What are jagged arrays in C# and can you give me some examples?

Jagged arrays in C# are arrays of arrays, where each 'inner' array can have different lengths. For example, you can declare a jagged array like this: int[][] jaggedArray = new int[3][]; and then initialize it with different lengths.

Can you show me how to initialize a jagged array with values?

Sure! You can initialize a jagged array like this: int[][] jaggedArray = new int[2][]; jaggedArray[0] = new int[] { 1, 2, 3 }; jaggedArray[1] = new int[] { 4, 5 }; This creates a jagged array with two inner arrays of different lengths.

How do I access elements in a jagged array?

To access elements, you can use the syntax jaggedArray[row][column]. For example, jaggedArray[0][1] would give you the value 2 from the first inner array.

What are some use cases for jagged arrays?

Jagged arrays are useful when you need to store data in a non-uniform structure, like representing a matrix where each row can have a different number of columns, such as in a game score table.
