C language before graduation

Before graduation, I learned C language-general Linux technology-Linux programming and kernel information. The following is a detailed description. I did not say C ++. Although C does not work much now, programmers who have mastered various programming languages actually use C for Communication (lingua franca). More importantly, C is closer to machine language than some "modern" languages. No matter what popular spam language (trendy junk) I teach in college, you have to spend at least one semester approaching the machine.

Otherwise, you cannot use advanced languages to write efficient code. This means that you won't have the chance to write a compiler or an operating system, maybe it's a better programming job; others won't believe that you can design an architecture for a large project. No matter how many advanced control structures you know, you know how to handle errors. If you cannot explain why while (* s ++ = * t ++ ); it means to copy strings (and for you this is the most natural and understandable code in the world ), then you are programming on superstition ).

For example, a doctor gives you a prescription if he doesn't know the basic anatomy. If you ask the doctor why the doctor prescribed this medicine instead of that medicine, he will say that because the pharmaceutical sales representative said this medicine is useful.
