A cell array has the ability to contain different types of data. In the following exercise, you will practice how to a create cell array and modify its elements.

(c) Create a column cell array. The first element of the array is a character row vector with all lower-case letters (a-z). The second element of the array is a column vector with all even numbers from 2 to 52. Store the new cell array in p2c.

(d) Put the cell array in the part (c) into p2d and modify p2d by replacing x with X in the first element of the array and dividing the second element (all content) of the array by 2.
