A file pointer is an opaque object that refers to a file. Opaque means that you should not attempt to delve into its specific value, other than to use it as a file pointer. FILE *fp; /* fp is the file pointer */ fp = fopen("somefile.txt"); if (fp == NULL) ...{exception}... fprintf(fp, "Hello somefile.txt"); fclose(fp);
Header file is a file which is meant to be included into another file during compilation. Examples: string.h, stdio.h, inttypes.h. Header pointer is a pointer to an object called header (for example header of a linked list).
The function ftell returns the position of the file pointer for a file.

Call functions fread, then function fseek, then function fwrite.
Your process' file pointer has nothing to do with the other process' file pointer.

File
There are two file types in C++ namely, text file and binary file. In text file EOF or end of file is represented by an end of file character having ASCII 26. In binary files EOF or end of file is represented by NULL in the file pointer
Yes, passing a variable by reference gives you a pointer to the original variable, meaning you can change its value from within the function being called and the change will affect the original variable.
Put the cursor (pointer) over the file and click once.
