C++ While Loops

Question

У меня возникли проблемы с запуском цикла while. Я очень начинающий кодер, и я сделал много попыток без успеха, чтобы сделать эту работу. Мне нужна помощь ПОЖАЛУЙСТА! Пожалуйста, будьте очень конкретны и с условиями мирян с вашей помощью, так как я новичок в этом.

#include <iostream> 
#include <string>

    string mystr1; 
    string mystr2; 

    cout << "Please provide your first and last name" << endl; 

    getline (cin, mystr1); 

    cout << endl; 

    cout << "Please provide your shipping address" << endl; 

    getline (cin, mystr2); 

    cout << endl; 

    cout << "Hello " << mystr1 << " and welcome to Faulk Couture  
    Handbags Boutique" << endl; // prints Hello and welcome to Faulk 
    Couture Handbags Boutique 

    cout << endl;

    Crafted in lightweight pebble leather with a bit of sheen, this

Answer 1

Вы прекращаете свое время цикл точки с запятой, поэтому она не входя в то время цикла

Вот петля в то время как без запятой

while (choice==1) { 
    cout << "To purchase another bag, please enter 1 (anything else to 
    quit)" << endl; 

    cin >> choice; 

    cout << "Please enter the product number for your next bag choice" << 
    endl; 

    cin >> product; 

    cout << "The respective price for this bag is: " << endl; 

    cin >> cost; 

    cout << "Please enter the quantity you would like to purchase for this 
bag choice" << endl; 

    cin >> amount; 

    total = cost*amount; 

    cout <<"Your total purchase price for " <<amount<< " qty of product 
number " <<product<< " is " <<total<<"."<< endl; 
}
