The branch of engineering associated with software development and testing of products and services is called software engineering. Well defined principles and procedures are used in software development that results in an efficient product. This tutorial includes the basic understanding of software design, product life cycle, and maintenance. Software consists of interconnected programs and the codes are written by developers in any of the programming language. Engineering involves the knowledge to invent, design, build and maintain the software products evolved from the process. Software engineering helps to manage the dynamic nature of the software used in the process.
In order to run the program ‘Hello World’ identify the approach first and then solves the problem. ‘Hello World’ can be written through echo command or through any text editor. If echo command is used, simply print ‘Hello World’ in one line and the problem is solved.
The tutorial is intended for people who know at least one programming language and wish to pursue their career in the field of software. Also, students who are learning software engineering, development can follow this tutorial to improve their knowledge.
