I see its now been 8 days since you originally made this thread and thankfully still have surviced (not killed yourself) :) I assume that was just an exaggeration -- would you like me to change the title of this thread ?

Is that some wife's tale you quoted ? :)

That's exactly why drivers should not eat while driving. At his age he needs to give up that crap anyway to avoid getting completly clogged artires and heart attack.

The second problem I've seen occasionally too. Never attempted to mark forums as read so never experienced the first problem.

create a new project then add the files to it.

>>Provide for the "worst case in which all 20 numbers are different >>Use the smallest possible array to solve this problem. The answer is an array of 20. please post your pseudo code that you have written so far.

It generates the same set of numbers every time because you didn't seed it. Do this: [code] #include <ctime> int main() { srand( time(0) ); // see the random number generator // other code here } [/code]

you need to use an os-specific function to delay the program a bit inside the loop. If you are using MS-Windows you can include windows.h and call [b]Sleep[/b] function. >>cout<<"\010."<<flush; Thats poorly written. flush is not normally needed.

[QUOTE=Darrace;446701]wanna learn just cause it seems fun[/QUOTE] Its also illegal, so I'm closing this thread.

Every character you can type on the keyboard is entered into your program as an int. The [b]char[/b] data type is really a one-byte integer. There is no such thing in C and C++ as a [b]character[/b] data type. So if the '@' character is causing your program problems then …

Nice code you posted -- why did you post it ? (my crystle ball is broken tonight)

Would you please also post [b]resource.h[/b] so that I can compile it ?

what compiler are [b]we[/b] using ? And why are [b]we[/b] mixing C functions with c++ code? If you are going to write are c++ program then do so. Yea I know c++ language supports those c functions but its a lot better style to use all c++.

First, don't allocate the buffers like that. Its just toooo much! If you want to use dynamic allocation then allocate them before the loop and delete them after the loop terminates. >>But I don't know how to move to the next item Increment the second parameter ??

I bought an Acer a few years ago from Best Buy because it seemed to be a good idea at the time -- no screws that is. After I got it home, opened the case to add another card, I had a terrible time trying to get it put back …

why don't you replace the ifstream and ofstream objects with just one fstream object then open it for both input and output, in binary mode.

how is [b]indata[/b] declared ? Is it a member of istream?

This is a typical binary search algorithm. Before doing anything initialize the value of max to be 100 (because that's what you said would be the maximum possible value) and min to be 1 (for the same reason). You should delete lines 36 and 46 because those two are initialized …

The [b]flush[/b] function forces data to be written to a disk data file (or some other output stream). There is a couple ways I can think of to solve your problem: 1. write each value to a file then read the values back and display them when the user is …

do you know how to code bubble sort? or any other sorting algorithm ? If yes, then sorting structures is nearly the same thing except instead of swapping integers you swap whole structures. But it runs a lot faster if you use an array of pointers to structures instead of …

post the rest of that function becase what you posted is not enough to tell us anything about the problem you have.

Minutes is calculated like this (I think). You have to subtract from original value of secs the number of seconds in hrs variable then mod the result with 60 (60 seconds in one minute). [code] secs -= (hours * sph); minutes = secs % 60; [/code] Now the remaining seconds …

show us the code you have written so far. Do you know how to use [b]vector[/b] class? That is the easiest array to use. You can make a [b]vector[/b] of [b]string[/b] objects [code] std::vector<std::string> theArray; [/code]

you must have changed something. post new code where the problem is.

You can't reliably test for equality of floats due the the way they are represented in memory. May floats can't be represented exactly. So you can't reliably use the == operator. You might try something like this: [code] if( (newdeck > .449) && (newdeck <= .450) { // blabla } …

>> run(v1, v2, v3, v4); you are attempting to pass the variables by values instead of by reference (pointer). Put an ampersand & in front of each variable to make them pointers like this [inlinecode] run(&v1, &v2, &v3, &v4);[/inlinecode]

most win32 api functions have two versions -- one for char* and another for wchar_t*. If you are looking at a function that uses TCHAR* then you can just safely assume char* when not compiled for UNICODE.

actually that isn't even compileable C function. It needs braces around lines 3-6. And the loop starting at line 10 has several problems -- one of them is probably infinite loop at line 12 because the value of j may never get incremented. It is also a horribly written function. …

Opening a database is expensive in terms of both time and resources. So the fewer times you have to open it the better performace your program will achieve. I would opt for option #2. Of course one problem is that you may need to tell the database server to flush …
