This is a code that i found in internet about hotel management program. I'm a beginner in C++ and my purpose was to compile the code with dev c++ and to understand how it works, but it has some errors that i cannot fix them. I tried everything i know about C++, but no hope. When i compile the program i get no errors and i can use some functions of the program like adding rooms and searching rooms, but when i want to use the reserve room function the program crashes. If someone could compile the program and tell me what the problem is i would really appreciate it. I really want to learn C++ programming language, but i need some help from the pros. p.s(I apologize if the code is not properly indented, because as I sad I'm a beginner). Thank You in Advance
