Introduction to C++
- C++ programming language developed by AT&T Bell Laboratories in 1979 by Bjarne Stroustrup. C++ is fully based on Object Oriented Technology i.e. C++ is ultimate paradigm for the modeling of information.
- C++ is the successor of C language.
- It is a case sensitive language.
Object Oriented Programming follows bottom up approach in program design and emphasizes on safety and security of data.
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.
