This article provides a comprehensive overview of C++ basic concepts along with easy to understand examples. Tokens Smallest indivisible parts of a program are called lexemes and groups of similar lexemes are called tokens. C++ program contains several items and those are identified as tokens by a compiler. C++ tokens are as follows: Keywords […]
This article provides a comprehensive overview of input and output in C++ programming language along with example programs. Any program in a given programming language needs significant amount of input from the user and also needs to display to the output several times. To support such I/O operations, C++ provides a library which contains […]
In this article we will look at introduction to C++. First we start with the history of C++ and move on to the basic structure of a C++ program. History of C++ C++ was developed by Bjarne Stroustrup in 1979 at AT&T Bell Labs. C++ is an object-oriented language which includes imperative as well […]
This article provides a comprehensive introduction to object oriented paradigm along with real-world examples. This world is made up off several objects and objects communicate with each other. Similar objects can be grouped together. For example, take a college. It can have two working sections like teaching and non-teaching. These two groups can be […]
