    Dice Function..

    int getDice()

    I am trying to write a function to return the value of a thrown dice. the function will return the dice value, a number between 1 and 6.

    i know you use the srand and the rand and make the function output it but i don't really know how to write that.

    I will offer ye' one method:

    first.. create pair of dice:
    Code:
    struct PairOfDice
    {
         int dice_1;
         int dice_2;
    }


    let's prototype a dice roll function that will handle this new 'PairOfDice' data type..
    Code:
    PairOfDice* roll_the_dice(PairOfDice &DiceStruct) ;

    in your int main( ) function, declare an object of type PairOfDice:
    Code:
    PairOfDice *myDice ;

    then, when you are ready.. roll the dice..!
    Code:
    myDice = roll_the_dice(myDice) ;

    and now you have.. a pair o' dice
    Code:
    cout << "Roll 1 is:  "  <<  myDice->dice_1 ;
    cout << "Roll 2 is:  "  <<  myDice->dice_2 ;

    Now.. all you have to do is write up the function definition.. not too hard.. just randomly set the two attributes of the 'PairOfDice' object.

    OOP goodness

    what? you've never rolled 2 dice and got the same result on each die?

    besides that wasn't what the OP was asking at all.

    OP, I could tell you how to write a function which uses rand to return a value between 1 and 6, but I'd prefer you to try yourself first.

    Hint: you'll need to use the % modulo operator (aka the remainder operator).

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?
