Business HW problem C++

[audiokarate]

Hey everyone. I have this homework problem for my IS class and I am having trouble finding the variables and the next step after that. Can someone please help me out? This is the problem.

Write a program to compute telephone bills for the local telephone company. Each customer has a base charge of $12.95 per month and gets charged extra for each local call and each long-distance call. The program should prompt the user for the number of local calls made during the month. The charge for each local call is $0.10. Use the += operator to add the cost of the local calls to the total bill. Then the program should prompt the user for the total charge for long-distance calls made during the month. Use the += operator to add the long-distance charges to the total bill. Finally, the program should calculate the tax on the total bill. The Tax rate is 8.72%. Use the *= operator to add the tax to the total bill by multiplying the total bill by 1.0872.

and there it is. Any help would be greatly appreciated.

Which parts exactly are you having trouble with?

[audiokarate]

finding the variables..I already know the constants

This is what I have so far and I'm not sure if it's correct either.

#include <iostream>
#include <iomanip>
using namespace std;
 
void main ()
{
 
      Const double BASE_CHARGE_PER_MONTH = 12.95;
      Const double RATE_LOCAL_CALLS = 0.10;
      Const double TAX_RATE = 8.72;
 

and thats it?

You will need one variable which will hold the total cost for the monthly bill.

You will need a variable for the user input. (i.e. 20 calls).
other than that you have the variables that you need.

Alright so this is what I have so far. Now all I have to do is to output a customer report for example:

Base charge: $12.95
Local call charge: (value will be based on user’s input)
Long distance charge: (value will be based on user’s input)
Total Bill: (value will be based on user’s input)

This has got to show at the bottom after the bill is calculated and I am having trouble with it. I just need to get pointed in the right direction. How do I find the local call charge and input it where the parenthesis are?

base += local_calls * LOCAL_RATE;
base += long_distance * LONG_D_RATE;
base *= 1.0872;

cout << "The total bill for this month is : $" << base;
cout << endl;

return 0;

You're already calculating that value here:

base += local_calls * LOCAL_RATE;

Either recalculate the value in-line with a cout like this:

cout<< "Total Charges for Local calls: " << local_calls * LOCAL_RATE << endl;

or store the result of the first calculation in a variable, e.g.

double localCharges = local_calls * LOCAL_RATE;
base += localCharges;
.
.
.
cout << "Total Charges for Local Calls: " << localCharges << endl;
 

Hope this helps,
Ian
