Write a program, analogous to the Unix/Linux cat command, that uses mmap() and write() system calls (instead of read() or write() ) to copy a source file to the screen. Use fstat() to obtain the size of the input file which can be used to size the required memory mapping.

The statement to write the file contents to STDOUT is

write (STDOUT_FILENO, addr, sb.st_size);

where

addr is the start of the mapping, gotten from mmap() and,

sb.st_size is the size of the mapping returned by fstat() in the

sb struct.

Please show the command line to compile the file and run the code and the screenshots
