Have a few questions about C++

[Cbick]

Hello all,
I am fairly new to C++ and am having a problem with one of my assignments.
It involves making a slot machine that generates random numbers. One of the problems that I am having is the random numbers do not generate my out put always comes up as [0][0][0] so it always hits jackpot. Another concern I have is that I think that I need to uses a case structure where the payout is calculated but not sure how to do that. Here is my code

#include <iostream>
#include <ctime> 

using namespace std; 

class slotMachine {
private:
int wheelA;
int wheelB;
int wheelC;
double payOut; //amount of $ won during the current turn
double moneyInMachine; //total amount of $ in the machine
double playersBalance; //the amount of $ not yet played
double gameCost; //the cost of one pull
double moneyPaid; //the money put in by user
public:
slotMachine();
bool displayMenu(void);
bool pullHandle(void);
void spinWheel(int &);
double calculatePayout();
void insertCoin(double );
void displaySpinResults();
int Random(int, int);
void displayTotals();
}; 

int main(void) {
//create a slot machine object 
slotMachine mySlot; 

//Start the slot machine game
//Keep running until the user
//decides to quit 

bool ok = true;
while (ok){
ok = mySlot.displayMenu();
}; 

return 0; 
} 

slotMachine::slotMachine () {
//constructor, set the initial state
//of all the properties 

srand((int) time(0));
moneyInMachine = 100;
moneyPaid = 0;
payOut = 0;
wheelA = 0;
wheelB = 0;
wheelC = 0;
gameCost = 1;
} 

bool slotMachine::displayMenu(void){
//main menu, executes the command selected by the
//user or returns a value to terminate game execution

char choice = 'Z'; 

bool continueGame = true; 

cout << "\n\n(E)nd, (P)ull, P(A)Y, (T)otals :"; 
cin >> choice; 

switch (choice) {
case 'e':
case 'E': //stop game 
continueGame = false; 
break; 
case 'a':
case 'A': //pay 
double money; 
cout << "\nIt's a dollar a pull!\n" 
<< "Put money into the machine $"; 
cin >> money; 
insertCoin(money); 
break; 
case 'p':
case 'P': //pull 
if (pullHandle()){ 
cout << endl << endl << endl; 
displaySpinResults(); 
cout << "Payout $" << calculatePayout(); 
} 
break;
case 't':
case 'T': //display totals 
displayTotals();
break;
}
return continueGame; 
} 

bool slotMachine::pullHandle(void){
//checks to see if there is enough user money 
//for a spin. If so, assigns a random value
//to each wheel. Deducts the cost of one
//pull from the users money. 
//returns true if the handle was pulled.
//returns false if the handle could not be pulled 
double moneyInMachine = 25;
int wheelA = 1;
int wheelB = 2;
int wheelC = 3;

 playersBalance = moneyInMachine - moneyPaid;
 cout << "You have " << playersBalance << endl;

return true;

} 

void slotMachine::spinWheel(int &theWheel){
//assign a random value to a wheel 
int wheelA = rand();
int wheelB = rand();
int wheelC = rand();
}
int rand();
{
int wheelA;
wheelA = 1 + rand() % (3 - 1 + 1 );
int wheelB;
wheelB = 1 + rand() % (3 - 1 + 1);
int wheelC;
wheelC = 1 + rand() % (3 - 1 + 1);
}

double slotMachine::calculatePayout(){
//decides if the current wheel values merit a 
//payout and how much that payout should be.
//deducts the total payout from the total
//amount of money in the machine
int jackPot = 1000;
int goodJob = 10;
int youLose = 5;
int wheelA = rand();
int wheelB = rand();
int wheelC = rand();

if (wheelA == wheelB && wheelA == wheelC)
{
	playersBalance = moneyInMachine + jackPot;
	cout << "Jackpot!!!  " << jackPot << endl;
	
}
 else if (wheelA == wheelB != wheelC || wheelA == wheelC != wheelB || wheelB == wheelC != wheelA)
{
	playersBalance = moneyInMachine + goodJob;
	cout << "Good Job  " << goodJob  << endl;
	
}

 else (wheelA != wheelB != wheelC || wheelA != wheelC != wheelB || wheelB != wheelC != wheelA);
{
	playersBalance = moneyInMachine - youLose;
	cout << "You Lose,Play Again" << endl;
	cout << " You have    " << playersBalance << endl;
	
}
return moneyInMachine;


} 

void slotMachine::insertCoin(double amount = 0){
//adds to the amount of money paid by the user
//adds to the total money in the machine
int moneyInMachine = 25;
int moneyPaid = 0;

moneyInMachine = moneyPaid + moneyInMachine;

} 

void slotMachine::displaySpinResults(){
//displays the value of the three wheels
cout << "[" << wheelA << "] " 
<< "[" << wheelB << "] " 
<< "[" << wheelC << "] \n\n" ; 
} 

void slotMachine::displayTotals(){
//displays the amount of money and number
// of pulls the player has left
cout << "\nMoney in Machine $" << slotMachine::moneyInMachine << endl;
cout << "Pulls Left: " << slotMachine::gameCost / slotMachine::moneyPaid << endl << endl; 
} 

int slotMachine::Random(int lowerLimit, int upperLimit) {
//returns a random number within the given boundary
 return 1 + rand() % (upperLimit - lowerLimit + 1); 
}

Please remove that code, type "[code]", paste your code in, and then type "[/code]". It keeps your original formatting. So this:
#include <iostream>

int main() {
std::cout << "Hello, world!" << std::endl;
std::cin.get();
return 0;
}

becomes this:

#include <iostream>

int main() {
    std::cout << "Hello, world!" << std::endl;
    std::cin.get();
    return 0;
}

You could use this random number generator. It's fairly simple yet very effective:

    int randNum = 0, min = 0, max = 9, range = (max - min) + 1;
    randNum= min + int(range * rand() / RAND_MAX + 1.0));

Try seeding rand like this:

srand((unsigned)time(0)); 

and put your seed statement below your #includes aswell.

I got that code from here: http://www.daniweb.com/forums/thread1769.html
a while ago, and I've been using it ever since. It's very good. Just change the value of min and max. Obviously don't just copy and paste it; rewrite it and try to understand it...

ok I have redid my code and also made a few changes to it but still having trouble with generating the random numbers

[chrisname]

Try the above random number generator.

Add some cout statements so you can see what happens at each point.

[Cbick]

Yes that would work but there are some things in the code that I cannot change because it was code given for my assignment.

#include <ctime> 
srand((int) time(0));

and doubt I can change those as it would result in not doing my assignment right.

Alternative way to use rand that doesn't involve converting to and from floating point:

int min = 0, max = 10;
int range = max-min;

int randNum = (rand() % range) + min;

Note this returns a number between [min..max). IE, max is exclusive, so with the above you'd get 9, but never 10.

I give up I cannot make this code run the way it is supppose to. Been working on this since 10 am yesterday and haven't really gotten much farther than waht I was then. Thanks everyone whom replied for your help.
