How to write a function that checks combinations of 3 numbers? - c++

Question

I'm currently making a 2 player dice game and i need to create a function that checks the value of the dice combination you rolled. Ex: I rolled 3-4-2, I need the function to check if there is a payout for 3-4-2, example rolls and their payouts + code below
//Rolling 1-1-1 would give you 5x your wager
//Rolling 3 of the same number (except 1-1-1) would give you 2x wager
//Rolling 3 different numbers (ex 1-4-6) would give you 1x your wager
//Rolling 1-2-3 makes the player automatically lose a round and pay opposing Player 2x wager
#include <iostream>
#include <string>
#include <time.h>
using namespace std;
void roll_3_dice(int &dice1, int &dice2, int &dice3)
{
srand(time(NULL));
dice1 = rand() % 6 + 1;
dice2 = rand() % 6 + 1;
dice3 = rand() % 6 + 1;
return;
}
int main()
{
int cash = 90000;
int wager;
int r;
//dealer's die
int dealer1;
int dealer2;
int dealer3;
// your die
int mdice1;
int mdice2;
int mdice3;
while ( cash > 100 || round < 10 )
{
cout << "Set your wager: "<< endl;
cin >> wager;
while (wager < 100 || wager > 90000)
{
cout << "Minimum wager is 100; Maximum wager is 90000 ";
cin >> wager;
}
cout << "You wagered: " << wager << endl;
cout << "You have " << cash - wager << " remaining" << endl;
cash = cash - wager;
cout << endl;
cout << "Dealer will now roll the dice" << endl;
roll_3_dice(dealer1, dealer2, dealer3);
cout << "Dealer rolled the following: " << endl;
cout << dealer1 << "-" << dealer2 << "-" << dealer3 << endl;
cout << "It's your turn to roll the dice." << endl;
cout << endl;
cout << "Press any key to roll the dice" << endl;
cin >> r;
roll_3_dice(mdice1, mdice2, mdice3);
cout << "You rolled the following: " << endl;
cout << mdice1 << "-" << mdice2 << "-" << mdice3 << endl;
system ("pause`enter code here`");
}
}

Answer 1

I would suggest to write your algorithm on a paper first, like you did in the comments on top of the code.
Then, ask yourself what you need to process the final wager ? As in parameters. For instance, in your case, you may need a function which takes the initial wager, and the values of the three dices as entry parameters.
This function would return the final wager.
Finally, in the function itself, organize the algorithm by priority rules.
If 1-1-1 gives you 5x your wager, then it's a particular case which can be isolated at the top of the function maybe, and you can return 5 x initial wager directly, without any need to process further operations.
You'll just have to organize the different cases with if statements, regarding the priorities of each statement.
The 1-1-1 case has to come before the "same number for each dice" for example.
Hope this helps.
