C中的铁路预订系统
铁路订票系统由C编程实现。这和我们在网上订票时看到的一样。在此软件中预订火车票时，将遵循以下一系列步骤-
- 第一步是提供乘客总数并提交所有必要的乘客详细信息。
- 下一步是输入源和目标。
- 将出现可用列车列表。其中，用户必须选择一个。
- 将评估票证价值。系统将通过显示座位矩阵要求输入座位选择。最后，屏幕上会生成收据。
方法：
从那些“Hello World”程序中升级。学习实现堆、堆栈、链表等数据结构！查看我们的 C 数据结构课程，立即开始学习。
- 第一步是实施一个结构来获取乘客的详细信息，如姓名、性别和年龄。
- 五个函数被定义为 void details(int), void add_node(char, char, int), int Seat(int), int cal(int, int, int), void bill(int, int) 才能顺利工作。
- 结构中有三个元素，如两个字符串，一个是乘客姓名和性别，一个是乘客年龄。此外，将使用结构指针来帮助链接另一位乘客的下一个节点。它类似于链表。
- 定义了字符数组，并且全局定义了一些整数数组。
- 将乘客数量作为输入，并将这些详细信息发送到details()函数。
- 执行 for 循环以获取每个乘客的详细信息。用户输入的详细信息将发送到 add_node()函数。
- 在 add_node函数中，每个细节都将存储在每个乘客的节点中。这些节点将相互链接。这是基于链表概念。
- 输入源地点、目的地地点，它会提供一些可用的火车选择。基于该用户必须给出一个选择。然后调用cal()函数。
- 在cal()函数中，用户必须选择 sleeper 或 ac 类。如果用户选择 ac 类，则会打开另外三个选项，用户必须根据系统将在金额上添加 18% 的 GST 并构成总金额来提供另一个选择。
- 调用Seat()函数，其中将向用户提供座位矩阵，用户必须选择与乘客数量相同的座位。
- 最后，调用bill()函数，其中将显示包含所有必要详细信息的总账单金额。
下面是上述方法的实现：
