Slot machine help?

[whatisjeff]

I am making a program that emulates a slot machine. I have three functions, each of which represent one of the three reels. Each function vertically displays a three symbol sequence of the reel. How do I place each function side by side so that I get a 3 x 3 grid of the slot machine's values?

# include <ctime>
# include <cstdlib>
# include <iostream>
# include <iomanip>

using namespace std;

//Value between 1-20, random
// Each value represents a three symbol sequence on a reel
int LeftReel ()
{
    return rand() % 21;
}

void LeftReelSymbol()
{
    switch (LeftReel())
    {
    case 1:
        cout << "Bell " << '\n' << '\n' << "Orange " << '\n' << '\n' << "Blueberry "<< '\n';
        break;
    case 2:
        cout << "Orange " << '\n' << '\n' << "Blueberry " << '\n' << '\n' << "Bell "<< '\n';
        break;
    case 3:
        cout << "Blueberry " << '\n' << '\n' << "Bell " << '\n' << '\n' << "Orange "<< '\n';
        break;
    case 4:
        cout << "Bell " << '\n' << '\n' << "Orange " << '\n' << '\n' << "Lemon "<< '\n';
        break;
    case 5:
        //Continues like this for all values between 1-20

    }
}

int MiddleReel ()
{
    return rand() % 21;

}

void MiddleReelSymbol()
{
    //Same as LeftReelSymbol(), but different sequences
}


int RightReel ()
{
    return rand() % 21;
}

void RightReelSymbol()
{
    //Same as LeftReelSymbol(), but different sequences
}

int main()
{

    srand(time(NULL));

    cout << "Slot machine!" << '\n' << '\n';
//Here in the program, all of the functions display their outputs
//But instead of being lined up like a typical slot machine, 
//It just ends up looking a list
    LeftReelSymbol();
    MiddleReelSymbol();
    RightReelSymbol();


}
}

You have two options.

1) Put all the output into a string buffer and print the buffer all at the same time.

2) Use a console control program to allow you to define sub-windows in the console window and/or position the cursor in the window and write stuff there.

It looks like all you really need to do, though, is adjust your print width with something like:

    const char* symbol[] = { "Apple", "Banana", "Orange", "Bar", etc };

    int left_reel = LeftReel();
    int middle_reel = MiddleReel();
    int right_reel = RightReel();

    for (int n = -1; n < 2; n++)
    {
        cout << setw( 26 ) << left << Symbol[ left_reel   + n ] << flush;
        cout << setw( 26 ) << left << Symbol[ middle_reel + n ] << flush;
        cout << setw( 26 ) << left << Symbol[ right_reel  + n ] << endl;
    }

Hope this helps.

So I did this:

cout << setw( 26 ) << left << LeftReelSymbol() << endl;

And this error popped up:

"no match for 'operator<<' in '(& std::operator<< <char, std::char_traits<char> ..."

Sorry, this setw thing is something I haven't learned about yet

[devildeuces]

to use setw(#) you need to include the library #include <iomanip>

[whatisjeff]

Yes, I did that. These are all the things at the top of my program:

# include <ctime>
# include <cstdlib>
# include <iostream>
# include <iomanip>

using namespace std;

[Duthomhas]

LeftReelSymbol() doesn't return anything; it is a void function.

[edit]And you can't print something that doesn't exist.

[giblit]

You should put the setw in the leftreelsymbol function or have the function return a string of what you want to output.

[whatisjeff]

I got setw to work, but all it does is indent the the left reel. The other reels still don't line up.
