Jagged array
In computer science a jagged array, also known as a ragged array, is a type of multidimensional array data structure whose elements consist of one-dimensional arrays, hence it is an "array of arrays". The array is called "jagged" because the elemental arrays can be of different dimensions and sizes.[1] In contrast, C-styled arrays are always rectangular.[2]
Multidimensional arrays in languages such as Java, Python (multidimensional lists), Ruby, Visual Basic.NET, Perl, PHP, JavaScript, Objective-C, Swift, and Atlas Autocode are implemented as Iliffe vectors.
Example
In C#, jagged arrays can be created with the following code:[3]
int[][]c;
c=new int[2][]; // creates 2 rows
c[]=new int[5]; // 5 columns for row 0
c[1]=new int[3]; // create 3 columns for row 1
