Projects I did a few years ago (between 2009 and 2010) when I was a student and began programming.

Using C standard library was forbidden for some project so I reinvented the wheel a few times.

I used to work on FreeBSD when I did this projects. Some are also working under other Linux/Unix environments, but unfortunatly not all of them.

Find the biggest square in a map.

./bsq map_file

Check test.txt to see a map file example.

You can also activate the color mode :

./bsq -colors map_file

This project is a function that returns a line read from a file descriptor.

char *get_next_line(const int fd);

My own malloc implementation.

man malloc

The communication between the client and the server only uses signals. The server is able to handle various clients following each others. Only allowed to use the signals SIGUSR1 and SIGUSR2.

$ ./server
PID=7845

$ ./client 7845 "This is a message"

The server will then display "This is a message".

A simple multi-user dungeon server.

A simple ftp server with a command-line client

A simple irc server with a gtk client.

My own implementation of the C standard library.

My own system function ls [-lRdrt] [FILE]

man ls

My own implementation of the printf function from the C standard library.

int my_printf(const char * restrict format, ...);

man printf

A termcaps item selector. It takes the parameters and convert them into a selectable list.

$ ./my_select "lol" "test "etc"
lol
test
etc

SPACE: Select an item. ENTER: Display selected items on standard ouput.

My own unix shell.

This project handle the ’;’, the pipes ’|’ and the four redirections ’>’, ’<’, ’»’ and ’«’.

$ ./mysh

Display a number in french.

$ ./ntn 42
quarante-deux

A solution to the dining philosophers problem.

$ ./philosophes

This program take the parameters as a list of parameters (no doubles, all numbers are valid and fit in an integer). This program display the series of operations allowing to sort the list. Operations are displayed separated by a space, no space at the start or the end, and with a newline at the end. The goal is to sort the list with the fewest operations possible.

$ ./push_swap 2 1 3 6 5 8
sa pb pb pb sa pa pa pa

A sudoku solver. Check test.txt to see a map file example. You can chain one or many maps in the same file.

$ ./sudoki-bi map_file
