Problems with logic

how would i put the savings if the person picks package(1) to how much they would have saved if they had picked package(2)..

heres my code..

#include <iostream>
#include <string>
using std::cout;
using std::cin;
using std::endl;
using std::string;

int main () {

int pause;
int package;
int hours;
int savings;
double amountdue;
const double package_1= 9.95, package_2= 14.95, package_3=19.95;
string Fname;
string Lname;

cout << "Please enter both your first and last name: \n" << endl;
cin >> Fname;
cin >> Lname;

cout << "Please type 1, 2, or 3 for the internet package you purchased?: \n" << endl;
cout << " " << "Package(1)\n";
cout << " " << "Package(2)\n";
cout << " " << "Package(3)\n";
cin >> package;

cout << "Please enter how many hours did you use for this month?\n" << endl;
cin >> hours;



if (package==1)

{
if (hours >= 1 && hours <= 10)
{

cout << "Customer Name: " << Fname << " " << Lname;
cout << "\nPackage Purchased: " << package;
cout << "\nHours Used: " << hours;
cout << " \nThe total amount due is $" << package_1;

}
if (hours >=10 && hours <=744)
{
amountdue = package_1 + ((hours-10) * 2.0);
cout << "Customer Name: " << Fname << " " << Lname;
cout << "\nPackage Purchased: " << package;
cout << "\nHours Used: " << hours;
cout << " \nThe total amount due is $" << amountdue;
}


}


else if (package==2)

{

if (hours > 0 && hours <= 20)
{

cout << "Customer Name: " << Fname << " " << Lname;
cout << "\nPackage Purchased: " << package;
cout << "\nHours Used: " << hours;
cout << " \nThe total amount due is $" << package_2;
}
if (hours >= 20 && hours <= 744)
{
amountdue=package_2+((hours-20)*1.0);
cout << "Customer Name: " << Fname << " " << Lname;
cout << "\nPackage Purchased: " << package;
cout << "\nHours Used: " << hours;
cout << " \nThe total amount due is $" << amountdue;
}

}


else if (package==3)
{
if (hours > 20 && hours < 744)
{

cout << "Customer Name: " << Fname << " " << Lname;
cout << "\nPackage Purchased: " << package;
cout << "\nYour hours are unlimited ";
cout << " \nThe total amount due is $" << package_3;
}


}

if (package <=0 || package >=4)
{
cout << " That is an invalid package choice!";
}

if (hours <= 0 || hours >=744)
{
cout << "That is an invalid hours choice!";
}

cin >> pause;
return 0;
}

Hi,crawfoosh
In ur programme,there 5
cout << "Customer Name: " << Fname << " " << Lname;
cout << "\nPackage Purchased: " << package;
cout << "\nHours Used: " << hours;
cout << " \nThe total amount due is $" << package_1;


If inist on finishing ur logic use ur programm that will be a hard work.
some advice to You:

1,define a function only to count how much with given package and hours
2,call the function above,you can count out how much each of the package
will cost ,then compare them!

there is a example for step 1:
1
2
3
4

double cost(int package,int hours)
{
	double result=0;

	if(package == 1)
	{
		if (hours >= 1 && hours <= 10)
		{
			result = package_1;
		}
		if (hours >=10 && hours <=744)
		{
			result = package_1 + ((hours-10) * 2.0);
		}
		
		return result;
	}
	else if(package == 2)
	{
		if (hours >= 1 && hours <= 20)
		{
			result = package_2;
		}
		if (hours >=20 && hours <=744)
		{
			result = package_2 + ((hours-10) * 2.0);
		}
		
		return result;
	}
	else if(package == 3)
                   //ur package have some problem
                   //in ur programm,what will happen if hours < 20
	{
		if (hours >= 1 && hours <= 10)
		{
			result = package_3;
		}
		if (hours >=30 && hours <=744)
		{
			result = package_3 + ((hours-10) * 2.0);
		}
		
		return result;
	}
}


based on ur programm,I have finished a workable program:
