Periodic Table
Consider that a file atomic.txt
contains a data of 103 different periodic elements. The first column is a atomic number, the second is
the name, the third is symbol and so on. Last two columns are melting point and boiling point in oC respectively.
Unknown property of an atom is assigned to a value of -1. Here is the part of the data file:
Write a C++ program that reads the data from the file into suitable vectors and then outputs a menu (given below)
to read an option from the keyboard:
******************************* MENU ***********************************
* *
* 0. Exit *
* 1. List properties of a specific atom *
* 2. List all properties of the elements belonging to a group *
* 3. List all properties of the elements belonging to a period *
* 4. List all properties of the elements for a given the description *
* 5. List all properties of the elements for a given the state at STP *
* 6. List all properties of the elements for a given boiling point range *
* 7. List all properties of the elements for a given melting point range *
* *

what is your choice? 1
- If the choice is 1 then program must read an atomic number (Z) from the keyboard and output all properties of the chosen element.
In this case, for Z = 1, the output of the program and its format should look like:
Input atomic number: 4
