Review of C++
C++ is an object-oriented programming language. C++ was developed by Bjarne Stroustrup at AT&T Bell Laboratories in USA, in the early eighties. C++ is an extension of C. C++ is an incremented version of C. C++ is superset of C. The facilities like classes, function overloading, operator overloading are added in C++. The large programs can be built with C++.
Advantages of C++
C++ enhances C with classes, function and operator overloading, and polymorphism. It supports building object-oriented libraries, and most C programs can run on a C++ compiler. C++ programs are easy to implement, maintain, and expand.
Traditional procedural programming approach
- Emphasis is on doing things.
- Large programs are divided into smaller programs known as functions .
- Data move openly around the system from function to function.
- Employs top down approach in program design.
Tokens, Keywords and Identifiers
The smallest individual units in a program are known as tokens . C++ has following tokens. Keywords.
- Identifiers.
- Operators.
- Strings.
- Operators.
A C++ program is written using these tokens.
There are 48 C++ keywords. These keywords have specific meanings associated with them. These keywords cannot be used as variable names.
Identifiers refers to the names of variables, functions, arrays, classes
