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

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

Jagged arrays are arrays of arrays, allowing for different lengths, while rectangular 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 rectangular array looks like this: int[,] rectangular = new int[2,3];.

What are the advantages of using one over the other?

Jagged arrays are more flexible in size, while rectangular arrays are more efficient for fixed-size data.

When should I use a jagged array instead of a rectangular array?

Use jagged arrays when you need to store data of varying lengths, like a list of students with different grades.
