Which of the following statements represents the number of columns in a regular two-dimensional array named values?
puteri [66]

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

<em>arrayname.length</em>

For example, to get the number of rows in array b above, we simply write;

<em>b.length </em>which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

<em>arrayname[0].length</em>

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

<em>b[0].length </em>which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length

Utilizando o padrão de medidas e unidades do National Institute of Standards and Technology, em que 1 KB é igual a 1.000 Bytes,
Tanya [424]

Segundo o padrão da  National Institute of Standards and Technology a  alternativa correta é a letra E) 400 músicas.  Segundo o padrão disposto acima, dois Giga Bytes equivalem à dois mil Mega Bytes, assim, se cada música tem exatos 5MB, podemos chegar ao total de músicas que podem ser gravadas em um PenDrive de 2GB livres do seguinte modo :

x=\frac{2000 MB}{5MB};x=400

 A evolução da microeletrônica possibilitou uma capacidade de armazenamento cada vez maior a cada ano. O desenvolvimento de novas tecnologias na área permite também que os produtores possam produzir músicas, fotos e vídeos com cada vez mais qualidade (consequentemente mais pesada).
