Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A two-dimensional array Array ____ 2d consists of data:[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]. What is the output of print(Array ____ 2d[1])?
A
[1, 2, 3, 4]
B
[5, 6, 7, 8]
C
[9, 10, 11, 12]
D
None of the above
Explanation: 

Detailed explanation-1: -int x[3][4]; Here, x is a two-dimensional array. It can hold a maximum of 12 elements. We can think of this array as a table with 3 rows and each row has 4 columns as shown below.

Detailed explanation-2: -A two-dimensional array is a data structure that contains a collection of cells laid out in a two-dimensional grid, similar to a table with rows and columns although the values are still stored linearly in memory.

Detailed explanation-3: -Explanation: The element at the ith row and jth column of an array are equal to *(*(arr + i) + j). In this code, first, we declare and initialize the array, following which we loop over the 2D array using 2 loops, and print each element of the array using *(*(arr + i) + j). Thus the entire 2D array is printed.

Detailed explanation-4: -The size of a two dimensional array is equal to the multiplication of number of rows and the number of columns present in the array.
