Specifications

Write a C$++$ program that will aid a chemistry student with the periodic table of elements.

The text file named periodic.txt includes the basic information for each chemical element including the

code $(1$ or $2$ characters$),$ the name, the chemical number, and the chemical weight. Design a record

structure to store information for one element. Your program should then input information in the

entire file to an array of "element" record structures.

Your program should be driven by a simple menu. Allow the user to search the periodic table using

either the element code or the atomic number of the element. When you match the given user request,

provide all of the information on the element including the name, code, atomic number, and atomic

weight.

Include functions as detailed below. Consider the main tasks that are being performed and the data

"flowing" between actions. Be sure to include error checking to return an error message to the user if

either the atomic number or element code is not found in the data set. Finally, a variety of string

operations are required for this program.

LoadArray Primary responsibility: Loads periodic table array with records.

HOW: Pass the address of your structures array to the function. Use a loop to read in

the data records from the data file for each atom.

DisplayMenu Primary responsibility: Displays the program menu.

HOW: Display a menu that allows the user to search the periodic table using either the

element code or the atomic number. Return the menu selection to the calling

function.

CodeSearch Primary responsibility: Searches the structure array by element symbol$($code$).$

How: Pass the address of your structures array and the symbol for the desired

element. Set up a loop to process the array, searching for the symbol. If found, return

the array index where the element was found. If not found, return $-1.$

NumberSearch Primary responsibility: Searches the structure array by atomic number $($element

number$).$

HOW: Pass the address of your structures array and the atomic number for the desired

element. Set up a loop to process the array, searching for the atomic number. If

found, return the array index where the element was found. If not found, return $-1.$

In addition to the above functions, you should display the result of the search $($e$.$g$.$ whether the element

was found or not$)$ and the associated information.
