C++ programming chemical compounds. Thank you!

Hint:

/***************************************** 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 main function: chem_main.cc
 
#include #include #include #include using namespace std; // The chemical class class Chemical{ // This is one of the parts that you write }; // This function shows the user their choices and returns // the menu item they have selected int menu(); // The main for the project int main(){ ifstream fin; ofstream fout; Chemical element, molecule; string chemsym; int multiplier; int chosen; fin.open("elements.txt"); if(fin.fail()){ cout>chemsym; element.get_element(chemsym, fin); break; case 3: cout>multiplier; element = element*multiplier; break; case 4: molecule = molecule + element; break; case 5: fout>element; break; case 0: cout>choice; return choice; }

  C++ programming Chemical Compounds Spring 2017 Homework 8: A Chemical ADT The goal here is to create a C++ type that will let us "build" chemical compounds As most of you should know, a chemical element consists of protons, neutrons and electrons, and that the "chemical number is the number of protons and the "chemical weight" is the number of protons and neutrons. While the first number is always an integer, the second is generally given as a floating point, since a certain percentage of the atoms for that element are isotopes, having extra neutrons. 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 Iwant this program to do I 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 9f 1Q (1 2 8) and an atomic weight of 18.0132 (1.0079 2 15.9994). SO4 s 48 (16+4*8) and 96.0626 (32.065 4*15.9994 am going to work on the elements.txt file so that it more accurately reflects the atomic weights that actually appear in the periodic table. 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 getasusauent function that takes a string and the file stream for elements.txt 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 weigbtamH20 Nacio NaHCO3 C2H50H SiO2 PbS C12H22011 Finally you are to break your program into three files chem main.cc gbemigglh and chemical, cc  C++ programming Chemical Compounds Spring 2017 Homework 8: A Chemical ADT The goal here is to create a C++ type that will let us "build" chemical compounds As most of you should know, a chemical element consists of protons, neutrons and electrons, and that the "chemical number is the number of protons and the "chemical weight" is the number of protons and neutrons.
