Question

This needs to be done using c++

No vectors or arrays can be used since we haven't learned them yet!

Write a program that simulates a slot machine. The slot machine should have the following characteristics:

- 3 view windows to display items on a wheel. Typically, these are cherries, bars, etc.

- each wheel will randomly select a number 1-7.

- the user will be charged 5 tokens to spin the wheels

Winning combinations will be as follows:

- JACKPOT will consist of 7, 7, 7. The user will win 500 tokens.

- TRIPLE will consist of any other combination (1-6) where all numbers match. The user will win 100 tokens.

- STRAIGHT will consist of any "in-order run". For example: 1, 2, 3 or 3, 4, 5… The user will win 50 tokens.

- DOUBLE will consist of any matching pair. For example: 1, 2, 1 or 3, 4, 4 … The user will win 3 tokens.

General algorithm: To start the game, the user will input a specific integer to initialize the random number generator. This is to allow the test cases to create duplicate output.

srand( randomInit ); // randomInit is an integer variable, input by the user

The user will then enter the number of tokens to begin. This will simulate banking/inserting money into the slot machine.

If the user has enough tokens, begin the game by subtracting the number of tokens to play the game from the users bank.

The slot machine will spin the wheels by generating 3 random numbers. Display the numbers.

Determine if the 3 random numbers are a winning combination. Display a message if the user wins or loses (see below). If the user wins, add the appropriate amount of tokens to the users bank.

If the user has enough tokens, they will be asked to play again (y/n). If the user has enough tokens and they want to play again, repeat the game. If the user does not have enough tokens to play, they should not be prompted to play again. An error message should be displayed: Sorry, you need 5 tokens to play. and the game ends.

Display a message at the end of the game to show it completed successfully. Thank you for playing. Come again.

Sample Input:

30000 100 y y y y n

Sample Output:

*5* *3* *3*

***************

* DOUBLE!! *

***************

You have 98 tokens.

*5* *1* *7*

***LOSER!!***

You have 93 tokens.

*2* *3* *4*

***************

* STRAIGHT!! *

***************

You have 138 tokens.

*1* *3* *5*

***LOSER!!***

You have 133 tokens.

*2* *6* *6*

***************

* DOUBLE!! *

***************

You have 131 tokens.

Thank you for playing. Come again.

#include<iostream>

using namespace std;

int main(){

// declaring constants and variables
int randomInit; //seed
int balance; //tokens
int charge = 5; //tokens charged per play
int x_min = 1,x_max = 7; // range of targets
int x1,x2,x3; // targets from different spins
char play='n'; // decision variable to play or not

// user input for seed of random generator
cout<<endl<<"Enter any integer: "; cin>>randomInit;
srand(randomInit);

// depositing tokens
cout<<endl<<"Enter number of tokens (minimum 5): "; cin>>balance;

do
{
balance = balance - charge;

// generating 3 random integers (targets) x1,x2,x3 between x_min and x_max
x1 = x_min + (rand() %7+1 / (x_max-x_min+1));
x2 = x_min + (rand() %7+1 / (x_max-x_min+1));
x3 = x_min + (rand() %7+1 / (x_max-x_min+1));

// displaying the targets scored
cout<<"*"<<x1<<"**"<<x2<<"**"<<x3<<"*"<<endl;

// determining the earnings according to target scores
if(x1==7 && x1==x2 && x2==x3){
cout<<"******JACKPOT!!!!!!*******"<<endl;
cout<<"*********************"<<endl;
balance = balance + 500;
}else if(x1==x2 && x2==x3){

balance = balance + 100;
}else if((x2-x1)==1 && (x3-x2)==1){

cout<<"*********************"<<endl;
balance = balance + 50;
}else if(x1==x2 || x1==x3 || x2==x3){
cout<<"******DOUBLE!*******"<<endl;
cout<<"*********************"<<endl;
balance = balance + 3;
}else{
cout<<"LOSER!"<<endl;
}

// displaying current token balance
cout<<"You have "<<balance<<" tokens"<<endl;

// deciding the continuity of the game after earnings and charges
if (balance>=charge){
cout<<endl<<"Play again? (y/n): ";cin>>play;
}else{
cout<<endl<<"Sorry, you need 5 tokens to play"<<endl;
play = 'n'; // terminate the loop
}
cout<<endl;
}while(play=='y');

cout<<"Thank you for playing. Come again"<<endl;

return 0;
