(Solved by Humans)-A number of user can log into a server machine at any point of

Question

A number of user can log into a server machine at any point of time. Given the system logs of a server in a file, and list of users and a time, develop an algorithm and write a C++ code to check if the users were logged in the server during the specified time. Server log files will contain stream of characters with details such as user name of the person, log in time (separated by ':') and log off time (separated by ':'). If the user was loggined in during the time specified then print ?Logged in? and print ?Not logged in? otherwise. A delimiter '$' is used to separate every field and reord of user in the input file. Login time details is given in 24 hour format. Login details of two users is given as follows in the file:

janaki$01:03:04$02:05:10$Meena$10:05:04$13:15:10$

The above line indicates that the first user name is janaki, login time is 01:03:04 and log off time is 02:05:10, and the second user name is Meena, log in time is 10:05:04 and log off time is 13:15:10. When a user janaki is checked for log in by time 01, 10, 25 the program must print ?Logged in? and when user checks for the user janaki for log in by time 02, 06, 25 the program must print ?Not logged in?.

Develop OOP models as required.

Hint: date and time are predefined names in g++ so don't use those names your class/struct as date and time
