Learn C on Linux
Came across this article of ways to Learn C on Linux which took me back to my 3rd real programming job.
It was with a software house mainly working with C/C++ on Linux/ Unix and embedded systems.
My first real experience use C/C++ in a professional environment, happy days with a good bunch of geeks.
If you’ve never tried it before it would be a good change from more recent languages to learn C for a challenge.
