Question

(C++) Why does my code not continue looping? it only loops twice. Can someone take a look at my code so far:

#include <iostream>

#include <cmath>

#include <cstdlib>

#include <string>

#include <ctime>

using namespace std;

void cls(void);

void cls(void) {

system("cls||clear");

return;

}

int main() {

int BankBalance = 0;

char quit;

int wager = 0;

int inputWager = 0;

int sum = 0;

int diceRoll = 0;

int rollPoint = 0;

int point = 0;

int dice1 = 0;

int dice2 = 0;

char playerResponse;

srand(time(0));

cout << "Hey there buddy. Welcome to the game of Craps!!! Glad you can make it :D\n\n";

cout << "Let's start with the boring rules:\n\n ";

cout << "A player rolls two dice. each die has six faces." << endl;

cout << "These faces contain 1, 2, 3, 4, 5, and 6 spots. After the dice have come to rest, the sum of the spots on the two upward faces is calculated." << endl;

cout << "If the sum is 7 or 11 on the first throw, the player wins. if the sum is 2, 3, or 12 on the first throw (called 'craps'), the player loses (i.e. the 'house' wins)." << endl;

cout << "If the sum is 4, 5, 6, 8, 9, or 10 on the first throw, then the sum becomes the player's 'point'." << endl;

cout << "To win, you must continue rolling the dice until you 'make your point'. The player loses by rolling a 7 before making the point.\n\n";

cout << "Please enter your initial Bank Balance: $";

cin >> BankBalance;

while (cin.fail()) {

cin.clear();

cin.ignore(256, '\n');

cout << "Invalid input detected, please enter a valid amount: $";

cin >> BankBalance;

}

cout << "\nCurrent bank balance: $" << BankBalance << endl;

cout << "Total wager so far: $" << wager << endl;

cout << "Please enter your wager: $";

}

}

}

else if (sum == point) {

cout << "\nBank Balance: $" << BankBalance << endl;

}

dice1 = rand() % 6 + 1;

dice2 = rand() % 6 + 1;

sum = dice1 + dice2;

cout << "Sum: " << sum << " (Die 1: " << dice1 << " Die 2: " << dice2 << ")" << endl;

cout << "\n\nCurrent bank balance: $" << BankBalance << endl;

}

else {

cout << "\nYou need to roll to make your point (" << sum << ")..." << endl;

//system("pause");

//point = sum;

//rollPoint(point, wager);

}

return 0;

}

Answer 1

// USE GOTO STATEMENT TO ROLL AGAIN

// OR USE WHILE LOOP TO ASK WHETHER U WANT TO ROLL AGAIN OR NOT
