What does a row look like?

Answer 1

Arrays do not have rows as such. An array is a series of N variables, where each of the N variables can be accessed through a numeric index.

In traditional programming languages, all N elements must share the same data type, and the size of the array (its number N) is constant. This is not always true; more modern languages supply variable-size arrays or arrays that support different types of data helpd by the different elements. However, all arrays share the same key characteristic: each individual element Z can be accessed with an index, typically in the 0...(N-1) range, and each element Z can be accessed in the same time, regardless of the numeric value of that index.

Modern programming languages also support associative arrays, which support non-numeric indices while trying to accomplish the same constant-time performance characteristic.

Traditionally, simple arrays are often visualized as a series of data elements, arranged in a row. For example, an array of four string" elements can be visualized as omelette = [ "eggs", "flour", "milk", "salt" ]; Because each element within one array can itself be an array, an array or arrays can be visualized as a grid of array elements, each addressed through a combination of row and column indices. In this interpretation, a row of an array is a row of N elements (N columns) in a grid of M rows.

In traditional programming languages such as C, all rows in such a two-dimensional array share the same length N, but modern languages support jagged arrays, where rows in a two-dimentional grid of M rows are not required to share the same length N.

The concept of rows and columns applies to two-dimensional arrays only. It may be used with three-dimensional arrays, but there, the terminology is ambiguous. A row- and column-based terminology is not generally useful in a Z-dimensional array where Z > 2.

Answer 2

Row (also called as record, is the horizontal line in a table) is the set of fields within a table that are relevant to a specific entity.

_Column_ ________

|___V______^ ___| -> Row

|___V______^ ___| -> Row

|___V______^ ___| -> Row

|___V____Column_| -> Row

consider a spreadsheet as a table with rows and columns. usually, a row or record represents an object of some kind.

Example:

person accountname

martien martiendejong

john johnsmith

greg admingreg

in this example the rows represent users.

Answer 3

In chemistry rows is the name that was given to what are now more often called periods in the Periodic Table.

Answer 4

It goes horizontally (sideways)
