Like a more specific question than "I've got problems, and here's a 3/4 Meg ZIP file for you to dig through" ?

Doesn't make much sense here either [url]http://cboard.cprogramming.com/showthread.php?t=110087[/url]

rand() should be pretty quick, because it is pretty simple. You might try [code] for ( i = 0 ; i < 1E7 ; i++ ) { num = 42; // was num = rand(); } [/code] Just to make sure that it's rand() which is the bottleneck, and not …

It's the same old story - [url]http://www.daniweb.com/forums/thread161400.html[/url] Try it, and find out. Otherwise, we might just start lying about the answer just to see if you'll believe everything we say, only to find yourself with a crap mark on your assignment.

So where's the if / else logic around your fork calls? Because I can't see how you can possibly get the output, from the code you supply. I mean [code] /* fork process one here */ fork(); pid1 = getpid(); //call process1 to increase shared memory counter process1(); fprintf(stderr,"Hello from …

It's because scanf doesn't read a whole line. It only reads what it needs. So if you type 123\n and you remove 123 with your scanf("%d"), then that leaves the \n for something else to deal with. That something else (in your case) is scanf("%c") which reads the next char …

The output of [ICODE]od -Ax -t x1z /home/mmeclimate/test/test.dat[/ICODE] is my preferred way of dumping binary data in an unambiguous textual representation.

[url]http://msdn.microsoft.com/en-us/library/aa385103.aspx[/url] 1. You don't check the return result. 2. You don't check ret either 3. Your cout assumes that buffer is a \0 terminated string (it isn't).

Why would you need a raw socket, when a regular one would work just fine? Just read "beej" and study the client/server example.

Looks like chr(7) to me, not chr(13)

The first one is initialisation, the second one is assignment. Arrays cannot be assigned in either C or C++. You also need to get out of the "arrays are pointers" mode of thinking. [url]http://c-faq.com/aryptr/index.html[/url]

If you can't figure out how to use code tags after 20+ posts, and people keeping on telling you about them, then I have to say that programming isn't for you. And your choice of topic titles borders on the useless as well. [url]http://www.catb.org/~esr/faqs/smart-questions.html#bespecific[/url]

Well it was suggested in half a dozen places that you should use code tags. But you ignored all of them, so really what would be the point in spending any more effort on a 7th or 8th attempt.

There are lots of them. [url]http://en.wikipedia.org/wiki/Widget_toolkit[/url]

Well since you bumped a 6-month old thread just to ask a google question, try this [url]http://www.letmegooglethatforyou.com/?q=free+IDE[/url] Which in itself was bumped (uselessly) from a 16 month slumber. But then again, it is your own personal support thread, so perhaps it's OK.

Convert to a string using say sprintf(c) or stringstream(c++) Then output the string as you know how to.

trip.input(); trip.set_mile(new_miles,new_fuel); The first one reads input and assigns the class member vars. The second just trashes the data with the uninitialised values in main. Just delete this line.

The first error was not reading all the forum rules about using code tags.

I dunno, 70 posts, and you've managed to figure out code tags. But it's still unindented crap which is hard to read. Translation - you're being ignored.
