问题描述
我必须从头开始写这个，我该怎么做才能开始？我想要编写一个程序，计算每个费用分类中有多少人在某一天乘坐地铁（这是一组if语句）。地铁有三种费用分类：学生（17岁或以下）成人和高级（65岁或以上）。我必须假设售票员有一台笔记本电脑并进入每个骑手的年龄。您的指示告诉指挥在当天结束时输入-1以终止数据输入过程（循环将导致程序继续直到输入-1）。
输入-1后停止数据输入过程，您的程序必须显示每个费用类别中的客户数量。
从哪里开始？任何帮助将不胜感激
I have to write this from scratch, what do I do to start? I''m suppose to write a program that counts how many of each fee classification rode the subway on a given day (this is a set of if statements). The subway has three fee classifications: students (17 years old or less) adult, and senior (65 years old or more). I have to assume that the conductor has a laptop and enters the age of each rider. Your instructions tell the conductor to enter a -1 at the end of the day to terminate the data entry process ( a loop will cause the program to continue until a -1 is entered).
After the -1 is entered to stop the data entry process, your program must display the number of customers in each fee category.
Where to start? Any help would be greatly appreciated
推荐答案
从创建一个while循环开始，让你输入数字并在输入-1时停止（或者可以是任何减值）
Start with creating a while loop that lets you enter numbers and stops when you enter a -1 (or may be any minus value)
你需要使用cin，你能写一行吗？允许用户输入数字。
Well you are going to need to use cin, can you write a single line that allows the user to input a number.
