#ifndef AIRCRAFT_PERFORMANCE_H
#define AIRCRAFT_PERFORMANCE_H

// Purpose of header files: Header files are used to share functions and
//      variables between multiple files. The header file is included in the
//      file that needs the functions and variables. The header file is not
//      compiled by itself. It is compiled when it is included in another file.


//NOTES: #ifndef AIRCRAFT_PERFORMANCE_H: This line checks if AIRCRAFT_PERFORMANCE
//      is defined. If it is not defined, then the code between the #ifndef and
//      #endif is compiled. If it is defined, then the code is not compiled.

//      #define AIRCRAFT_PERFORMANCE_H: This line defines AIRCRAFT_PERFORMANCE_H
//      so that the next time the #ifndef AIRCRAFT_PERFORMANCE_H is called, it
//      will be defined and the code between the #ifndef and #endif will not be
//      compiled.
