PLEASE Help with long increment

[korbenjr]

Hi people!

I'm starting programming in C++. I thought it would be easy because I have some experience with Java, but it is not so, really.

I'm completely confused about an increment of a variable in a function of one class of my program.
Here's the code:

This is the .hh file, where I declare the private variables:

long mostras;
double sumX;
double sumX2;

Here I declare a variable of type "long", which I want to increment everytime I call to a function in the class.

In the constructor of the class (.cc file) I say:

mostras = 0;

And then, in another funcion of the class (.cc file) I say:

 mostras++;                         // Increment of the variable "mostras"
  cout<<"samples computed: "<<mostras;

When I run the program:

samples constructor = 0
samples computed = 1056964609

I can't understand why it jumps from 0 to 10569646!!!
I incremented it only once and I am not modifying this variable in any other lines!!!

I'm sure this is an stupid thing, what I'm doing, but if anybody could help me...

thanks a lot.

You're going to have to post your code if you want an answer. I can't diagnose the problem from what you've posted so far.
