Introduction to C Sharp (C#) Language- From Coding to Reality

Introduction

C# The programming language by Microsoft is usually pronounced as "C Sharp". This object-oriented programming language runs on the .Net Framework. C# is a descendant of the C family and has links to C++ and Java. These two are also popular programming languages. C# 11 is the most recent version in November 2022. But its initial version was released in 2002.

The below post is all about C#. Gain more knowledge as you dive into the concept of C# language.

Why Use C Sharp (C#)?

C sharp language is useful for the following reasons:
 

• This popular programming language is simple to learn and use.
• C# is an object-oriented language that provides applications with a distinct structure. Moreover, it permits code reuse, reducing development expenses.
• Programmers can easily convert from C to C# or vice versa. This is because C# is related to C, C++, and Java.
• It enjoys strong community backing.

C# Applications

The C# programming allows us to create various safe and reliable applications:
 

• Window applications
• Mobile applications
• Desktop applications
• Web sites
• Games
• VR
• Distributed applications
• Web service applications
• Database applications 

Data Types in C Sharp Language

There are many commonly used data types in C#:

int

The term "integer" means figures without any fractional or decimal sections.

byte

The term " byte" also applies to integral numbers, but their range is much less (0–255).

float 

Float is a term for floating point numbers that are decimal.

double

Although double is a floating point number, it has a greater range of possible values.

character

The single Unicode characters 'L', '%', '@', and 'b' are stored in a file. This file is called a char, which stands for character.

decimal

Unlike float and double, decimal has a shorter range. But still, it stores decimal numbers.

bool 

bool stands for boolean that can only hold two values only. The values can be true or false. It is common in control flow statements. 

C# Framework

When you refer to the "C# Framework," you might be referring to the .NET Framework or one of its variations, such as .NET Core or .NET 5 and later. The .NET Framework provides a runtime environment and a selection of libraries for building and running applications. It provides a rich class library that includes pre-built functions and components to help developers build various types of applications more efficiently. The framework also covers many programming languages, including C#.

Two important components make up the basic architecture of the .NET Framework:

Common Language Runtime (CLR)

It manages any code (written in a.NET compatible language) during execution. The CLR loads the necessary libraries and converts the code into machine code. Further, the computer's processor uses it while running an application.

.NET Framework Class Library (FCL)

The FCL offers a sizable collection of pre-built classes and functions. They are useful to build a variety of applications.

How to make Choices and Decisions in C Sharp Programming language?

Condition Statements

Normally, control flow statements assess a condition statement. Further, the program will proceed accordingly depending on whether it meets the criteria. There are more comparison operators that you may use in condition statements. They are more than determining whether two values are equal. Such as:
 

• Greater than (>)

It will return 'true' if the left is greater than the right.

6 > 2 is true

4> 7 is false
 

• Smaller than (<)

It will return 'true' if the left is smaller than the right.

3 < 8 is true

8 < 4 is false
 

• Not equal (!=)

It will return 'true' if the left is not equal to the right.

4 != 3 is true

8 != 8 is false
 

• Smaller than or equal to (<=)

It will return' true' if the left is smaller than or equal to the right.

5 <= 5 is true

6 <= 4 is false
 

• Greater than or equal to (>=)

It will return 'true' if the left is greater than or equal to the right.

4 >= 4 is true

6 >= 7 is false

There are also three logical operators in the C sharp programming language. These are &&, ||, !, and they are useful to combine multiple conditions.

Control Flow Statements

Now you are familiar with condition statements. The next step is how to use them to regulate a program's flow.
 

• If Statement 

It is one of the most popular control flow statements. It also helps the program to decide whether a specific condition is met. Further, the program takes the required action according to the findings.
 

• Switch Statement

The switch statement does not operate on a range of values. But, every case in a switch statement must depend on a single value. The program runs the appropriate block of code according to the value of the switchable variable.
 

• If Inline

It helps you want to apply a value to a variable depending on the outcome of a condition. Thus, an inline if statement is a far more practical version of the if statement in C sharp.
 

• For Loop

The for loop will run a section of code until the test condition is no longer true.
 

• While Loop

Until a specific condition is still true, a while loop repeatedly executes the instructions inside the loop.
 

• Do While

There is a major difference between the do-while loop and the while loop. It is that the code inside the curly braces of a do-while loop runs at least once.
 

• Foreach Loop

You can also use a foreach loop in addition to loops when working with arrays and lists. Moreover, it will help in retrieving data from an array or list without changing it.

Future Scope of C#

The Common Language Infrastructure became the base for the creation of C#. Since it is a contemporary language, it offers high performance and scalability. Moreover, it provides security, testing, and other facets of creating an application.  A great C# developer can handle all these requirements. C# can help in creating modern desktop apps. It also supports complex back-end operations driving contemporary online applications. Thus the future is C# is bright and will grow with time.

Conclusion

C#, an object-oriented programming language is part of the .Net framework. This simple general-purpose language helps to develop various applications. These applications can be Windows, console, web, and mobile applications. C sharp or C# has syntax and features similar to programming languages like Java and C++. Learning a C# language is a profitable deal as it has great career prospects!
