I'm trying to write an operating systems backend. It's tempting to use Linux but I'd rather build it custom.
As @notcori said, The C Programming Language by Brian W. Kernighan and Dennis Ritchie.The C programming language, is what I used when I learnt C I find it quite good.
Free-Software in my opinion, is a generally hard-to-explain concept.I don't get all the open source projects. Do people do it to learn coding or help with the project and have a job so they don't care about money? I only plan on open source projects to help with development if I can't do all the work myself. Like I might later help on a project I use, once I'm more fluent with programming. But I first want to make some money off apps.
First of all, to get onto Apple's store, you need to pay about £76($99USD) every year, just to develop apps for Apple. For Android, it's just a one-time fee of £19($25USD). So for Apple, you definitely want to make sure that you have a source of revenue as you'll be paying a fee every year. Without any revenue coming in, you won't be able to pay for that fee unless you have a job at a business which earns you tons. For Android, you don't have to worry about fees other than Google revoking your license to develop apps(This won't really happen unless the app is insecure, untrustworthy and violates privacy laws of COPPA, GDPR etc.) and Google taking a 30% cut of your profit(Apple is the same).NathanBelomy said:I think you can pay for marketing on Apple and Google app stores. I had some music up through a service, but you have to pay annually. I think you can contact them directly to arrange terms. Which is what I'll do next time.
