Create a program that allows the user to enter additional information into the structure array you created in Problem 11.18. Use your program to add the following data to the array:

11.18 Store the information presented in Problem 11.17 in a structure array. Use your structure array to determine the element with the maximum density.

11.7 Consider the following information about metals:

(a) Create the following arrays:

• Store the name of each metal into an individual character array, and store all these character arrays into a cell array.

• Store the symbol for all these metals into a single padded character array.

• Store the atomic number into an int8 integer array.

• Store the atomic weight into a double-precision numeric array.

• Store the density into a single-precision numeric array.

• Store the structure into a single padded character array.

(b) Group the arrays you created in part (a) into a single cell array.

(c) Extract the following information from your cell array:

• Find the name, atomic weight, and structure of the fourth element in the list.

• Find the names of all the elements stored in the array.

• Find the average atomic weight of the elements in the table. (Remember, you need to extract the information to use in your calculation from the cell array.)
