How to fix this?

[mayuki4846]

The output is, the selection is keep appearing. Also, I already put system("CLS"); in the case 0 then goto receipt. Why the selection is keep appearing?

Also, while putting the another quantity, the selection is keep appearing.

i put "meow meow meow", because i was still testing it.

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

using namespace std;

int main()
{
		string customername, address, customertin;
        double lays = 1.1390, luxury = 1.9178, marshies = 0.2531;
        int choice, q1 = 0, q2 = 0, q3 = 0, q4 = 0, q5 = 0;
        double total, cash;


		cout << "Customer Name: ";
		getline(cin, customername);
	
		cout << "Customer Address: ";
		getline(cin, address);

	
		cout << "Customer TIN: ";
		getline(cin, customertin);

		
		system("CLS");

        while(true)
        {
        	
                cout << "Please make a selection" << endl << endl;
                cout << "Enter 1 for Lays Stax Sour Cream Onion 100g - $" << setprecision(4) << lays << endl;
                cout << "Enter 2 for Luxury Vegetable Chococream 200g - $" << luxury << endl;
                cout << "Enter 3 for Marshies Strawberry Style - $" << marshies << endl;
                cout << "Enter 4 to see what you owe" << endl;
                cout << "Enter 0 when you are done" << endl << endl;

                cout << "Choice: ";
                cin >> choice;
				cout << endl;
				



                switch(choice)
                {
                case 1:
                        cout << "How many would you like to purchase?" << endl;
						cout << "Quantity: ";
						cin >> q1;
						cout << endl;
                        break;
                case 2:
                        cout << "How many would you like to purchase?" << endl;
						cout << "Quantity: ";
						cin >> q2;
						cout << endl;
                        break;
                case 3:
                        cout << "How many would you like to purchase?" << endl;
						cout << "Quantity: ";
						cin >> q3;
						cout << endl;
                        break;

                case 4:
						total = (q1*lays) + (q2*luxury) + (q3*marshies);
						
						cout << "Your total amount is: $" << total << endl;
                        break;
                        
                case 0:
						cout << "Enter your cash: ";
						cin >> cash;
						break;
						system("CLS");
						goto receipt;

					}
					
			receipt:
				cout << "meow meow meow " << endl;

        }

}

the selection is keep appearing.

The reason is line 76. The break will end the case and effectively skip the lines below. Line 78 goto receipt; is unnecessary.

Just a quick note, try not to use system("anything")
Here's an overview why:

Move lines 32 to 37 above the while loop (line 29).
