This repo is to track progress, and gather notes from CS50's Introduction to Computer Science.
- Kick off CS50 with Study Group
- Learn CS from Scratch
- Battle with Recursion
- Spell-Checker with Hash Table Dictionary
- What Makes a Good Hash Function?
- Valgrind and Memory Issues
- Step Away From Stack Overflow
ide.cs50.io is fantastic for getting started with CS50, but I wanted to have some of my code in this repo, and to run these projects in my local terminal. Here's an approach to that:
- Install cs50/libcs50
- Compile with for example
gcc -lcs50 -o recursion recursion.c
- Run program
./recursion
