This is my code in file processing. the requirement is to create a C program that will store patients' personal and vaccination information to a file with the name Vaxx.txt, Import/Read a file and append it to Vaxx.txt, then display all records in Vaxx.txt before exiting the program. And I have a problem with importFile function, the importFile function has to read the file and append all of its content to Vaxx.txt.
