Program in C++: Given the main, Create a type that will let us build chemical compounds. Thank you!

*****Hint for the program:

/***************************************** The purpose of this is to provide you with a single function which will convert an integer to a string, which will be useful in homework 8 The main that appears under the function is just to demo that it works. *********************************************/ 

#include #include 

using namespace std; string itostr(int num){ string one,result; while(num > 0){ //converts the last digit of num to a char and then to a string one += static_cast(num%10)+'0'; //puts most recently converted digit at the beginning of // the result string result.insert(0,one); one = ""; // empty the one-character string num /= 10; // chop off the last digit of the number } return result; } int main(){ string sample; int anumber; cout>anumber; sample = itostr(anumber); cout

/******************************** The purpose of this project is to develop a class describing chemicals. A chemical can be either a single atom of a single element or a molecule. Addition and multiplication operations defined for the class allow us to combine elements into molecules and molecules into larger molecules. **************************************************/

  Program in C++: Create a type that will let us "build" chemical compounds. I have provided a list of the known elements in a data file called "elements.txt." The class that you write is able to store the chemical symbol (a string), the atomic number (an integer) and the atomic weight (a double) In order to clarify what I want this program to do l have already written the main for you, and you are to begin the project by copying the main and the elements.txt both located below. Now chemical elements can be added together and the resulting compound also has a chemical number and a weight, which is the sum of the numbers and weights of all the elements in the compound. H20 has a number of (1 8) and an atomic weight of 18.0132 (1.0079 2+ 15.9994). SO4 is 48 (16+4 8) and 96.0626 (32.065 4*15.9994). We are going to allow an application to build these compounds with overloaded and operators. And we are going to have the ability to output our compounds with an overloaded operator, and input them with an overloaded operator The class that you write will have: A default constructor A constructor that takes 1 argument, the name of an element A constructor that takes 3 arguments Three accessor functions A set function A get element function that takes a string and the file stream for elements.txt lt will search the file to find the element and load the correct atomic number and weight into the element of which it is a member An overloaded operator that adds two chemicals, concatenating their strings and combining their numbers An overloaded operator that multiplies a chemical and an integer, the string will have the number concatenated onto the string An overloaded operator that outputs the information about a chemical An overloaded operator that lets a chemical be loaded from keyboard or file Your program will be creating a Mychemicals.txt file (my main sets that up) List of compounds to build for that file: The MyChemicals.txt file will contain these along with their total atomic number and atomic weight H20 Nacio NaHCO3 C2H50H SiO2 PbS C12H22011 Finally you are to break your program into three files chem main.cc, chemical. h and chemical.cc
