- This program is used to replicate the behaviour of a simple text managing software.
- It uses 2 message queues to connect the two processes of the server and client program.
- The server supports 4 basic commands:
- The append command is used to append a new sentence to the server
- The search command is used to find the first instance of a word in the text
- The delete command is used to delete all the instances of a given word in the text.
- The remove command is used to delete the first instance of a given sentence in the text.
- This programs needs to be tested in a Linux environment.
- Requires a gcc version of 9.3.1 or higher
- To run the program first run the makefile to compile the executable file by typing:
$ make- After that two executables with the name of "server" and "client" has been generated which can be run using:
$ ./server
$ ./clientNote that client and server should be ran on two different terminals and in order to establish a valid connection the server program should run before the client program.
Here is an example of how to run the program
After running the program you will be prompted by the program to enter a new command and the server will act accordingly:
Here are some examples of using the said commands:

As you can see remove only works when the given sentence is identical to the one in the server
- Make sure to always the connection using end otherwise the program will not be able to properly close the message queues.
- Avoid using sentences that are more than 35 characters long.
- Avoid white spaces before and after your sentences as this can cause potential problems with remove.
- An optional command named "display" is included inside the program. This command can be accessed by uncommenting the code for it in the server.c file. The main purpose of this command is for debugging purposes.
- Avoid using any form of punctuation in the sentences
