/* Single-line comment */case';':while((c=getc(fp))!='\n'&&c!=EOF){}break; 因为单行注释的结束有两种可能:一种是到下一行,一种是直接到文件结尾(没有换行符),所以需要那样写。一开始我只写了个while ((c = getc(fp)) != '\n')在最后就会引发一个无限循环的bug。
A very simply sh-like unix shell written in C using recursive descent parser technique. WHY Last summer, I started out writing a shell for my assignment. Thought I'd share it as well. I'll explain this in conjunction with the project hosted in GitHub. Please download it and have your ...
Brainfuck interpreter implemented in C Usage The programm has one argument that is the file which contains the brainfuck code to implement. Brainfuck Brainfuck is an esoteric programming language noted for its extreme minimalism. The language consists of only eight simple commands and an instruction po...
This was my first experience programming in C and it surprised me to discover that I really enjoyed using it. Because of the small language specification very little time was spent reading documentation. That's not to say I did not shoot myself in the foot a good few times or struggled w...
It is a command-line interpreter that is used to run Scala programming in your system on terminal or command prompt.Working of REPL interpreterAs its name depicts its works on read-evaluate-print-repeat principle. This means REPL first reads the statement from the command line then evaluates ...
PEP地址: https://peps.python.org/pep-0703/ PEP 703 – Making the Global Interpreter Lock Optional in CPython Abstract CPython’s global interpreter lock (
One of the nicer aspects of programming in Java is that once the foundation is solid, building upon it is easy. Now that we have our interpreted language parsed into Java objects, implementing the execution engine is straightforward. This column, the thi
A method and system is provided that allows a well-behaved program to execute more quickly than dynamically typed programming languages did in the past, thereby allowing a the dynamically typed language to be competitive with static declarative programming languages. A method includes converting lines ...
One notable initiative in this context is the Global Interpreter Lock Removal (GILR) project. This ongoing effort seeks to explore the feasibility of removing the GIL from the CPython interpreter, thereby allowing multiple threads to execute Python bytecode simultaneously. While this endeavor presents...
