I got this assignment from my college:
To create a working Compiler or Interpreter You need to design your own Language And build the compiler using Java or preferably C. This is one scary nightmare...dang....I wish I can just wake me up... but I can't this is not a nightmare. T_T Btw, does anyone here has any experience on creating compiler or interpreter using C? I am designing a language which is the combination of C and PHP. And I need help. |

Hi;
Any more parameters for this assignment? number of statements, functions etc.. it sounds hard, but just take a deep breath... start with the actual syntax: identifiers, functions, operators, separators, etc... decide what legal and illegal syntax is then write your pattern-matching code to look for these things now that you can identify the parts of your language, all you need to do is translate it to C and compile and voila, u r done. start with a simple arithmetic language, i.e. make sure the operators are infix (or postfix or prefix or whatever u like). make sure the operands are valid (i.e. numeric) now expand it by adding variables. make sure variables are declared before being used. i think u see where I am going now... good luck! - arp |

Hi!
I wrote C interpreter, Pascal interpreter, Icon interpreter, C->Pascal translator and C->ICON translator (everything in ANSI C) You should read something about Flex/Bison (lex/YACC) (use google to find it) -- eldeo |

yeah....
first of all design the syntax... and get the patterns/ regular expressions to identify the tokens( identifier/variable, constructs, expressions etc). you can then use lex to generate a program which reads the source and generates the tokens... call this program from your program.. now that u have the tokens... process then in your program accordingly.... I have heard of yacc but never used it... just find out more abt it and c if that would help... all the best... rest assured that though it is difficult, it would be very satisfying once u c the result.... |

Well, firstly, do not resurrect old threads.
Anyway... What do u mean, a 'C' compiler? A compiler written in C or a compiler that converts C -> executable file? For the first one... try reading some of the posts above, they are really useful. Any in-detail questions? |
