If you want to delete those lines from the file itself then you have to rewrite it. First open that file for reading, then open another temporary file for writing (name it anything you want except don't give it the same name as the original). After that, code a loop …

>>function takes 0 arguments What line number? Pay close attention to the parameters of the function prototypes at the top of the program and the parameters (or lack of parameters) passed in lines 44 thru 50 of your program.

Without knowing the values of the variables its quite impossible to determine the solution to your problem. What compiler and os are you using? You need to learn how to use your compiler's debugger so that you can single-step through the program execution and see that the variable's values are.

The function should be declared to return [b]bool[/b]. If the value is even then return true otherwise return false.

program A calls program B. Program B writes some stuff to a file and program A reads it. Or you could use pipes (see man pages for [b]popen()[/b] )

Non-privileged mode operating systems are probably just too small to accommidate all the code needed to protect the hardware from damaging programs. For example MS-DOS 6.X and earlier were already limited to using 640K of memory, and that had to include the operating system and all TSRs, which left most …

I did not get any errors with the code you posted. What compiler and os are you using? line 35: never ever use [b]gets()[/b] for anything because it can corrupt the memory of your program. If you type something that is longer than the destination buffer can hold, [b]gets()[/b] will …

>> am not able to do that Yup -- you found out the hard way that it can't be done. One solution is to write the variables to a file or shared memory so that other programs can read them.

Not possible to do it in pure C or c++ because the languages do not support cursor movement. You could do it in MS-DOS pretty easily with TurboC++ compiler. All modern MS-Windows compilers will require win32 api [URL="http://msdn2.microsoft.com/en-us/library/ms682073.aspx"]console functions[/URL].

Interesting article about the Flat Earth Society. I'll bet they are also creationists who believe the earth is only 6,000 years old. Both turn a blind eye to scientific fact. As for 9/11 -- my bet is that Bugs Bunny and Daffy Duck were behind it. They probably hired the …

even the fstream example you posted is not workable. line 4 does not calculate the size of a file but the number of TCHARs in the file, which might or might not be the same as the size depending on the UNICODE setting. As for CFile, the answer is NO …

why isn't it free ?

One huge problem is pointer [b]b[/b] only points to a one-byte empty string which can not be expanded. Since you want a string of 8 characters then you have to allocate memory for it something like this [icode]char b[9] = {0};[/icode]. That will allocate memory for 8 characters plus a …

What kind of an object is ListViewTextItem? The second argument to fprintf() is a char*, not a c++ class. fprintf() doesn't know a thing about c++ or objects.

My guess is that you need to add a constructor which initialized all the pointers to NULL. As it is those pointers are uninitialized and point to some random place in memory and any linked list using them will fail

You mean remove it from CPlanet? or leave it there and instantiate another instance of it in main(). I assume the purpose of CAnimation is to make the class rotate on its axis, so removing it from CPlanet would not be a very good idea. If you instantiated an instance …

That's what happens when you jump the gun and dive right into the middle of a program. Its sort of like trying to fly a 747 jet airplain after about 4 hours flying time in a Cessna twin engine prop. You might learn to fly it after crash landing several …

line 30 of the header file needs a semicolon

>>fgets( str[y], sizeof str[y] / sizeof ( char ), stdin ); The division is unnecessary because sizeof(char) is guarenteed to always be 1. So it can be reduced to this: [icode]fgets( str[y], sizeof str[y], stdin );[/icode].

You will want to create a file with *.c extension and VC will compile it as a c file, not c++. Create a new empty project. Then add a new file, when you give it a file name also specify the *.c extension -- such as myfile.c. How you do …

1. getScore() is supposed to return a double, but is actually returning a float. If you want it to return a double then declare [b]avg[/b] as a double. 2. The calculation is doing integer arithmetic because 3 is an integer. If you want it to do floating point then it …

I thik below is the correct implentation of that class. One problem with this implementation is that the class is attempting to manage a list of objects that it does not own, and if some other function decides to delete one of the objects it will invalidate the pointer in …

I suppose that [b]something[/b] is either Sleep() (MS-Windows) or sleep() (*nix) which will cause your program to get very little CPU time.

I think its pretty funny. :) :) Some people just like to be silly and laughed at. You all are too prudish. Of course, on the flip side of that coin it means he will never be taken seriously on any of the sofware development boards.

your examples are kind of screwy but I think I know what you want. There are two ways it could be done -- either as an array or a pointer to the data. The difference between the two is how you want to access the data in func2() -- use …

Instead of making 8 copies of that huge array I'd make just two, say array A and B. pass array A to a sort method, after sorted copy B to A and pass A to the second method. Do this for each sort algorithm. It'll save a whole lot of …

First, the program you posted is a bastardization of C and C++ languages. As for your problem you need to flush the '\n' (Enter key) from the keyboard buffer after the sscanf(). There are several ways to do that but in C the easiest is to call getc() to remove …

>>Where do c++ developers obtain their libraries learn to use google. It would seem to me that you may have to write a device driver or program that hooks into the keyboard device driver because normally keyboard input is normally routed to the foreground window.

A more important question is: why is that [b]find[/b] method returning void? A find method normally locates an instance of something and returns the result to the calling function. If it didn't there would be no point to the function as it appears to be with your function.

Learn to format your code better so that you can see what you're doing. Only takes a couple seconds to hit that space bar.

I don't use *nix but it sounds like a memory leak if there are only a few threads running at the same time. Could also be a limitation of the max number of open sockets at the same time.
