我正在开发一个需要输入/输出多种数据类型的程序，包括代表顾客正在预订的运动类型的char，代表他们年龄的int，以及根据顾客年龄和运动他们希望保留一个位置的输出，这代表他们的保险费率。“/ p>
因此，简化程序的逻辑是输入程序 - ＆gt;选择添加预订 - ＆gt;使用char进入运动 - ＆gt;使用int输入年龄 - >根据这些情况计算保险费率并将其返回以显示给用户。
我将使用数组作为char，存储他们希望参与的运动，一个年龄数组，一个索引整数，它将跟踪用户输入数据的阵列中的哪个点，以及我可能需要为保险费率制作一个数组。
无论如何，TL; DR我该如何说，访问数组的特定元素以打印出类似于＆＃34; patron_age[index]年龄sport_type[index]保留会话#include <iostream>

我假设您要完成print_all和print_by_sport函数。
首先，你的问题不明确和准确。在发布下一个问题之前，请务必阅读https://stackoverflow.com/questions/how-to-ask。
您必须为参与游戏的每个人分配唯一的用户ID，否则您无法区分参与相同年龄的同一游戏的两个人。
因为在你的程序中你已经定义了名为“index”的变量，可以用作用户ID。
最初在程序启动时将用户ID保持为零。
IMO，最好为不同的游戏维护不同的阵列。因为在打印特定运动的信息方面，它只是分散在一个阵列中，你必须循环整个并检查该特定运动。）目前您已定义了三个游戏。
保留三个阵列
unsigned int flying_age[100] = {0};
unsigned int gliding_age[100] = {0};
unsigned int hang-gliding_age[100] = {0};
当程序开始初始化索引（USER_ID）为0时。
希望这有帮助。
