please help me fix and finish off my assignment

Question: An Internet service provider has three different subscription packages for its customers.
Package A: For $9.95 per month 5 hours of access are provided. Additional usage costs $0.08 per minute.
Package B: For $14.95 per month 10 hours of access are provided. Additional usage costs $0.06 per minute.
Package C: For $19.95 per month unlimited access are provided.

Write a program that calculates and lists a customer’s monthly bill. A user should input customer name, which package the customer has purchased, and how many hours were used. It should then create a bill that includes the input information and the total amount due.

Input Validation: Be sure the user only selects package A, B, or C.

#include <iostream>
using namespace std;

int main ()
{
  //Declaration.
  
int choice;
int hours;
int choixOperation;
int name;
double total;

double A = 9.95;
double B = 14.95;
double C = 19.95;
double D = 0.08;
double E = 0.06;

 //Display.

cout << " \t\tThe Internet Service Provider Subscription\n";
cout << "1. A.$9.95 per month. 5 hours access. Additional Minutes are $0.08\n";
cout << "2. B.$14.95 per month. 10 hours access. Additional minutes are $0.06\n";
cout << "3. C.$19.95 per month. Unlimited access.\n";
cout << "Enter your choice: ";
cin >> choice;

 //Calculation.
 
if (choice >=1 && choice <=3)
{
  //Input information 
  
cout << "Can I have your full name please: ";
cin >> name;
 //Neeed!!
 
cout << "How many hours would you access: ";
cin >> hours;

 //Decision.

switch (choixOperation)
{
case 1:
{
total = A + (hours - 5)*(.08);
break;
}
case 2: 
{
total = B + (hours - 10)*(.06);
break;
}

case 3: 
{
total = C;
break;
}

I have not been able to continue the rest where it should create the bill that includes the input information and the total amount due. Please help, with any error fixes and help on the last part to display the bill.

so can i remove lines 17, 18:

    double D = 0.08;
    double E = 0.06;

for line 39 i would have to connect it with plans 1 and 2?
with total plan1= (hours + cost - hours) * 0.8 or 0.6 like the line i have in 52-63?

   cout << "How many hours would you access: ";

but how do i declare cost without it being a function?
can i use this code??

  double aCost = cost(minutes, 'A');
  double bCost = cost(minutes, 'B');
  double cCost = cost(minutes, 'C');
  double yourCost = cost(minutes, plan);

If you're not going to use them in your program, remove them.

Yes.

but how do i declare cost without it being a function?
can i use this code??

If you don't want to declare cost without using a function, just perform the basic computation for the cost like what you did for your original code. You may use a function as well to do the computations.
