title: CRUD Add/delete/edit/ search / display program
body: <p>I have a group project and my role is to make add function to add data permanently to a file, and I have to use dynamic arrays and pointers and I understand what they do but I don't know when to use them so if someone know a video that helps me I would appreciate it or if you can help me on how to begin I would also appreciate it (note : I know how to make file by fstream my problem is using the dynamic arrays and pointers as I don't know where to use them and I have to open a file at the beginning to read from and then save the data on the dynamic arrays with the old data in the old file to a new file at the end of the program)</p>
