Lotto Simulation Problem

ckw77 (11)
I think I got pretty much of the code, but I need help on the bottom. How do i define user and lottery.. Confused!! Also code is confusing so help also...

//Declarations
#include <iostream>
#include <cstdlib>
#include <ctime>

const int lotteryDigits = 10;
const int SIZE = 5;
const int Power = 1;

int generateLottery(int[], int, int);
int powerBall(int[], int);
int userInput(int[], int);
int count1= 0;
int matchCounter(int[], int[], int);
void displayNumbers(int[], int[]);
void displayhotball (int[], int[]);
void winnerOrLoser(int);
bool matches = true;



using namespace std;

int main()
{
int lottery[5] = {0, 0, 0, 0, 0};
int user[5] = {0, 0, 0, 0, 0};
int ball[1] = {0};
int matches = 0;

generateLottery(lottery, SIZE, lotteryDigits);

userInput(user, SIZE);

matchCounter(lottery, user, matches);

displayNumbers(lottery, user);

displayhotball(ball, user);

winnerOrLoser(matches);

system ("pause");
return 0;
}
//Randomly generates winning lottery numbers and power numer

int generateLottery(int lottery[], int, int)
{
unsigned seed = time(0);
srand(seed);

for (int y=0; y<SIZE; y++)
{
lottery[y] = rand() % lotteryDigits;
}

return lottery[0], lottery[1], lottery[2], lottery[3], lottery[4];
}

int powerBall(int ball[], int)
{
unsigned seed = time(0);
srand(seed);

int x;
for (x=0; x<Power; x++);
{
ball[x]= rand() % SIZE;
}

return ball[0];
}
//Reads user lottery number choices

int userInput(int user[], int)
{
for (int count1=0; count1<SIZE; count1++)
{

cout<<"Enter a digit between 0 and 9:--->";
cin>> user[count1];

while (user[count1]<0 || user[count1]>9)
{
cout<<" Error! Entry must be between 0 and 9--->";
cin>> user[count1];
}
}

for( int count1=0; count1<Power; count1++)
{
cout<<"Enter a hot power number between 0 and 5--->";
cin>> user[count1];

while (user[count1]<0 || user[count1]>5)
{
cout<<" Error! Entry must be between 0 and 5--->";
cin>> user[count1];
}
}
return 0;
}// end userInput

// Counts the number of matches

int matchCounter(int lotto [], int input[], int)
{
int match = 0;

for (int x = 0; x < SIZE; ++x)
{
if (lotto[x] == input[x])
match = match + 1;
}

return match;
}


//Displays the winning numbers and the user's number

void displayNumbers(int lottery[], int user[])
{
cout << "\nThe winning lottery numbers are: " << lottery[0] <<" "<< lottery[1]<<" "<< lottery[2]<<" "<<lottery[3]<<" "<<lottery[4]<< endl;
cout << "Your lottery numbers are: " << user[0] << " " << user[1] << " " << user[2] << " " << user[3] << " " << user[4] << endl;
}
//Displays Power Number
void displayhotball(int ball[], int user[])
{
cout << "\nHot Winning Number:" << ball[0]<< endl;
cout<< "Your hot number is:" << user[0]<< endl;
}

//Determines matches
void winnerOrLoser(int matches)
{
for (matches = 0; matches < SIZE; matches++)
{
while (matches < SIZE)
{
if (user[count1] != lottery[count1])
matches = false;
count1++;
}
cout << "You matched " << matches << " numbers";

if (matches != SIZE)
cout << "\nSorry--you lose. Better luck next time.\n";
else if (matches == Power)
cout << "\nCongratulations--you win $4!!!!\n";
else if (matches== 1&&Power)
cout<<"\nYou win $4\n";
else if (matches == 2)
cout<<"\nYou win $7\n";
else if (matches == 2&&Power)

What are code tags?

They're formatting tags so your code highlights syntax correctly. When you post, you can use the <> button in the formatting box on the right.

I guess a better answer is this...

