Completing function for dice game

spitzlara (3)
Need help completing the methods for the functions of getBet and wonTheBet.

Please help asap!




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


int main ()
{
srand(time(NULL));
int money = 100, bet;

while (money > 0) {

cout << "You currently have " << money << " dollars. \n";
bet = getBet(money);

if (wonTheBet()) {
int amount = bet * 2;
money += amount;
cout << "Congratulations! You just won " << amount << " dollars!\n\n";
}

else {
money -= bet;
cout << "Ah, you lost! Try again! \n\n";
}

}

cout << "You are out of money!\n";
return 0;
}


THANK YOU!

I'd say that in the function void getBet() you have to let the user type in an amount they want to bet (you can do this using cin) and thus set the variable int bet . You also need to let the user choose which side of the dice they want to bet on, which would be another variable.
The if-statement you have there at the moment doesn't make any sense, as you can do all this in the function void wonTheBet(). At the moment you also need to actually "roll the dice" and compare the value of the randomly chosen side to the one the user has his bet on. If its the same, call the function wonTheBet, if not call a function lostTheBet, which has the logic of your current else-statement.

I hope this helped you, if there are any more questions, feel free to ask ;).

Can you show me how you would write this out?
I need to complete it for homework...
Thanks

Here you go, but it's really likely that not everyone will paste completed code for you, so consider yourself lucky ;)
