 | >> what is the best Torrent program I like uTorrent and bittorent. The best torrent program is a completely separate issue from pirating/copyrighting. There are plenty of artists/developers who WANT their stuff out there for free and uTorrent and bittorrent and the filesharing sites are a God-Send. With them, there's … |
| | The first step is to get the non-varying "variables" out of there. [code] int fun(int n) { if(n>2000) return n-40; if(n<=2000) return fun(50+fun(50+fun(50+fun(50+n)))); }[/code] Second step is to simplify it by getting rid of the second if. [code] int fun(int n) { if(n>2000) { return n-40; } return fun(50+fun(50+fun(50+fun(50+n)))); }[/code] … |
 | Re: Mail >> How can I send an email through C++. You don't. Or at least you don't through standard C++. You need to either use something like libcurl and pass this information to some language like PHP which DOES have built-in mail functionality or you need to find some other C++ … |

 | >> But some people and scientist said that he should be given a proper burial and respected by the west. Who said that? Respected by the west? I don't think so. Supposedly they did give him a "proper" burial. The extra bonus is that since he's buried at sea, the … |
| | Re: FLOAT Problem.. >> but it seems to be working only in int and char data type num1 is uninitialized so it could be anything, which means score could be anything. It shouldn't work at all, whether you're using floats, ints, chars, whatever. [quote] [code] //if num and num1 is a digit, continue … |
| | OK, the eventual goal of my project is a kind of word insert/delete/replace. You read a file... "The quick brown fox jumps over the lazy dog." and you can delete all instances of "fox", replace "fox" with "cat", insert "giraffe" wherever you want, etc. Word processing stuff. So I figured …  |

| | You're either calculating tax, printing a list, or sorting, but not all three at the same time. They are three distinct tasks and should be handled as such. Combine them at your own peril. Aside from that, I see no attempt at a bubble sort anywhere, so I have no … |
| | Before one adds a term, one must find out whether said term exists. If so, replace. If not, add. So first iterate through all the terms and look for the exponent. If it exists, that's the easy case. Replace the coefficient and you're done. If not, add the term. First, … |
| | Line 3 - [ICODE]char name[20];[/ICODE] Perfectly acceptable, but you're using C++, so if there is not a reason not to, take advantage of the string class. [code] string name; [/code] You might perhaps want to keep track of last and first name since that is how the file is organized. … |

| | Several things can go wrong in a program. Among them... [LIST=1] [*]Functions are incorrect. [*]Function parameter passing is incorrect. [*]Something is wrong in the calling function.

 | They're so hard to rate. First you have to agree on who's qualified to rate them, then you have to agree on some criteria. As the ratings show, depending on who you ask and what the criteria are, you can get some dramatically different tables. However, good old Abe Lincoln …  |
| | I imagine you're looking at something multi-threaded or multi-processed and non-portable. What's your background on that? Lots of good threads out there, including this one. [url]http://www.daniweb.com/software-development/cpp/threads/105105[/url] I think the technique will depend on the OS, your exact needs, and your experience level. |
| | The psudocode just confuses me. Perhaps post the "before" and "after" of the file and what's changing? Is this something like you're "setting" bit 2 of the SOT portion of the file to 1? you need to traverse the file, find "SOT", then find the "bit 2", then find the … |

You can't do that in C++. Try moving line 32 to line 10. With those two errors, the compiler will get confused and give you hundreds of errors that aren't … |
| | I don't think it has anything to do with user input. The algorithm itself is flawed, recursion or no recursion. It immediately flunks for a non-recursive example. One disk, three pegs. One move from either peg 0 to peg 2 or peg 1 to peg 3, depending on how you're … |

| | Regardless of anything else, the whole thing breaks the first time you hit line 84 as far as I can tell. What's st[0]? Is st an array? If so, you never set aside any memory for it, or at least not soon enough. >> This line(cd=new CD[putCount() + 1])... Does … |
| | I question the wisdom of using [ICODE]while(cin)[/ICODE] as a sentinel representing "finished entering data". That might work just fine for a file, but this isn't a file. An example of how things should end up in the array after everything is done, given certain user input, might be in order, … |

| | I am interpreting the goal as follows. Please confirm whether my understanding is accurate. You have ten items. Each item has four data points. High numbers are "good". Low numbers are "bad". Increasing numbers are "good", decreasing numbers are "bad". So "memory" has the trend you are looking for. Things … |

| | Line 11 doesn't make much sense to me. col is 1 and never changes. That means the "loop" will only happen once, so not much of a loop. qu is always 0. Therefore I am quite surprised by this statement... [quote] The function I wrote below works for col 1, … |
