    This guy is thinking about quitting programming for good --------------------->

    Ok I've been analyzing the same code for like one week now and I am starting to think that I am not made this stuff or maybe the book is just bad..............................
    PS this is not the whole code.

    String::String()
    {
    itsString = new char[1];
    itsString[0] = '\0';
    itsLen=0;
    }

    Ok, can you tell me that this does?

    This is an "implementation" statement...
    prior to this there was a "string" class declared.

    This a implementation of a "user-defined" constructor.
    ------- I hope that you know "classes"...???

    Every time you declare an object of the "string" class this constructor is called, and whatever is in the body of this constructor gets executed...

    which is...::::

    {
    itsString = new char[1]; // means that a compilers reserved an array of 2 characters of the "free store" (or heap); and assigned that empty space to the member variable "itsString"

    .... ---- Hope you know Pointers and little bit about "dynamic memory allocation".....???


    next...

    itsString[0] = "\0"; // this means....assign "NULL" to the first member of an array, in this case "itsString" with a substring [0]...

    ----- this array contains two (2) members declaration array[1]... is array[0] and array[1];

    the last one....

    itsLen = 0; // in this case ...assigns 0 to (most likely) private data member "itsLen", which "itsLen" is probably an integer....

    that's all it is....

    i am sure there's a lot more in that whole program but this should answer your questioon....as long as i didn't confuse you any more.

    good luck
