. Conversely, C++ is a gigantic hot mess that will take a long time to get a handle of all the syntax, if anyone ever actually does.

    Don't be in a rush. And, for your own sake, don't try to skip the basics.

    Heh, don't mind us: we tend to get pedantic about semantics. ;)

    Learning is good. I want you to know two things: never use the center tag and you almost never need the br tag. As an addendum, sites like this can help a lot:

    As an example, for your markup, you could do something like:
    <!DOCTYPE html>
      <style type="text/css">
        #content {
          margin-top: 4em;
          text-align: center;
    <div id="content">
        <dt>Select your shipment amount of <b>COPPER</b></dt>
          <input type="range" min="0" max="200" value="0" onchange="copperValue(this.value)" />
          <div id="copperRange">0</div>
          <div id="copperTotal">0</div>
        <dt>Select your shipment amount of <b>SILVER</b></dt>
          <input type="range" min="0" max="5" value="0" onchange="silverValue(this.value)" />
          <div id="silverRange">0</div>
          <div id="silverTotal">0</div>
        <dt>Select your shipment amount of <b>GOLD</b></dt>
          <input type="range" min="0" max="4" value="0" onchange="goldValue(this.value)" />
          <div id="goldRange">0</div><br>
          <div id="goldTotal">0</div>
        <dd><div id="newTotal">0</div></dd>
    <script type="text/javascript">

    Here, we've gotten rid of those br tags, maintained the center you wanted, an allowed for all kinds of styling fun. It's generally considered good form to template in plain ole html as much as possible. Part of the reasoning is that if your javascript should crash, the user at least sees something.

    However, if your page requires javascript to even make sense, you might consider going all in. Here I use the excessively popular library jQuery and draw nearly the entire page in code.
    <!DOCTYPE html>
      <script src=""></script>
      <style type="text/css">
        #content {
          margin-top: 4em;
          text-align: center;
    <div id="content"></div>
    <script type="text/javascript">
    var Data = [
      { name: 'Copper', rangeMin: 0, rangeMax: 200, calc: function(x) { return x * (66.20 / 160 * 1.2); } },
      { name: 'Silver', rangeMin: 0, rangeMax: 5, calc: function(x) { return x * (16.36 * 1.2); } },
      { name: 'Gold', rangeMin: 0, rangeMax: 4, calc: function(x) { return x * (38.99 * 1.2); } }
    $(function () {
        var table = $("<table border='1'>").appendTo("#content");
        var tbody = $("<tbody>").appendTo(table);
        $.each(Data, function(i, x) { initData(x, $("<tr>").appendTo(tbody)); });
        var grandTotalDiv = $("<div>").appendTo("<td>").appendTo($("<tr><td colspan='3'>Grand Total</td>").appendTo(tbody));
        $.each(Data, function(i, x) { x.updateValues(); });
        function initData(data, tr) {
          data.value = 0;
          data.eleRange = 
            $('<input type="range" min="' + data.rangeMin + '" max="' + data.rangeMax + '" value="' + data.value + '">')
          data.unitDiv = $('<div>').appendTo($("<td>").appendTo(tr));
          data.totDiv = $('<div>').appendTo($("<td>").appendTo(tr));
          data.updateValues = function() {
            data.value = data.eleRange.val();
   = data.calc(data.value);
        function updateTotal() {
          var tot = 0;
          $.each(Data, function(i, x) { tot +=; });

    Keep learning and if you don't follow something here, don't sweat it; you will. Maybe this context will inspire you to go learn something new now. Have fun.

    The following list describes syntax rules for the the HTML syntax. Rules for the the XML syntax are defined in the XML specification.

    Sorry, if an XML parser coughs up blood on my HTML I consider it less than useful. However, you are correct, in some HTML specs you can be non conformant to XML. I don't know why you would wish to be, but you can.

    However, as br is mostly a non semantic crutch, you'll find few modern sources that will defend it's use over proper CSS.

    Ideally, you'd store the value you calculate rather than just loose it to text in the html. You could store it as you set it and get rid of that awful innerHTML repetition.

