On his new C Learning website, Peter explains: "C Learning is a brand new service for C programmers trying to get to grips with this complex language. Despite its age, C remains a crucially important computer language to many areas of Software Engineering." He goes on to say: "C Learning is a subscription-based service which offers quick answers to your questions about C, specific to your problem. You can send your questions, code, problems, etc. and have them answered in a timely manner."
As with the popular Unix Porting Project, C Learning is based on a six month subscription, of which the cost is currently at an introductory rate of 40 of your Great British Pounds (normally 60) or 65 US Dollars (normally 95).
