What are the differences between jagged and multidimensional arrays in C#?

What are the differences between jagged and multidimensional arrays in C#?

Jagged arrays are arrays of arrays, allowing for different lengths, while multidimensional arrays have a fixed size.

Can you give me an example of each type?

Sure! A jagged array can be defined like this: int[][] jagged = new int[2][]; jagged[0] = new int[3]; jagged[1] = new int[2]; A multidimensional array looks like this: int[,] multi = new int[2,3];.

Which one is more efficient in terms of memory?

Jagged arrays can be more memory efficient if the sub-arrays are of varying lengths, while multidimensional arrays use a contiguous block of memory.

When should I use one over the other?

Use jagged arrays when you need flexibility in size, and multidimensional arrays when you need a fixed-size grid structure.