    I'm just going to throw this out there. Please read carefully and feel free to ask questions.
    <!DOCTYPE html>
    <script type="text/javascript">
    // normally you'd want the script element at the end, 
    // but it shouldn't hurt anything here
    // an object to hold values, initial values set
    var Values = { copperRange: 0.0, silverRange: 0.0, goldRange: 0.0 };
    // set value for both doc elements and our object
    // this allows us to look up values without worrying about DOM stuff
    function setValue(id, value) {
      var e = document.getElementById(id);
      // we can store values that don't actually map to DOM, if we like
      if (e) { e.innerHTML = value; } 
      Values[id] = value;
    // when we set a value via this, we also want to update several other values, so make the call
    function updateValue(id, value) {
      setValue(id, value);
    function onUpdateValue() {
      // do the math
      setValue("copperTotal", Values.copperRange * (66.20/160*1.2));
      setValue("silverTotal", Values.silverRange * (16.36*1.2));
      setValue("goldTotal", Values.goldRange * (38.99*1.2));
      setValue("newTotal", Values.copperTotal + Values.silverTotal + Values.goldTotal);
    // the functions our form calls
    function copperValue(value) { updateValue("copperRange", value); }
    function silverValue(value) { updateValue("silverRange", value); }
    function goldValue(value) { updateValue("goldRange", value); }
    // on the initial load, just set all the zeros
    <center><!-- this tag has been deprecated since 1999 -->
      <!-- a br tag, particularly one not closed, should raise all kinds of red flags -->
      <br><br><br><br><!-- Seriously time to learn CSS -->
      <p> Select your shipment amount of <b>COPPER</b></p>
      <input type="range" min="0" max="200" value="0" onchange="copperValue(this.value)" />

      <span id="goldTotal">0</span>
      <h3> Total </h3>
      <span id="newTotal">0</span>

    Hope this helps.
  5. In Topic: Stupid Spacing

    Posted 3 Jul 2015

    Ok, I do see a major bug in your writeFile:
    void writeFile(char file[], char output[][3], char newfile[])
       ofstream fout(newfile);
       for (int row = 0; row < 3; row++)
          for (int col = 0; col < 3; col++)
             fout << output[row][col];
          fout << endl;
          // you've only written one row
          // don't close now
       cout << "File written\n";

    You have too many magic numbers floating around in here. Particularly the "." to " " transformation. Define your const. Your save and load file is essentially a single string. e.g.
    #include <iostream>
    #include <fstream>
    const int ROWS = 3;
    const int COLS = 3;
    const char C_X = 'X';
    const char C_O = 'O';
    const char C_EMPTY = '.';
    typedef char Board[ROWS][COLS];
    void display(Board);
    bool writeFile(std::ostream &, Board);
    bool writeFile(const char *filename, Board);
    bool readFile(std::istream &, Board);
    bool readFile(const char *filename, Board);
    bool writeFile(const char *filename, const std::string &);
    using namespace std;
    int main() {
        const char *fn1 = "ttt1.txt";
        const char *fn2 = "ttt2.txt";
        // make a test file
        // note the helper function
        writeFile(fn1, "XO.....X.");
        Board b;
        if (!readFile(fn1, B)/>) {
            cout << "couldn't read " << fn1 << endl;
            return 1;
        cout << "writing: "; writeFile(cout, B)/>; cout << "." << endl;
        if (!writeFile(fn2, B)/>) {
            cout << "couldn't write " << fn2 << endl;
            return 1;
        Board b2;
        if (!readFile(fn2, b2)) {
            cout << "couldn't read " << fn2 << endl;
            return 1;
        return 0;
    void display(Board B)/> {
        for (int row = 0; row < ROWS; row++) {
            for (int col = 0; col < COLS; col++) {
                char c = b[row][col];
                cout << " " << (c==C_EMPTY?' ':c);
                if (col < COLS-1) { cout << " |"; }
            cout << " " << endl;
            if (row < ROWS-1) { cout << "---+---+---"; }
            cout << endl;

     X | O |   
       |   |   
       | X |   
    writing: XO.....X.
     X | O |   
       |   |   
       | X |   

    Note, as long as you test for your non magic chars, you should be able to verify your read. e.g.
    bool readFile(istream &in, Board B)/> {
        char c; // to read a single char into
        int size = ROWS * COLS;
        int count = 0;
        // your code here
            if (c==C_X || c==C_O || c==C_EMPTY) {
        // your code here
        return count==size;

    Hope this helps.
