Question

This is a Slot Machine Simulation and I keep getting an error at the end of the main module. (//pause system system("Pause"); return 0; }//end main() this is the section that keeps giving me an error. Please help my code is below.

#include<cstdlib>
#include<iostream>
#include<string>
#include<cmath>
#include<iomanip>

//declare variables
int spin(int);
void playGame();
float insertMoney(float);

int showSpin(int, int, int);
int showSymbol(int);
int getMatches(int, int, int);
float calcWinnings(int, float);
char wantToPlayAgain(char);

using namespace std;
// Global constants to represent the slot machine symbols
const int CHERRIES = 1;
const int ORANGES = 2;
const int PLUMS = 3;
const int BELLS = 4;
const int MELONS = 5;
const int BARS = 6;

int main()
{
// The again variable is used to determine whether the
// user wants to continue playing the game.
char again;
float money;

// Start playing?
do
{
// Pressing a key spins the machine.
cout << "Press Enter to spin? " << endl;
cin.get();

// Simulate the spin.
playGame();

// Does the user want to play again?
while (wantToPlayAgain(again) == 'Y');
}//end do

//pause system
system("Pause");
return 0;
}//end main()

// The playGame module plays one spin of the slot machine.
void playGame()

//declaration of variables
int symbol1, symbol2, symbol3, matches;
float money, winnings;

//insert the money

// Get the number of matching symbols.

// Get the game winnings.

// Display the winnings.

}//end module(playGame)

//insertMoney module
float insertMoney(float money)

//spin module

}//end module(switch)

}//end module(showSymbol)

// The getMatches function accepts arguments for the three

{

// Do all three symbols match?
if (symbol1 == symbol2 && symbol1 == symbol3)

// the amount of money inserted as arguments, and returns the
// amount of money won for this spin.
float calcWinnings(int matches, float money)
{

}//end float(calcWinnings)

// The wantToPlayAgain module asks the user if he or she wants to
// play again and stores the input as "Y" or "N" in the reference
// parameter.
char wantToPlayAgain(char again)
{
// Ask the user?

// Validate the input.
while (again != 'Y' && again != 'N')

cout << "Enter either Y or N. ";
cin >> again;
}//end while
}//end module(wantToPlayAgain)

Explanation / Answer

Checked above program and found that do-while() loop is used for looping and while is written before close braces "}"

corrected while loop and executed, program executed successfully .

I am not sure about the functionality of the program but it is compiled and executed.

do
{
// Pressing a key spins the machine.
cout << "Press Enter to spin? " << endl;
cin.get();

// Simulate the spin.
playGame();

// Does the user want to play again?
}while (wantToPlayAgain(again) == 'Y');

Could you please use above block of logic in main, compile & execute

do
{
// Pressing a key spins the machine.
cout << "Press Enter to spin? " << endl;
cin.get();

// Simulate the spin.
playGame();

// Does the user want to play again?
}while (wantToPlayAgain(again) == 'Y');
