I completed my post-graduation in 2013 in the engineering field. Engineering is the application of science and math to solve problems. Engineers figure out how things work and find practical uses for scientific discoveries. Scientists and inventors often get the credit for innovations that advance the human condition, but it is engineers who are instrumental in making those innovations available to the world. I love pet animals such as dogs, cats, etc.

You can sort an array using various methods provided by the language.
Here are a few common ways to do it:

Using Array.Sort Method
The Array.Sort method is a simple and efficient way to sort arrays of primitive types or objects that implement the IComparable interface:

int[] numbers = { 3, 1, 4, 1, 5, 9, 2, 6, 5 };
Array.Sort(numbers);

Using Array.Sort with Comparison Delegate
You can also use the Array.Sort method with a comparison delegate to define custom sorting logic:

string[] names = { "John", "Alice", "Bob", "Eve" };
Array.Sort(names, (x, y) => string.Compare(x, y));

Using LINQ OrderBy Method
If you're working with arrays of objects, you can use LINQ's OrderBy method to sort them based on a specified key:

string[] names = { "John", "Alice", "Bob", "Eve" };
names = names.OrderBy(name => name).ToArray();

Using LINQ OrderByDescending Method
Similarly, you can use LINQ's OrderByDescending method to sort in descending order:

string[] names = { "John", "Alice", "Bob", "Eve" };
names = names.OrderByDescending(name => name).ToArray();

Using Custom Comparison Logic
If you need to sort based on custom logic, you can implement the IComparer<T> interface and use the Array.Sort method overload that takes an IComparer<T> parameter:

class CustomComparer : IComparer<int>
{
   public int Compare(int x, int y)
   {
       // Custom comparison logic
       return x.CompareTo(y);
   }
}
int[] numbers = { 3, 1, 4, 1, 5, 9, 2, 6, 5 };
Array.Sort(numbers, new CustomComparer());

Result
Regardless of the method you choose, the array will be sorted in ascending order by default, or in the specified order based on the comparison logic provided. Adjust the sorting logic according to your requirements.
