// Tasks:
// 1. compile without change --> *include* path error (and others)
// 2. fix include path error, i.e. adjust the project properties for C/C++ to
//    also use the local .\inc path for includes

// 3. compile and link --> *compiler* errors
// 4. fix all *compiler* errors, i.e. fix missing includes in main.c

// 4. compile and link --> *linker* errors
// 5. adjust the project properties for Linker to also link with the
//    library lib\read_write.lib

// 6. compile and link --> fix remaining errors if any


#include <stdint.h>
