在用户输入C++ 创建包含项目名称、数量和总价的收据,c++,C++,在用户输入No或停止购买后，如何创建一张收据，打印所选商品的所有名称、数量及其总价 我使用了开关，所以我很难找到任何关于收据的参考资料 #include <iostream> using namespace std; char acoustic, electric, drums, piano, music, equip, Yes, No, y, name; int pay, Qty; std::string again; int main() { { cout <&l

计算机科学的一个重要方面是“抽象”。你能试着从账单/收据、数量和价格中抽象出问题，并用对象、变量、类替换它们，并实际解释你试图完成的任务吗？写问题时，试着抓住问题。你可以用两个菜单和两个条目来解释问题。事实上，你可以通过修改问题来解决问题n对于它的要点，您可能会发现您意外地发现了@kishoredbn的观点。您的答案应该直接发布在您的答案中，而不是作为链接。您做了什么？问题出在哪里？您是如何解决的？这是一个只包含代码的答案。为了挽救它，您应该解释提问者做错了什么，突出并解释您的错误用不同的方法解决了问题。问题是我的代码没有问题，我的问题是如何解决。谢谢你的收据代码
