General Instructions: - For this assignment, you must use C99 language syntax. Your code must compile using make without errors. You will be provided with a Makefile and instructions on using it. - Test your program thoroughly with the GCC compiler (version 5.4.0) in a Linux environment. - If your code does not compile, then you will score zero. Therefore, ensure you have removed all syntax errors from your code. Write a C program (directory.c) to perform various operations on directories and associated system functions. Directories are frequently used in daily life to organize files in a well-structured manner. This program would use various system calls that are available in C programming to perform the operations. The program should perform the following directory operations: - Creating a directory - Removing a directory - Getting the current working directory - Changing a directory (to one level up from the current directory) - Reading a directory - Closing a directory, the current directory The program should present the user with a list of options to select the directory operation and keep looping until the user enters " q " on the keyboard. You can use the makefile to compile and run the program. The expected output for executing make runq1 or. /directory is: - vscode /W23/CP386/Assignments/A01_W23 $./ directory Select the option(s) appropriately by entering the number: Enter 1 for creating a directory Enter 2 for removing directory Enter 3 for printing working directory Enter 4 for changing directory one level up Enter 5 for reading the contents of directory Enter 6 for closing the current directory Enter q to exit the program 1 Enter the Directory name you want to create: test Directory is Created Successfully.
