What is the method for defining and assigning values to…

In C#, you can define and assign values to a two-dimensional array using the following methods:

1. You can create a 2D array using the keyword “new” and initialize the elements of the array using curly braces {}. For example:

int[,] array = new int[3, 2] { { 1, 2 }, { 3, 4 }, { 5, 6 } };

In the example above, we created a 3 by 2 two-dimensional integer array and assigned initial values to each element.

1. Create a 2D array using the keyword ‘new’ and assign values to each element using index positions. For example:

int[,] array = new int[3, 2];
array[0, 0] = 1;
array[0, 1] = 2;
array[1, 0] = 3;
array[1, 1] = 4;
array[2, 0] = 5;
array[2, 1] = 6;

In the example above, we created a 3×2 two-dimensional integer array and assigned values to each element one by one.

1. Create a two-dimensional array using initializer syntax and assign a value to each element. For example:

int[,] array = { { 1, 2 }, { 3, 4 }, { 5, 6 } };

In the example above, we created a 3 by 2 two-dimensional integer array and assigned initial values to each element.

Regardless of the method used to define and assign values to a two-dimensional array, elements of the array can be accessed and modified by their index positions. For example, to access the first element of a two-dimensional array, you can use array[0, 0], where the first index represents the row number and the second index represents the column number.
