Should be done using C. I have experience in Java but no experence in C, and this is hould be done by using the basics of C (including pointer). Please explain how to do this exercise in the comment beside each imporant steps / code.

DESCRIPTION: In this assignment, you will gain hands-oin experience with the C programming language. While you are not required to be a C expert to complete the work, you will certainly have the opportunity to explore most of the things that we have discussed in class (and a few other things as well) PROGRAMMING LANGUAGE In terms of your task, it is fairly easy to describe. You will be writing a simple search and replace application. Specifically, your job is to (1) find a user-specified text string within a group of disk files, (2) modify those strings and update the original disk files, and then (3) provide a report that indicates what has been done. It will work as follows: 1. The application will take a single command argument. This argument will be interpreted as a text string. For example, if your program was called replace.exe, you might enter replace.exe apple. Note that if you are using the Eclipse C/C++ plugin as your IDE, you can use a "Run Configuration" to specify the command line argument 2. You will then open each of the files in the current directory. If vou haven't done much programming with files and directories, it isn't especially difficult. That said the facilities for doing so in C are somewhat more primitive than those in languages such as Java. First, you will want to make use of the functions associated with . As we discussed in class, these are the basic IO functions, and can be applied not only to the screen and keyboard, but to disk files as well (There are countless online examples of basic C I/O). Here, you will use functions for opening and closing files, reading and writing bytes/chars to and from files, and for checking to see to see if vou have reached the end of the file 3. In addition to opening and reading files, you must also be able to read the contents of the directory in order to see what files need to be checked (the current directory "). Basically, a directory is just a special type of file that contains a list of the files within it. So the idea is to just loop through the file list, and open and examine each text file (for simplicity, all files used during testing will be text files with a .txt
