Introduction

Constructing software always needs proper planning to bring the best out of the
product. The best way to do it is to go along with the Rapid Application
Development model, which includes analysis, design, build and test phases into a
series of short, iterative development cycles.

According to the requirement, the advanced scientific calculator was developed as
an MDI (Multiple Document Interface) model, with the use of the visual studio.

Visual Studio is an Integrated Development Environment (IDE) developed by
Microsoft to develop GUI (Graphical User Interface), console, Web applications, web
apps, mobile apps, cloud, and web services, etc. Since it is not a language-specific
IDE as we were able to use this to write code in C# to code. C# is a modern,
general-purpose, object-oriented programming language, which is designed for
Common Language Infrastructure (CLI), which consists of the executable code and
runtime environment that allows the use of various high-level languages on
different computer platforms and architectures. The output of the process will be
defined through this report.

Basic
Features

Our Modern Scientific Calculator has the capacity to perform the following tasks.

Standard - For general mathematical purposes.
Scientific - For advanced operations which involve trigonometric functions
and logarithms.
Temperature - For conversions among Celsius, Fahrenheit, and Kelvin.
Multiplication - To get the multiplication table of a given number.
Unit Converter - For conversions among Gram, Kilogram, and liter, milliliter
under the weight sector, as well as the conversions among kilometer, meter,
centimeter, Feet and inches under the length sector.

The way how the above forms are defined in C# will be elaborated on next
thoroughly.

Coding Process

The coding process was done by sharing the parts among the team. Altogether
there are 9 parts of coding merged together to build the calculator. The codes and
the output interfaces are represented below.

1 - Splash Screen

This is what represents the system name, version, and names with index numbers
of the group members.

The code:

Contribution

The process of writing the software itself involves the planning required for
developing the product. Therefore, it's a must to thoroughly analyze the
requirement in order to prepare a perfect plan to design the software. Then
the path is clear to build and test the required software. On that count, our
team gathered together via zoom platform and divided the main task into
sub-tasks to combine and construct a well-functioning advanced scientific
calculator. Here's how we did it.
