Hello, I'm a newly graduated engineer and planning on travelling for 12 months before settling into the real world. I have 12 months to develop my skills in programming languages C++ or C#, I only have basic knowledge of C from playing with PLC software / hardware etc. My question is is there a dominant programming language out there used in industry, or does it vary from company to company? As I don't want to spend a long period of time learning something I may find out dated etc? Thanks.
