Experience. FILE *fp1, *fp2; While doing file handling we often use FILE for declaring the pointer in order to point to the file we want to read from or to write on. File Pointer: A file pointer is a pointer to a structure, which contains information about the file, including its name, current position of the file, whether the file is being read or written, and whether errors or end of the file have occurred.
