    #include <iostream>
    #include <cmath>
    #include <fstream>
    #include <cstdlib>
    #include <string>
    using namespace std;
    // A: define variableone
    // B: define string name
    class one
    		one(int a); // A2: this is the declaration of a fubction that will be used to give variableone a value
    		void printvariableone();
    		int variableone; // A1: it starts here with a declaration
    class two
    		two(string x, one oneobject); // B2: the declaration of a function that will define the string and a class one object
    		void printstring();
    		string name; // B1: this declares a string called name
    		one oneref; // B1A: an object to reference class one
    one::one(int a) // A3: this will set variableone to the value of a, which will be given in main
        {variableone = a;}
    // to print the stuff
    void one::printvariableone()
        {cout << variableone << endl;}
    two::two(string x, one oneobject) // B3: this member initializing sets the string x to the string name and the object to oneref
    : name(x), oneref(oneobject)
    void two::printstring()
            cout << name << endl;
    int main()
    	one mainObj(6); // A4: apparently this passes 6 to the class one constructor via an object
    	two peopleobject("Stephon", mainObj); // this line uses an object to reference class two constructor and pass a string and an object
    	// to print both
    	return 0;

    Without objects how can you use classes??

    Please elaborate more if you want some precise answers here.
