OK, so start by calculating the input ranges, then you can create scale factors to map the input range to the output range.

Do you want to?

- clip extreme values, say if ( x > 25 ) x = 25 ?
- scale the graph (max=100), so px = x * 25 / max

Short answer - don't mix cin and getline.
They don't play well together.
Plenty of past posts and answers for this problem, look around.

Pure dumb luck is all.

Your cout statement basically filled that part of the stack with a value which was harmless enough (maybe even the right answer).

Taking out the cout statement, that part...

smallest = PRIORITY[nc[0].row][nc[0].col];

for ( int i = 1; i < cnt; i++ )

If count is 1, bestindex is garbage.

There's a memory overwrite bug in your code somewhere (most likely anyway).

Without seeing the whole code, we're not going to figure anything out staring at those 3 lines.

Read the manual - it's good practice for the future.

Try
volatile int variable;

Even then, you should really use proper synchronisation.


If the compiler sees

int variable = 0;
while (variable == 0)

a) Your "cd" command only lasts as long as the sub-process does (and it only affects the sub-process). If you really want to change the directory in this process, you need to use the chdir() API...

pow (23, 2)
You're passing two integers.

File permissions are platform specific, so you only get access to them using platform specific APIs.

Taking a stab at guessing line 98

VoltageGain = double pow ((275 / sqrt (pow (23, 2) + 0.5 * pow (f, 2))), n);

What does double do here?

Paste your CODE, not some fuzzy bitmap image.
How the hell are we supposed to quote text from that?

Oh, and the for loop in your ctor is broke.

pipes are a POSIX API (and not a language issue at all).

If you've got an appropriate declaration, then you can call them from whatever language you like (perl and python can access pipes as well).

> actually i wonder how can i make header file with private and public data?
Yes, they're called classes.
Which is pretty much the root concept of C++ programming.
Time to read the book again.

Mmm, hidden process, visible .exe - I wonder what's going on here....

Look at some other forums as well

oh wait, you're already there, and making progress.
Why are you here as...

Add some debug code, check the good, bad, eof bits.

Does it work for small files?

Which OS/Compiler are you using?

Are all the lines in...

Look at all the pretty colours in your post.
Blue means it's a string - is it really meant to be a string?

Consider looking for the mis-placed "

Does

while (getline(sup,line)) temp << line << endl;

succeed in just copying the file?

If it does, then removing the first line is simply
getline(sup,line); // burn line 1
while...

So do it in stages, say the spaces up to and including the first hash.

You don't have to write the whole thing just to make progress.

Shouldn't the OP be looking for a C++ solution, rather than messing with archaic C-style functions and char arrays?

You're not passing references to them.

So inside the functions, changes are made on a local copy, which is lost when the function returns.

Well gmtime() does most of the donkey work for you.

> Here is the error... in german :x
Except that seems to suggest the problem is in a function called calc3() and not one called toDouble().

Did you fix it in all the places?

Posting new error...

They're class member functions, which means they need an object to be applied to.

Eg.

mat1.Add(mat1, mat2);

Of course, you might regard one of your parameters as now being redundant.

Why not?
Being good at s/w is being able to recognise the best tool for the job.

There's probably a dozen RFCs...

Wait, you want us to wade through a 700+ line haystack (which isn't even complete) looking for a needle which might not even be present in the subset you've posted?

Try using the debugger again.
...

int nrP = 6;
for ( i = 1 ; i < nrP ; i++ ) {
cout << i << " " << (2 * nrP - 2 * i - 1) << endl;
}

Notice anything about the sequence of numbers?

Are we sitting comfortably, then I shall begin.

Seems to me like a case of not using the right tools for the job.

Doing this as a browser plugin would be a snap (by comparison).

Starting where you are, you're basically saying "I need to use...

So use the debugger and put a breakpoint at the start of where you suspect the problem starts, and then wait for the first of the "first chance exceptions" to happen.

Then home in on the problem.

Is that
char *_filename;
or
char _filename[1000];

Or why are you messing with char arrays when there is a perfectly usable std::string which would have seen you finished hours ago.

Lessons in cause and effect.

Memory is allocated from one (or more) larger pools of memory.
