The program uses binary trees to make a hotel reservation program using left and right child pointers. The program should read in a file that contains the number of buildings, the number of rooms in the buildings, type of rooms, and the capacity of each room. The program should then use the binary tree functions such as postorder, preorder, and inorder to perform outputs and inputs for the user such as booking rooms,kind of rooms(single,double,suite, etc), how many people will be in the room, what rooms are available, if building is full, and which building do they prefer. The amount of buildings and rooms in buildings is left up to the programmer.(Verbal instructions were given by instructor and the topic is to make a hotel reservation system using binary trees)(these are additional details)
