Understand Basic Data Types in C# with Examples

In C# programming, data types play an important role in determining the type of data a variable can hold. Understanding basic data types is fundamental for any C# developer. In this article, we’ll delve into the essential data types in C# along with examples to illustrate their usage.

What are Data Types in C#?

Data types in C# define the type and size of data that a variable can store. C# supports various data types, including primitive types and user-defined types.

Basic Data Types in C#

1. Integer Types:

• int: Represents signed 32-bit integers. Example: int age = 30;
• uint: Represents unsigned 32-bit integers. Example: uint count = 100;
• short: Represents signed 16-bit integers. Example: short temperature = -10;
• ushort: Represents unsigned 16-bit integers. Example: ushort quantity = 500;
• long: Represents signed 64-bit integers. Example: long population = 1000000L;
• ulong: Represents unsigned 64-bit integers. Example: ulong distance = 150000UL;

2. Floating-Point Types:

• float: Represents single-precision floating-point numbers. Example: float height = 5.7f;
• double: Represents double-precision floating-point numbers. Example: double pi = 3.14159;
• decimal: Represents decimal numbers with higher precision. Example: decimal price = 99.99m;

3. Character Type:

• char: Represents a single Unicode character. Example: char grade = 'A';

4. Boolean Type:

• bool: Represents a boolean value (true or false). Example: bool isStudent = true;

5. String Type:

• string: Represents a sequence of characters. Example: string name = "John Doe";

Examples and Usage:

using System;

class Program
{
    static void Main()
    {
        // Integer Types
        int age = 30;
        uint count = 100;
        short temperature = -10;
        ushort quantity = 500;
        long population = 1000000L;
        ulong distance = 150000UL;

        // Floating-Point Types
        float height = 5.7f;
        double pi = 3.14159;
        decimal price = 99.99m;

        // Character Type
        char grade = 'A';

        // Boolean Type
        bool isStudent = true;

        // String Type
        string name = "John Doe";

        Console.WriteLine("Age: " + age);
        Console.WriteLine("Count: " + count);
        Console.WriteLine("Temperature: " + temperature);
        Console.WriteLine("Quantity: " + quantity);
        Console.WriteLine("Population: " + population);
        Console.WriteLine("Distance: " + distance);
        Console.WriteLine("Height: " + height);
        Console.WriteLine("Pi: " + pi);
        Console.WriteLine("Price: " + price);
        Console.WriteLine("Grade: " + grade);
        Console.WriteLine("Is Student: " + isStudent);
        Console.WriteLine("Name: " + name);
    }
}

In this example, we’ve declared variables of various basic data types and assigned values to them. The Main method then prints out the values of these variables to the console.

Conclusion:

Understanding basic data types is foundational in C# programming, as it allows developers to work with different kinds of data efficiently. By mastering these data types, developers can write robust and reliable C# code.

I hope this article helps you grasp the basics of data types in C# programming. Happy coding!
