El sistema de datos por herramientas es un software libre, libremente disponible para la realización de gráficos 3D por computadora, procesamiento de imagen y visualización. VTK consiste en una biblioteca de clases de C++ y varias capas de interfaz interpretadas como Tcl/Tk, Java, y Python.
"The Visualization Toolkit (VTK) is an open-source, cross-platform, software system for 3D computer graphics, image processing, and visualization. Originally written as companion software to the textbook The Visualization Toolkit: An Object-Oriented Approach to 3D Graphics by Will Schroeder, Ken Martin, and Bill Lorensen, VTK provided the motivation to found Kitware.
From initial development in 1993, VTK has grown to be the premier visualization system today through the support and dedication of a global community. Much of this work has stemmed from Kitware, recently including a transition to using Git and Gerrit for distributed version control; the addition of pointer classes to facilitate pointer management; enhancement of the VTK pipeline to suit AMR; improvements to the plotting and charting capabilities in VTK; and general toolkit maintenance."(http://www.kitware.com/opensource/vtk.html)

There are some cases where we create a function in our program destined to receive an special type of value. Here is where we want to ensure that the user enters the correct value and not any other type that will cause our program to crash, thats why we validate the user input by using some tools that I will show you.

"El análisis estudia los requisitos que debe de cumplir la aplicación. El resultado del análisis es una hoja de especificaciones en la que aparecen los requerimientos de la aplicación. Esta hoja es redactado por la persona responsable del proceso de creación de la aplicación. Si estás creando algoritmos o programas sencillos, el análisis consistirá en evaluar estos tres pasos fundamentales:
Si realizas estos pasos antes de comenzar a escribir código independientemente del lenguaje que uses, vas a realizar programas de calidad y vas a eliminar muchos errores que te pueden surgir si no analizas el programa y los requisitos que te piden del programa."(http://aprendecpp.com/blog/programacion-en-c-el-analisis.html#more-118 )

To open o create a file in C++, first you must be sure to add the proper library which is , as you can see, in my example the first command in main is "ofstream file", that's to create a file inside your program. Later I name it as Hello.txt, and in there you can put in whatever you want, I just typed in a line that said "Hello dudes", and that text file will remain with that line unless I erase it. After that you just close your file.

Inputs have to be validated before allowing any kind of processing or operations to be performed on it. This is extremely important because , an unhandled wrong input might have the complete ability to crash a system. C++ has some good validation techniques that can be used to validate most kind of inputs. This post discusses some of the techniques and its shortcomings and what could be done to improve the quality of validation.
Now, consider a program has to accept only integer inputs and reject all the others. So, the developer would have declared to store the integer value in say “int a;”. So “a” will store the input value.
When the user input is accepted using the “cin>>a” statement, we can use the inbuilt methods surrounding the “cin” statement to test its status.

La sintaxis de una matriz es C++ es la siguiente:
|
int matrix[rows][cols]; |
En este ejemplo int es el tipo de dato, matrix es el nombre del todo el conjunto de datos y debo de especificar el numero de filas (rows) y columnas (cols).
Las matrices también pueden ser de distintos tipos de datos como char, float, double, etc. Las matrices en C++ se almacenan al igual que los vectores en posiciones consecutivas de memoria.
Podriamos imaginarnos que una matriz es como un tablero, pero en realidad el manejo es como su definición lo indica, un vector de vectores, es decir, los vectores están uno detrás del otro juntos.
Para acceder a los elementos de la matriz es utilizando su nombre e indicando los 2 subíndices que van en los corchetes.
Si coloco int matriz[2][3] = 10; estoy asignando al cuarto elemento de la tercera fila el valor 10.
Es importante tener en cuenta que tanto filas como columnas se enumeran a partir de 0.

This string is actually a one-dimensional array of characters which is terminated by a null character ''. Thus a null-terminated string contains the characters that comprise the string followed by a null.
