IN c++/C Unix:

Program should make two folders(folder1 and folder2), one file(file3) and a symbolic link(link4) in the a4part1 directory.

Folder1 should have a file(file1.txt) and folder2 should have another file(file2.txt) ALSO THE LINK IN A4PART1 DIR SHOULD REFER TO FILE2.TXT.

Do not use system() function call in your program.

Write a C/C++ program (a4part1.c) to create a few directories as shown below in your current directory, a few files, and a symbolic-link link1.

You should use some of the following system functions .

open, openat, creat, open, lseek, read, write.

stat, fstat, fstatat, lstat, access, faccessat, umask, chmod, fchmod, fchmodat, chown, fchown, fchownat, lchown, link, linkat, unlink, unlinkat, remove, rename, renameat, symlink, symlinkat, mkdir, mkdirat, rmdir, chdir, fchdir, getcwd

For example, to change current directory, you should use chdir( ) function to change the directory. You should use creat() function to create each file.

First (1), your C program will create a directory (a4part1) for this assignment, and then create the files and directories as shown below, using C function call(s), recursively (that is, in depth-first order and left to right). That is, folder1 will be created first, then file1, and so on. You should create link1 (a softlink to file2) after file3 is created.

Second (2), you type the command ("ls R") to get the listing of all the directories and files in a4part1 directory.
