What is the difference between initialization and assignment in C#?

Let us understand the difference between initialization and value assignment.

Declare an array.

int []  n  // declaring

initialization

Declaring an array does not initialize the array in memory. After the array variable is initialized, you can assign a value to the array. Arrays are reference types, so you need to use the new keyword to create an instance of the array.

int n= new int[10]; // initialization

Let's assign values. You can assign values ​​to individual array elements using index numbers -

n[0] = 100;
n[1] = 200

With C# you can declare, initialize and assign values ​​to an array in one line -

int n= new int[10] {100, 200, 300, 400, 500};

When creating an array, the C# compiler will implicitly initialize each array element to a default value based on the array type. For example, for an int array, all elements are initialized to 0.
