Is C a foundational language or just a popular one?

Question

Programming

Good afternoon, tell me, is C the closest language after assembler to machine code and is the standard from which all other languages ​​\u200b\u200bcame?
Or are most languages ​​written exclusively from machine code?
And how, for example, in assembler, could they set the load command in 4 bytes LOAD or processors are created directly for languages, and not languages ​​for processors?

Answer 1

Language processors are a few historical examples, like the lisp machine.
Usually, languages ​​are created to solve specific problems, moreover, they are trying to be made portable between processors.
This is where C and C++ really help, because they are cross-platform languages, for which the principle is that you pay (spend resources on) only those features of the language that you use.
That is why most interpreters and runtime environments for non-compiled (Python) and JIT-compiled (Java) languages ​​are made in C or C++, or are compilers in C++ (KPHP)
