What is structured programming paradigm | Razsoft education

 Structured programming                 Structured programming is a programming paradigm in which we use some predefine keywords to control the flow (branching) of the program. Unlike in procedural language we have goto keyword to control flow. In structured program we have for, while, do while if , else, these type of keywords to control the flow better and also have blocks to maintain the scope of the variable or to group a set of related code. These blocks are formed by curly braces ( { } ) in C++.

"climits" Header file in c++ programming language | Razsoft Education

 <climits> header file climits is a header file borrowed from c programing language limit.h header file. The header file is used to know the maximum and minimum value an integer data type can hold. The header file is implemented in C++ in standard namespace.  Here is the explanation of Macros used in climits header file char type :     CHAR_BIT - The macro represent number of bit in a  character.     CHAR_MIN -  For the minimum value a char can hold.      CHAR_MAX -  For the maximum value a char can hold.        CHAR_MIN -  For the minimum value a char can hold.     S CHAR_MIN -  For the minimum value a signed char can hold.     S CHAR_MAX -  For the maximum value a char can hold.     UCHAR_MAX - For the minimum value of unsigned char. short type :     SHRT_MIN - For the minimum value a short can hold.      SHRT_MAX - For the maximu...

What is C++? | Razsoft education

 What is C++ ?    C++ is a powerful high level computer programming language developed by Bjarne Stroustrup in 1979 at AT & T Bell’s lab . The language continue the legacy of C language to produce fast , efficient, reliable and portable code, But extended features for Object oriented programming and generic programming . So, programmers can write complex and large program easily but produce code as efficient as C does.

Drawing shapes using java graphics API | Razsoft Education

Image
Shapes in java  To draw shape in java, It provides shape interface. Any class that implement the shape interface will be used to draw shapes. To draw shapes we need to pass object of the class which implements the shape interface in the draw() of fill() method of graphics object. Outline of shape is known as path.      Java has already a list of class that implement the Shape interface to draw some basic geometrical shapes. Which is defined in to two main category Rectangular shape and non Rectangular shape. We can also implement shape interface in our own class to create custom shapes.   Rectangular Shape  Rectangular shapes are those shape which Extends the RectangularShape class. The class doesn't define any geometrical shape but it provide a rectangular frame to all the class that extend it. Here is list of some class that extends the RectengularShape class                      ...

Graphics2D API an introduction to Java2D | Razsoft Education

Image
            To overcome problems with the Graphics class and to enhance some functionality. Java introduces new class called Graphics2D . Which allows to better control over graphics operations? Also java introduces a whole set of package to do 2D graphics operation including image manipulation , drawing and transformation and the package is backward compatible.                For example Java2D API has separate class for each type of basic shapes. All the shapes implements Shape interface . Also we can define our own shape by implementing shape interface in our own custom shape class.                Control the fill and line style with control on width of the line. The Stroke and Paint interface was introduced to make custom fill and drawing style.         ...

What is Object Oriented Programming | Razsoft Education

 Object Oriented Programming : Object Oriented Programming (OOP’s) is a modern programming approach in which program is thinks as of set of objects communicates to each other to get a work done. Like in real life we have multiple objects that depend on each other for get a work done.             So, the idea was to design a data that has data and function that perform operation on that data. In C++ classes are the special data type that contains data called data member and function that perform operation on that data called member function. An object is instance of class.   Also Read about :    What is procedural programming paradigm ?   What is Structured programming paradigm ?

Different data types in C++ | Razsoft Education

 Data types in C++ : As we know computer is a data oriented machine so, to work with data it need to store that different programming language handles it differently. But C++ programming language provide us more control on data. A data type is to tell the compiler that how much memory a variable or constant going to take and what is type of data stored inside them. There are mainly two types of data group in C++. Fundamental data types :   They are built in data type provided by C++ programming language to work with simple form of data like integer, floating points and characters inside the program. Compound data types :   They are not built in C++. Where as programmer's define them itself when ever needed according to their use. They are defined with the use of fundamental data types, So, it's often refer as user define data type of derived data type. For example array, class, structures, etc. Learn more about  Fundamental data types :     1. Integers ...

Computer graphics an introduction | Razsoft education

Computer graphics or CG Definition: Computer graphics is a field of computer science in which we study the creation and manipulation of images.   Computer graphics is an art of communicating to computer visually. Application: Movies: -  In movies they use VFX to create many scene like large explosion, plane crash or create entirely new environment like in Avengers and avatar. Cartoons: -  It’s used to create fictional characters and animate them to make animation videos like Doremon, Tom and Jerry and Motu-Patlu.   Video games: -  Video game is industry completely based on computer graphics. It’s used to create environment, character and interaction with them. Some popular computer games are like Vice city, Temple run, PUBG, etc. Simulation: -  Using computer we can describe behavior of object’s in computer then simulate  them in virtual environment to see the effect. It’s also used to teach people about complex machine operation like p...
