Варианты текстовых приключений в выражениях if и else if и else в C ++

Question

Здравствуйте, я очень новичок в C ++.

Я делаю тестовое текстовое приключение, но не могу получить приключение, чтобы выбрать опцию просмотра моего персонажа Кюн.

Что я делаю не так?

Я пытаюсь заставить программу просматривать Kyung с помощью выражения else if, но программа заканчивается, когда я набираю "TURN", чтобы попытаться просмотреть kyung. Я не знаю, что я делаю неправильно.

#include <iostream>

using namespace std;



int main()
{

    string choice;
    cout << "                 |                                          " << endl;
    cout << "                 |                                          " << endl;
    cout << "                 |                                          " << endl;

Answer 1

Это просто потому, что ваш выбор TURN находится внутри выбора INSPECT:

if(choice == "INSPECT") {

  ... 

  if(choice == "BACK") {
  cout << "You went back." << endl;
     goto stupid2;
  } else if(choice == "TURN"){
     ...
  }

}

, вы должны переместить его на TURN из блока INSPECT, если это так:

if(choice == "INSPECT") {
  ...
}
... 

if(choice == "BACK") {
  cout << "You went back." << endl;
  goto stupid2;

} else if(choice == "TURN"){
     ...
}

Вам следует избегать использования goto в своем коде, потому что отладка кода goto действительно сложна, пожалуйста, читайте больше на Код спагетти .Вы можете реструктурировать свой код, используя цикл while для игрового цикла и function для каждого на ваш выбор.

Вот рабочая версия с while петлей:
