And the key thing you have to do is take a program in B and produce a program in C that's equivalent, that has the same behavior, and then you have to rely on there already being an implementation for C. So, if C is binary code, the kind of code that your computer hardware can run directly, then you can think of the computer hardware as an implementation of C, and so your implementation of B just translates to a program in C and then, you run it on the hardware. There are two general approaches to programming language implementation: * Interpretation: An interpreter takes as input a program in some language, and performs the actions written in that language on some machine. 189 0 obj endobj >> endobj 271 0 obj << 285 0 obj << << /S /GoTo /D (section.5.3) >> 33 0 obj 193 0 obj endobj 124 0 obj If there is one programming language that has the potential to reshape the future, it is Swift.

They take a program, which is written down in racket using these trees, and they produce an answer in the language. And I wish to emphasize that this really does not make very much sense and I for one I like to politely correct people when they repeat these, these old sayings that are just by definition not just wrong but don't really make sense.
