I have read about peek() and putback(). I am pretty sure I need to implement these two functions but quite frankly I am not sure how to go about doing this. Any help is appreciated. Thank you.

The final code should be OS independent in other words it should know which enviroment it is running on. Should I declare #ifdef __WIN32 in the header file or it is built in? I am not too familiar with driver development in win. Everytime I compiled in VIsual Studio I always get an error msg unexpected #endif. My code is like Code::main(){ #ifndef __WIN32 *** code #else ***code #endif } Any ideas?Thanks, Sat, 09 Feb 2008 19:15:19 -0800 http://www.w3exchange.com/view_topic.php?pid=6496#6496 6496@http://www.w3exchange.com Topic: Parsing Numbers from a String Message: I have the following example and need to parse only the numbers from the string:From:EG2594To:2594or, From: EG2594_1To:2594Then I need to add a P to the extracted numbers, so it would end up as:P2594as my output.What is the best, simplest way to do this in unix C?compare each character's ASCII value?

The advantage of inline functions is that they have no overhead associated with the function call and return mechanism. That means inline functions can be executed much faster than normal functions.Example: Code::inline void sum() { int i,sum=0; for(i=0;i<10;i++) sum=sum+i; cout<<sum; } Fri, 18 Jan 2008 19:40:31 -0800 http://www.w3exchange.com/view_topic.php?pid=6401#6401 6401@http://www.w3exchange.com Topic: How much you know in C - (C Quiz) Message: Rate your self in C.

C++ are better because, You can do multiline comments, XML comments, single line comments, etc. Also you can place a region inside a function. So I like this than VB.

In C running in the Unix environment, there are many ways of getting the directory listing. One I know is to use the ftw library (the way I currently implement it), the other is to pipe from the ls, also sometimes you could use dirent.h. I realize that this is an OS dependent thing. If somebody knows an the easier way to get a list of files or directories in C please share (Yes, I googled this. However, I did not find anything I did not already know).

Oddly-shaped windows are created using window regions or (in Win2K+) layered windows. I don't know of any tutorials dedicated to this, but Google should help there.

And if so, can any point me to any tutorials or informational sites that would help me in creating and implementing my own? Sun, 20 Aug 2006 07:07:11 -0700
