12th Class Chapter No 2 - Object Oriented Programming in C++ in Computers for CBSE NCERT

A Data file is a computer file which stores data to be used by a computer applicationor system. It generally does not refer to files that contain instructions or code to be executed (typically called program files), or to files which define the operation or structure of an application or system (which include configuration files, etc.); but specifically to information used as input, or written as output by some other software program. This is especially helpful when debugging a program.
a pointer is a programming language object, whose value refers to (or "points to") another value stored elsewhere in the computer memory using its memory address. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the pointer.
