处理类和函数的C ++赋值 [英] C++ assignment dealing with classes and functions
问题描述
我不确定这个学校项目是否正朝着正确的方向前进。我想创建一个3档，基于类的程序，它将允许您运行一个非常简单的比萨店程序。菜单应该与下面显示的类似。
菜单
----------------- -------------------------------------------------- -------------------------
A）你想要多大比例的披萨？
B）您想要什么类型的浇头？
C）显示/下订单当前订单。
D）取消当前订单。
E退出程序。
我只试图完成前2个菜单项。任何人都可以告诉我，我是否朝着正确的方向前进。我需要3天才能完成这项任务，所以任何建议都会非常感激。这是我到目前为止的代码：
I''m not sure if I''m heading in the right direction with this school project. I am suppose to create a 3 file, class based program that will allow you to run a very simple pizza parlor program. The menu should be displayed similar to what is shown below.
MENU
--------------------------------------------------------------------------------------------
A) What size of pizza do you want?
B) What type of toppings do you want?
C) Display/Place current order.
D) Cancel current order.
E) Quit program.
I''ve only attempted to complete the first 2 menu items. Can anyone tell me if I''m heading in the right direction. I have 3 days before I need to finish this so any suggestions would be greatly appreciated. Here''s the code I have so far:
推荐答案
一切看起来目前很好。我注意到的一件事是，当你从main（在switch语句中）调用size（）函数时，你不传递任何参数。但是，在定义的开头，你有一个参数 - 一个参考披萨对象。这在您的文档中也有提及。也许你应该做一个比萨饼，然后使用那个披萨调用大小。您也可以打电话给浇头等，直到客户完成比萨饼，然后将其添加到他们的订单。
Everything looks good so far. One thing I noticed is, when you call the size() function from your main (inside the switch statement), you pass it no arguments. But, in the start of your definition, you have a single argument - a reference pizza object. This is also mentioned in your documentation. Perhaps you should make a pizza, and then call size using that pizza. You can also call toppings, etc. until the customer is done with the pizza, then add it to their order.
我理解你所说的关于不通过我的尺寸功能... ..我可以传递默认值10......但是，不确定你的意思是先制作比萨饼，然后再调用大小和浇头。你的意思是我应该首先在所有默认参数（首选大小和顶级菜单）中制作披萨吗？谢谢你早些时候的回复。将在明天继续研究项目。
I understand what you said about passing nothing to my size function.....I can just pass a default value of 10"......however, not sure what you mean about making a pizza first and then calling size and toppings. Do you mean I should first make a pizza feeding in all the default arguments (first choices of size and topping menu)? Thank you for your earlier reply. Will continue working on project tomorrow.
