How do I declare jagged arrays in C#?

How do I declare jagged arrays in C#?

In C#, you can declare a jagged array by specifying the type followed by two sets of square brackets. For example: int[][] jaggedArray = new int[3][]; This creates an array with 3 rows, but each row can have a different number of columns.

Can you show me how to initialize it with values?

Sure! You can initialize a jagged array like this: int[][] jaggedArray = new int[][] { new int[] { 1, 2 }, new int[] { 3, 4, 5 }, new int[] { 6 } }; This creates a jagged array with different lengths for each row.

What if I want to access an element in the second row?

To access an element in the second row, you can use the syntax jaggedArray[1][0], which will give you the first element of the second row. In this case, it would return 3.

Can jagged arrays hold different data types?

No, jagged arrays in C# must hold elements of the same type. If you need different types, consider using an array of objects or a list.
