In C# and Java [5] jagged arrays can be created with the following code: [6] int [][] c ; c = new int [ 2 ][]; // creates 2 rows c [ 0 ] = new int [ 5 ]; // 5 columns for row 0 c [ 1 ] = new int [ 3 ]; // create 3 columns for row 1
Elements can be removed from the end of a dynamic array in constant time, as no resizing is required. The number of elements used by the dynamic array contents is its logical size or size, while the size of the underlying array is called the dynamic array's capacity or physical size, which is the maximum possible size without relocating data.

For example, Lua provides tables. Although Lua stores lists that have numerical indices as arrays internally, they still appear as dictionaries. [4] In Lisp, lists are the fundamental data type and can represent both program code and data. In most dialects, the list of the first three prime numbers could be written as (list 2 3 5).
The following list contains syntax examples of how to determine the dimensions (index of the first element, the last element or the size in elements). Some languages index from zero. Some index from one. Some carry no such restriction, or even allow indexing by any enumerated type, not only integers.
The cross product operation is an example of a vector rank function because it operates on vectors, not scalars. Matrix multiplication is an example of a 2-rank function, because it operates on 2-dimensional objects (matrices). Collapse operators reduce the dimensionality of an input data array by one or more dimensions. For example, summing ...
“You can still get things done and be effective when multitasking, but it usually comes at the cost of tasks taking more time or having more errors.” Studies back that up — and show exactly ...
For example, in the Pascal programming language, the declaration type MyTable = array [1..4,1..2] of integer, defines a new array data type called MyTable. The declaration var A: MyTable then defines a variable A of that type, which is an aggregate of eight elements, each being an integer variable identified by two indices.
Like forward walking, retro walking is also a great way to get in some low-impact cardio. “Any type of cardio workout has the potential to improve your cardiovascular endurance ,” says Yu.
