Question

I need to complete tSubinfo and tSectionInfo in data.h in order to be able to save the following info:

In tSubInfo

id : That isthe identifier of the subseccion ( only one character)

subBooks: Vectors that tells us the position where books are in the subsection

totSubBooks: total quantity of books in the subsection

tSectionInfo:

section: Estructure of the type section

secSubs:Vector with all subsections (type tSubInfo) of the section (max 10 sections) which have one book

totSecSubs: total quantity of subsections in the Section

totSecBooks: total quantity of books in the section.

The code needs to go in data.h after /******************** code *********************/

Answer 1

note: i posted data.h and did according to your requirements

/* Uncomment the practice version you want to run */
#define SIMPLE_VERSION
//#define COMPLETE_VERSION

/* This code ensures that this file is included only once */
#ifndef __DATA_H
#define __DATA_H
/* If the constant DATA_H is not defined (ifndef), the code is added, otherwise, this code is excluded. When the code is added, the constant is defined, therefore next time this file will be included it will be defined and no inclusion will be done. */
