Advanced Operating System

 Write a C or C++ program to run on a Unix platform. This program get catch three topics. The highest topic get be the footpathdesignate of a directory on the scheme.

Stat scheme overcome: int stat (const char *path, struct stat *sb) Once you own the designate of an register, you can use the stat scheme overcome to get past notification environing it. stat office catchs two topics, the highest is a footfootcourse designate and prevent is a pointer to struct stat, which contains notification environing the refine.

 Guidelines and Requirements 

 1. You can use either C or C++ for this programming enactment. 

2. Your program should run on a UNIX platform 

3. Add comments (environing the office/variable/class) to your method as greatly as possible
