Slot Game

I've developed a slot machine game. It is perfect now except for 1 thing, the random numbers don't change. Have you got any advice?

Code:

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

int main()
{
    srand(time(0));
    int num1=rand()%10+1;
        srand(time(0));
    int num2=rand()%10+1;
        srand(time(0));
    int num3=rand()%10+1;
    int coins=10;
    cout<<"---------------------------------------------------------------------"<<endl;
    cout<<"                 Welcome to slot machine"<<endl;
    cout<<"                    You have 10 coins"<<endl;
    cout<<"      If all 3 numbers that appear are the same, you get 10 coins"<<endl;
    cout<<"          If 2 numbers are the same, you get 3 coins"<<endl;
    cout<<"          If all 3 numbers are different, you lose 1 coin"<<endl;
    cout<<"                     Hit enter to play"<<endl;
    cout<<"---------------------------------------------------------------------"<<endl;cin.get();
    cout<<""<<endl;
    while(coins<100)
    {
    cout<<num1<<"     "<<num2<<"     "<<num3<<"     "<<endl;
    if(coins<1)
    {
        coins=coins+10;
        cout<<"You are bankrupt, your money is reset. You now have "<<coins<<endl;
        cout<<"coins"<<endl;
    }    
    else if(num1==num2&&num1==num3)
    {
        coins=coins+10;
        cout<<"You got the jackpot. You now have "<<coins<<" coins"<<endl;cin.get();
    }    
    else if(num1==num3||num1==num2||num2==num3)
    {
        coins=coins+3;
        cout<<"You won 3 coins. You now have "<<coins<<" coins"<<endl;cin.get();
    }
    else
    {
        coins=coins-1;
        cout<<"You lose 1 coin. You now have "<<coins<<" coins"<<endl;
    }
}
cout<<"You have won the game. Congratulations.";cin.get();
return 0;
}

call srand only once in the program. And in that whole whileloop you have there you never change the values of num1, num2 or num3.

I've edited it so that srand is called only once and the rand calls are placed inside the loop.

Code:

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

int main()
{
    int num1;
    int num2;
    int num3;
    int coins=10;
    srand(time(0));
    cout<<"---------------------------------------------------------------------"<<endl;
    cout<<"                 Welcome to slot machine"<<endl;
    cout<<"                    You have 10 coins"<<endl;
    cout<<"      If all 3 numbers that appear are the same, you get 10 coins"<<endl;
    cout<<"          If 2 numbers are the same, you get 3 coins"<<endl;
    cout<<"          If all 3 numbers are different, you lose 1 coin"<<endl;
    cout<<"                     Hit enter to play"<<endl;
    cout<<"---------------------------------------------------------------------"<<endl;cin.get();
    cout<<""<<endl;
    while(coins<100)
    {
    num1=rand()%10+1;
    num2=rand()%10+1;
    num3=rand()%10+1;
    cout<<num1<<"     "<<num2<<"     "<<num3<<"     "<<endl;
    if(coins<1)
    {
        coins=coins+10;
        cout<<"You are bankrupt, your money is reset. You now have "<<coins<<endl;
        cout<<"coins"<<endl;
    }    
    else if(num1==num2&&num1==num3)
    {
        coins=coins+10;
        cout<<"You got the jackpot. You now have "<<coins<<" coins"<<endl;cin.get();
    }    
    else if(num1==num3||num1==num2||num2==num3)
    {
        coins=coins+3;
        cout<<"You won 3 coins. You now have "<<coins<<" coins"<<endl;cin.get();
    }
    else
    {
        coins=coins-1;
        cout<<"You lose 1 coin. You now have "<<coins<<" coins"<<endl;
    }
}
cout<<"You have won the game. Congratulations.";cin.get();
return 0;
}

you guys are brilliant

You still have one problem: If I have one coin, I insert it, I get results, but they are never evaluated. It tells me that I'm bankrupt and resets my coins, then another round is started.

good point, ill get on it right away

fixed

Code:

#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;

int main()
{
    int num1;
    int num2;
    int num3;
    int coins=10;
    srand(time(0));
    cout<<"|------------------------------------------------------------------------------|"<<endl;
    cout<<"|                           Welcome to slot machine                            |"<<endl;                    
    cout<<"|                                By Paul Leone                                 |"<<endl;
    cout<<"|                              You have 10 coins                               |"<<endl;

    while(coins<100)

    if(coins<1)
    {
        if(num1!=num2&&num1!=num3&&num2!=num3)
        {
            coins=coins+10;
        cout<<"You are bankrupt, your money is reset. You now have "<<coins<<endl;
        cout<<"coins"<<endl;cin.get();cin.get();
    }    
        else if(num1==num2&&num1==num3)
        {
                coins=coins+10;
        cout<<"You got the jackpot. You now have "<<coins<<" coins"<<endl;cin.get();cin.get();
    }
    else if(num1==num2||num1==num3||num2==num3)

    }
}
cout<<"You have won the game. Congratulations.";cin.get();
return 0;
}

Unnecessary code duplication. It should be more like (in pseudo-code):

Code:

main()
{
  init and welcome;

  do {
    generate and display random numbers;

    if(jackpot) {
      jackpot message;
      coins += 10;
    } else if(minor win) {
      minor win message;
      coins += 3;
    } else {
      loss message;
      coins -= 1;

      if(coins <= 0) {
        bankrupt message;
        reset coins;
      }
    }

  } while(coins < 100);
}

fair enough but i can't be arsed changing it, besides it doesn't matter because i decided to make it to see if i really understood the stuff i was learning. this proves that i do because i wasn't even learning random numbers
