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

two integers is confusing....

A variety of combinations involving floating point types...

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?

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).

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.

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

Notice anything about the sequence of numbers?

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.

Lessons in cause and effect.

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

int main ( ) {
int *p = new int[10];
for ( int i = 0 ; i <= 10 ; i++ ) p[i] = 0; //...

Doubtful - it won't compile with TurboCrap, and it wasn't posted with code tags.

Lemme get this straight, you wrote some code but you don't have a really good idea of how it's "SUPPOSED" to work?

This is basically voodoo programming; write some mystic runes, sacrifice a goat,...

Congratulations.

But using code tags would have been a good idea, if you wanted people to read it.

Not enough?
How about looking at your needlessly complicated push_back()?

Your code is wrong.

You read a line
You validate a line
If the line isn't what the user was asked to provide, then print an error message and read again.

Read the link (or your book). Your syntax is broken.

Is there a particular reason why you're doing this the hard way, with a "roll your own" per-character input?

Because there are standard library functions to read a whole line for you.

Either set the length of the vector before you start, or use push_back() to add each new cube as you go.

Read this, make an effort, post that attempt and then ask a specific question.

Don't just dump your assignment on us and then go party, hoping...

delete &capacidad;
delete &indice;
delete &datos;

All these are wrong.
a) you don't call delete AT ALL unless you called new.
b) a new [] is matched by a delete []
So
delete [ ] datos;

All the files are in the same directory?

If so, all you need to do is add the two .cpp files to some kind of project (or makefile), and then build.

It lacks imagination, but did you try this?

What - that you can't use a float to subscript an array?

The error message should have been pretty obvious.

Array subscripts are integers.

Languages like C and C++ are far too flexible to diagnose ALL possible run-time faults at compile time.

If you post an exact run-time error message, we might be able to tell you where to start...

Dunno, I can't see your code from here.
It would work if you did everything right, but since it doesn't, I'm guessing you need to fix something.

You've got

#include "somethingElse.h"
#include "DoTestData.h"

The last thing in somethingElse.h is the real cause of the problem, and it will be missing the ; in question.

Or just be more careful writing out the existing data....

Your struct contains strings.

These are not simple objects, they contain pointers to where the data is stored (elsewhere). Simple write() functions don't know this.
...

Better yet, tell US what you found out, how you solved it and then mark it closed.
Give something back.

> file.write(tit,30);
If you're going to write 30 bytes, then you need
char tit[30] = "Title";

otherwise you're reading uninitialised memory and storing up who knows what kind of trouble.

> My requirement is that I add a very small value of the order 10^-7 with a relatively big value, say 36.63
floats have about 6 decimal digits of precision, doubles about 15.
10^-7 is more than 6...

Correct indentation, and proper use of { } in all the places you need them would help.

Debug assertions usually show up when you fail to do proper error checking.

Eg.

FILE *fp = fopen( "missing_file.txt", "r" );
// no check for success
int ch = fgetc( fp ); // debug assert here

I've no idea then.

Did you start with an empty Win32 console project?

Read the intro threads on how to use code tags.

It's a pretty sure thing that you're looking at the effect rather than the cause.

Something else is probably trashing memory. Here is just where you first notice there is a problem.

Try turning PCH off.
It's only relevant if you're compiling vast projects which are pretty stable.
