And what if it is standard output? How do I specify "cout" to be binary?

Hi,

I´ve made a program which should output som binary data. The problem is that more bytes than I specify gets out, and somehow the data seems a little corrupt. It´s only a problem under Windows,...

Haven´t quite read your code, but, you don´t mention what is your problem. Compiler errors? Malfunctions? What?

I´d like to read in some bytes from a file, but first I need to know the file size. How does one do that in C++?

Just found the serious bug.

Í used logical AND instead of bitwise AND. Resulted in every byte converted to 1...

Thanks, that solved one bug.

The program, though, still doesn´t work correctly. Anymore suggestions?

Hi,

I´m trying to write a program that does some color conversion, but I cannot get it to work right. It seem that that the compiler doesn´t like conversion between int and double. Here´s the...

Guess you shouldn´t be making statements in class declaration:



pointer=&h;


Do this in your constructor instead!

Thanks! That solved all my problems.

No, my friend, using & passes it as reference.
Using * passes it as pointer.

Try out this piece of code yourself:



#include <iostream>
using namespace std;

When called, it passes the values, when returning it passes the values!

It´s like this:



function(type passedbyvalue,type& passedbyreference);


The passedbyreference variable shouldn´t...

That helped! But - yeah - I´m getting a byte too much... Do you know why, cause I can´t understand this one as well....

It´s difficult to say. I can´t see anything wrong in your code, but nethier can I see anything usefull...

Should that be like:



in.open(argv[1],ifstream::in|ios::binary);


Or how should I specify it?

Another things is - it´s not just a few bytes short, but it depends much on the file...

Sure! It´s a program which calculates the entropy of a source. The entropy is a statistic measure, and the calculations are working like they should. The problem is, that when run on window -...

Use your defines!

You have defined TABLE_SIZE but you don´t use it. Do yourself the favor!
Also define like:


#define MAXLINESIZE 256


and replace your magic 256-number with that.

>>>while(in.good()){
>>>data[i++]=in.get(); }
>This is a buffer overflow just waiting to happen.

I know that, but right now it´s only in test phase, I´ll adjust that later.

Hi,

I´ve written this program to input some data, and make some calculation on this data. Problem is that I cannot get the input working. I´ve copied the code from another program of mine where...

Is it possible to assign a double to NaN in c++ like:



double number = NaN;


Suggestions welcome...

You seem to know pretty much what you wanna do. Here´s my advice:

1. Write pseudo
2. Convert to C++
3. Compile and Run
4. Find errors, and if you can´t, then come back here and ask!

Specific...

Does anyone know how to check for overflow in a c program?

like when:



result=var1+var2;


How do I know if an overflow has occured?

Sure I could read the thing into a string, but what I search is a function that will FLUSH unread input. I thought clear(): did that, but it doesn´t... Any suggestions?

Hi!

I´m trying to fulsh standard input - all though this seems not possible to me. My code is:



bool exit_status;
char current;

exit_status=false;

Some compiler support differen´t syntax for main. Check your compiler documentation - maybe you´ll find one which suits you better...

Just got it working!

I needed to write like this:


private:
istream& is;
