Learning Objectives $$ Design and implement programs in a Unix environment that open, close, read, and write files. $$ Demonstrate an understanding of the Unix file system by changing file permissions to allow programs to open, close, read, and write files. $$ Design and implement a program that uses pointers and dynamic memory allocation and deallocation. $$ Use valgrind to find memory leaks in programs. Implement programs that use dynamic memory allocation and deallocation and have no memory leaks. $$ Use GDB to debug programs. Problem $/$ Exercise The goal of this project is to give you system programming experience with four file I$/$O system calls $($open$,$ close, read, and write$),$ UNIX file permissions, and dynamic memory allocation and deallocation in C$.$ In this project, you will implement a C program that reads in the contents of two input files. The program will then compare the two files, byte$-$by$-$byte, write differences into two output files, and output timings for the program$$s two main steps as stated in the project$$s requirements.
