hi.. I must implement an interpreter in C programming language that will get the source code of a program in text file format and execute it.
but i don't know C language enough to write this interpreter. so I need this interpreter code that is written with C language.(or it can be C++) I searched this codes in google and some websites, but codes which I found are useless..
if you can help me, you gladden me.
please help me.. this effects my graduation.. 
*************************
a part from my homework;
Your interpreter program will accept and execute statements below:
• int variable_name
• cin>> variable_name
• cout<< variable_name
• variable_name = infix arithmetic expression (variable names, +, -, *, /, and parentheses (..)).
• for loop
• if else statement
(your interpreter does not need to recognize and execute nested for and if/else statements .
It should give error messages. Possible syntactic errors relating source code input are:
• Undefined variable <variable_name>
• Paranthesis mismatch
• Curly brackets mismatch
For the arithmetic expression evaluation you are free to use directly an existing evaluator program source code like polish notation within your interpreter.

Then you don't deserve to pass. What makes you think that people who earned their degree want to help you become their under skilled co worker ?
If you've done your course work, you'll probably find you CAN do this if you try. You'll also find people here helpful if you post specific questions when you get stuck rather than asking for someone to do it all for you.

Hey! I resent that remark. I don't have a degree, and I still don't want to help them become my underskilled co-worker...  (I have, however, honed my skills for 25 years, even if some days it doesn't seem like I bothered).
It never ceases to amaze me how stupid some people can be;
"Hmm. I have an assignment in a language I can't write in. I know, I'll get someone else to provide the code."
Does it never occur to them that they might have to explain how it works?
I confess, during my Computer Studies classes (I studied to GCE O & A levels in the UK), I did write 3 other people's projects for them, but to put it into context, they were all girls I was dating at the time! Nowadays, I charge money instead 
Plus ca change, and all that...
(Of course, if I'd spent more time working in class instead of (ahem) socialising, who knows, I might have studied at University and got that degree)

Neither do I. I was just making a contrast that some have gone through what he's trying to do, on their own merits.

Christian, I think you missed my real point; even us 'unqualified' guys wouldn't want people that stupid as coworkers 
Christian Graus wrote: ROTFL !!!
See, before CodeProject, I had a social life....
(Actually, I married one of them, divorced a few years and two kids later, remarried again some time later - my current wife [I always call her that, it keeps her on her toes] understands the developer lifestyle, so I'm still married)

No, I got it, just wanted to make sure you realised I wasn't being a snob.

LOL - I should try that.

Mine is having a tough time with all the travel, I have to admit.

thanks for our all advices and depreciatory words...
I know this is only my homework. but this is not a coding course and my excellent(!) instructor wants this homework. thus, for pass this course; he orientate us to find codes. consequently, I and my friends search this codes in internet compulsorily. we found some codes but they are very advanced. so I though to ask my question in this area..
I don't discuss about deserve to pass.. because in this course, our instructor deserve to be dismiss... 
Lastly; thanks my instructor for cause to read this dirty sentences..

Send the control a LVM_SETITEM message.

Actually, that's the notification message (LVN_ITEMCHANGED) that a list control control sends its parent when an item has changed. Perhaps you are thinking of the LB_SETCURSEL message.

Hello all,
I have a working BIG MFC project X. Now I want to create a new project Y(or another interface) that will use the older MFC project X as a library from which classes and methods are called. I changed the general properties of the X from .exe to .lib and Linked Y to X in the linker properties.
The problem is that I lost all linker options that were in X (I used to link X to other libraries). Whatis the solution for this?
Thank you very much.
Regards

Create a temporary DLL project and make a note of what linker options are used. Incorporate those into X.

Do you mean that I should creat a DLL project that link to these libraries and then put this DLL in X, thus X is linked to the libraries?
How to create this DLL project and how to link it to X?

Notice the word "temporary" in my suggestion?

Use MFC's AppWizard.

I can't get you. This is complicated for me. I am a beginner. Can you explain in more details and easier steps?

It doesn't get any easier than what I've already provided. Since you have already created a "BIG MFC project," we must assume that you are at least somewhat familiar with the process. In any case, see here.

Dont take the "BIG" word to that extent. It is big in core not in interface. I'll check the links and go back to u soon.
Thanks anyway.
