C Tutorial

C Introduction
C is a high-level structured oriented programming language, used in general purpose programming, developed by Dennis Ritchie at AT&T Bell labs, USA between 1969 and 1973.

Some Facts About C Programming Language
In 1988, the American National Standards Institute (ANSI) has formalized the C language.
C was invented to write UNIX operating system.
C is a successor of ‘Basic Combined Programming Language’ (BCPL) called B language.
Linux OS, PHP and MySQL is written in C.
C has been written in assembly language.
Uses of C Programming Language
In the beginning C was used for developing system applications e.g. :

Database Systems
Language Interpreters
Compilers and Assemblers
Operating Systems
Network Drivers
Word Processors
C has Become Very Popular for Various Reasons
One of the early programming languages.
Still the best programming language to learn quickly.
C language is reliable, simple and easy to use.
C language is a structured language.
Modern programming concepts are based on C.
It can be compiled on a variety of computer platforms.
Universities preferred to add C programming in their courseware.
Features of C Programming Language
C is a robust language with rich set of built-in functions and operators.
Programs written in C are efficient and fast.
C is highly portable, programs once written in C can be run on another machines with minor or no modification.
C is basically a collection of C library functions, we can also create our own function and add it to the C library.
C is easily extensible.
Advantages of C
C is the building block for many other programming languages.
Programs written in C are highly portable.
Several standard functions are there (like in-built) that can be used to develop programs.
C programs are basically collections of C library functions, and it’s also easy to add own functions in to the C library.
The modular structure makes code debugging, maintenance and testing easier.
Disadvantages of C
C does not provide Object Oriented Programming (OOP) concepts.
There is no concepts of Namespace in C.
C does not provide binding or wrapping up of data in a single unit.

C does not provide Constructor and Destructor.

Python Lists

Python Lists Dealing with data in a structured format is quiet generous, and this is possible if those data are set accordingly in a specific manner. So, Python provides these data structures named ‘lists’ and ‘tuples’ that are used to organize data in  single set. Python has 6 built-in sequences and among them the most famous are “lists and tuples”. The lists are containers that hold a number of other objects in a given order. It usually puts into practice the sequence protocol and allows programmers to add or remove objects from that sequence. Each element of the sequence is assigned a number i.e. he index and the first index is 0 (zero). This versatile data-type of Python is written in a sequence of list separated by commas between expressions. Creating Lists To build a list, just put a number of expressions in square brackets. The syntax is: Syntax: lst1 = [ ] # lst1 is the name of the list lst2 = [ expression1 , …. , expression_N ] Example: #!/usr/bin/python ls...

C++ Objects and Classes

C++ Object Oriented C++ Objects and Classes In object-oriented programming languages like C++, the data and functions (procedures to manipulate the data) are bundled together as a self-contained unit called an object. A class is an extended concept similar to that of structure in C programming language; this class describes the data properties alone. In C++ programming language, class describes both the properties (data) and behaviors (functions) of objects. Classes are not objects, but they are used to instantiate objects. What is a class? A class is an abstract data type similar to ‘ C structure ‘. Class representation of objects and the sets of operations that can be applied to such objects. Class consists of Data members and methods. Primary purpose of a class is to held data/information. This is achieved with attributes which is also know as data members. The member functions determine the behavior of the class i.e. provide definition for supporting various operations on data held...

Java Method Overriding

Java Method Overriding Declaring a method in the subclass which already exists there in the parent class is known as method overriding. When a class is inheriting a method from a superclass of its own, then there is an option of overriding the method provided it is not declared as final. The advantage of using overriding is the ability to classify a behavior that’s specific to the child class and the child class can implement a parent class method based on its necessity. There are certain rules that a programmer should follow in order to implement overriding. These are: In Java, a method can only be written in the child class and not in same class. Argument list should be exactly the same as that of the overridden method of that class. Instance methods can also be overridden if they are inherited by the child class. A constructor cannot be overridden. Final – declared methods cannot be overridden. Any method that is static cannot be used to override. The return type must have to be the...
