During summer 2015, I had the opportunity to follow the Harvard online course of Introduction to Compuer Science (CS50x), taught by David J. Malan.
During these 180 hours of courses, I have made different projects and you can find the source code here.
The following problem sets (pset) are currently online:
##pset1 A really simple problem set to learn the basic of coding and C. ###hello.c The most simple program in the world that prints "Hello world!" to the console. ###mario.c Fun C program that prints a semi-pyramid to the consol ###greedy.c Really useful and simple program that indicate the simple way to give change.
##pset2 A problem set to understand ASCII math. ###initials.c Really simple program that retreives the initials of a given name. ###caesar.c & viginiere.c This is two cryptographic programs. Really fun to do (and to use!)
##pset3 A fun problem set, introducing graphic user interface ###find.c Simple program to find something in a given input. Practicing binary search. ###breakout.c A fun game developed in C, wiht a graphic interface library from Standford
##pset4 A really fun problem set to learn how to work and the structure of files images ###recover.c This program in C aims to recover data from a lost sd card ###whodunit.c A image with a lot of red points was given, and this programs aims to delete every red pixels ###resize.c Simple program that resize a given image
##pset5 Maybe the hardest problem set. The objective was to implement a spell checker with the best memory usage ##dictionnary.c This file is used to run spell.c. A great exercise to understand hashtable and linked list. Hard a really hard time on this one, but was fun after all.
##pset6 One my favorite pset because it was really gratifying, and was able to wrote a HTTP server in C. How awesome is that? ##server.c This is my own HTTP server :)
##pset7 Also one of my favorite problem set which goal was to code a little website using JavaScript (jQuery here), HTML/CSS, PHP and MySQL. This website is a stock market game where the user can create an account, buy and sell shares (based on Yahoo Finance), see its history and add fund to its portfolio.
##pset8 Really fun problem set that is using the Google Maps JavaScript API v3. This website, coded thanks to JavaScript (no jQuery here), HTML/CSS, MySQL and PHP, allows the user to consult a Google Map with Google News embedded.
