Difference Between if-else and switch: A Side-by-Side Comparison of If-Else and Switch Case

The If-Else and Switch statements allow you to make decisions based on the outcome of an expression. If-else operates through linear search whereas the Switch statement uses binary search. “If-else” and “switch” are conditional statements, but they work in different ways.

In this article, we will understand the key differences between If-Else and Switch statements in C#.



Local vs Global Variables: Understanding the Difference between Local and Global Variables in C#

The main difference between local and global variables is that local variables can be accessed only within the function or block in which they are defined, whereas global variables can be accessed globally throughout the entire program.

In this article, we will try to understand the fundamental concepts of local and global variables, their use cases, Pros and Cons, and how to use them effectively in our code.

C# stack vs heap: Understanding the difference between Stack and Heap memory in C#

Stack vs Heap: In C#, Stack and Heap are two important memory allocation structures that every programmer should understand.

The Stack is a Last-In-First-Out (LIFO) data structure that temporarily stores data with a short lifespan, such as function call parameters and local variables.

It is used for short-term memory allocation, ideal for data that is needed only within the scope of a method or function. The Data in the Stack memory is automatically deallocated when the method’s scope (function or block) is exited.

Stack memory is typically faster to allocate and deallocate than heap memory but has a fixed size, which can lead to stack overflow errors if exhausted.

On the other hand, A Heap is a dynamic memory allocation structure used for objects with a longer lifespan, but be aware of managing their memory properly (or relying on the garbage collector in C#). 

Objects created using the new keyword are typically allocated on the Heap.

The main difference between the two is that Stack memory is allocated and deallocated in a predictable and deterministic manner, while Heap memory is allocated dynamically and can lead to fragmentation over time.

Readonly vs const in C#: Understand the Key difference between readonly and const keyword in C#

Difference between const and readonly:

The primary difference between readonly and const keywords is that const represents a compile-time constant, whereas readonly is a runtime constant.

  • const values must be defined at the time of declaration, while readonly fields can be initialized at the declaration time or in the constructor.
  • Furthermore, const is implicitly static and is embedded in the Intermediate Language (IL) code of every assembly that uses them, while readonly variables are stored in heap memory.

In this article, We will look at the differences between the readonly and const keywords in and when to use each.

C# Field vs Property (with Examples)

C# Field Vs Property: The main difference between a Field and a Property in C# is that a field is simply a variable of any type declared within a class or struct, whereas a property is a class member that offers a convenient way to access, modify, or calculate the value of a private field.

Fields are standard class variables, and properties are an abstraction for accessing their values.
In this tutorial, you will learn about the difference between field and property in C# and how to use them effectively.

URL vs URI: The Ultimate Guide to Understanding the difference between URL and URI

URL (Uniform Resource Locator) and URI (Uniform Resource Identifier) are both terms used to identify and locate resources on the internet. Despite being used interchangeably, there is a distinct difference between the two.
While a URL specifically provides the exact location of a resource on the internet, a URI can identify a resource in a broader sense and can include both its location (URL) and unique identifier (URN).
In this post, we will learn about the key differences between URL and URI and provides guidelines for choosing between them.

Is vs As operator in C#: Understanding the differences between is and as operator in C#

is vs as operator in c#:

In C#, the IS and AS operators are essential keywords used to determine the type of an object during runtime.
The IS operator checks the type of an object and returns a boolean value, which is true if the object is of the same type and false if not. On the other hand, the AS operator not only checks the type of an object but also performs a type conversion if the object is compatible with the given type.

Difference Between UNION and UNION ALL in SQL

When comparing UNION with UNION ALL, there is a significant difference:

  • UNION returns only unique records, while UNION ALL returns all records, including duplicates.
  • UNION performs additional processing to identify and eliminate duplicate rows, which can make it slower compared to UNION ALL.

In this article, we will look at the differences between UNION and UNION ALL in SQL with multiple examples.

Having VS Where Clause in SQL | Explore the main Differences between Where and Having Clause in SQL

What is the difference between the HAVING and WHERE clause? This is one of the most frequently asked questions in interviews, particularly among freshers.

The main difference between the WHERE and HAVING clauses in SQL is that the WHERE clause filters individual rows before grouping, while the HAVING clause filters groups of rows after grouping based on aggregate conditions such as MIN, MAX, SUM, AVG, COUNT, and so on.

In simple terms, WHERE is for filtering rows, and HAVING is for filtering groups.
Additionally, it is important to note that aggregate functions can be used with the HAVING clause but not with the WHERE clause.

Let’s first understand what these clauses are used for in SQL.



C# dispose vs finalize – Understanding the difference between dispose and finalize in C#

Dispose() and finalize() are two important methods used for releasing resources in C#. These methods are used for cleaning up resources like database connections and files if they are no longer required. but there are some significant differences between the dispose and finalize methods in C#.

In C#, Dispose() and Finalize() are methods that are used to release unmanaged resources held by an object. The Dispose() method is defined in the IDisposable interface, whereas the Finalize() method is defined in the Object class. The Dispose() method can be called explicitly by the user, whereas Finalize() method is automatically called by the GC (garbage collector) before an object is destroyed.
