Which programming language is best for a beginner to start coding games

That depends on what experience in programming you currently have and the type of games you plan to develop. For a total beginner I would recommend you start with BASIC and become familiar with coding principals. If you already have some programming experience then you can use one of the many gaming frameworks to develop your game ideas using scripts and templates. If you want to take it further then Java is probably the best way to go forward. C++ has quite a steep learning curve, but that would be the next logical step, followed by assembler language. After that the world is your oyster. If you want to become a professional console games developer then college or university is the best route unless you have particularly deep pockets and a gaming licence to develop for XBOX and PS3.