The difference between getting your problem solved or not.
ckw77 (11)
Still not understanding, but I used the formatting key to edit the code above and that what I got. Can somebody just try running the code, and telling me what erroes I need to fix to get the program to run correctly.

First, Use code tags and indent.

//Determines matches
void winnerOrLoser(int matches)
{
    for (matches = 0; matches < SIZE; matches++)
    {
        while (matches < SIZE) //matches never changes in this loop.
        {
            //error: 'user' was not declared in this scope
            //error: 'lottery' was not declared in this scope
            if (user[count1] != lottery[count1])
                matches = false;
            count1++;
        }
        cout << "You matched " << matches << " numbers";

        if (matches != SIZE)
            cout << "\nSorry--you lose. Better luck next time.\n";
        else if (matches == Power)
            cout << "\nCongratulations--you win $4!!!!\n";
        else if (matches== 1&&Power)
            cout<<"\nYou win $4\n";
        else if (matches == 2)
            cout<<"\nYou win $7\n";
        else if (matches == 2&&Power)
            cout<<"\nYou win $7\n";
        else if (matches == 3)
            cout<<"\nYou win $7\n";
        else if (matches == 3&&Power)
            cout<<"\nYou win $100\n";
        else if (matches == 4)
            cout<<"\nYou win $100\n";
        else if (matches == 4&&Power)
            cout<<"\nYou win $10000\n";
        else if (matches == 5)
            cout<<"\nYou win $100000\n";
        else ( matches == SIZE);
            cout<< "\nYou win $2,000,000\n";
    }
    //error: expected '}' at end of input


To fix the user and lottery problem, add parameters to the function for user[] and lottery[]:

void winnerOrLoser(int matches, int user[], int lottery[])

(Remember to adjust your function prototype accordingly)

Finally, add a } at the end of your winnerOrLoser function, and it should work (my output, notice the "ctrl C" [^C] at the end, you have an infinite loop in your winnerOrLoser function):

Enter a digit between 0 and 9:--->1
Enter a digit between 0 and 9:--->2
Enter a digit between 0 and 9:--->3
Enter a digit between 0 and 9:--->4
Enter a digit between 0 and 9:--->5
Enter a hot power number between 0 and 5--->6
 Error! Entry must be between 0 and 5--->-1
 Error! Entry must be between 0 and 5--->5

The winning lottery numbers are: 7 7 8 3 9
Your lottery numbers are: 5 2 3 4 5

Hot Winning Number:0
Your hot number is:5
^C


Once you get that going, let us know as there are a few things (related to the design) that I noticed about your code that should be fixed.

Comment on mine?


*This is a vague response to a vague question.* Are you asking if I am commenting on your code or are you asking me to comment on your code?

Fixed another little bug:


What was the bug? Or do you expect us to read all 160 lines of each post and figure it out? *Tip* there's an edit button. Use it to edit your old posts and fix bugs instead of flooding the page (mah scroll wheel is begging of you). And make sure you make a mention of what you changed and why.

(Can't you press it down to engage fast scrolling?)

But no one notices editing...

Which is why you make a post at the same time saying: Previous code edited to fix: "Insert something here."

If you edit previous posts there's no history, so anyone coming late to the conversation can a) not tell what's already been fixed, and b) not learn anything from seeing how someone else fixed their problems.

I know it generates more bandwidth, but it is useful to see the evolution of a solution.

On the other hand if it is a simple bug fix, there isn't any evolution, there is only a minor correction, and correcting it in the original post is probably better than reposting umpteen lines of unchanged code and tempting people coming late to the thread to respond with a fix for said bug without reading the entire thread, thereby giving everyone a higher noise to signal ratio.

Just mentioning what the fix is solves both problems to some degree.

I guess it depends on the thread content.

I tend to refer to specific lines in the posted problem code, so any editing that goes on will render my comments confusing, at best, and probably useless. No witty remarks, thankyouverymuch ;-)

Uhhhh ok,

Previous code to fix = ADDED FUNKY COLORS!
