Question

When mathematicians use a two-dimensional array, they often call it a ____.

a.
matrix

b.
grid

c.
net

d.
mesh

Answer 1

matrix

Step-by-step explanation:

The two dimensional array store the value similar to matrix.

Two dimensional array contain row and column similar to matrix.

For example:

int arr[3][3], it means 3 rows and 3 column

and
`[A]_(3*3)=\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]`

and if we want to retrieve the data from array arr[1][2], it means first row and second column.

so, 2 dimensional array is basically a matrix.
