I need this is c++
Write a program that calculates and prints the bill for a cellular telephone
company. The company offers two types of service: regular and premium.
Its rates vary, depending on the type of service. The rates are computed as
follows:
Regular service: $10.00 plus first 50 minutes are free. Charges for
over 50 minutes are $0.20 per minute.
Premium service: $25.00 plus:
a. For calls made from 6:00 a.m. to 6:00 p.m., the first 75 minutes are free;
charges for more than 75 minutes are $0.10 per minute.
b. For calls made from 6:00 p.m. to 6:00 a.m., the first 100 minutes are
free; charges for more than 100 minutes are $0.05 per minute.
Your program should prompt the user to enter an account number, a
service code (type char), and the number of minutes the service was
used. A service code of r or R means regular service; a service code of
p or P means premium service. Treat any other character as an error.
Your program should output the account number, type of service,
number of minutes the telephone service was used, and the amount
due from the user.
For the premium service, the customer may be using the service during
the day and the night. Therefore, to calculate the bill, you must ask the
user to input the number of minutes the service was used during the day
and the number of minutes the service was used during the night.
thank you!

#include<iostream>
using namespace std;
int main()
{
int acc,ddur,ndur,dur,ncst,dcst;
float tot,cst;
char srv;
cout<<"Enter the account number:";
cin>>acc;
cout<<"Type of service:";
cin>>srv;
switch(srv)
{
case 'r':cout<<"Enter the duration in minutes:";
cin>>dur;
dur-=50;
cst=dur*0.2;
tot=cst+10;
cout<<acc<<" "<<srv<<" "<<tot;
break;
case 'R':cout<<"Enter the duration in minutes:";
cin>>dur;
dur-=50;
cst=dur*0.2;
tot=cst+10;
cout<<acc<<" "<<srv<<" "<<tot;
break;
case 'p':cout<<"Enter the day duration in minutes:";
cin>>ddur;
cout<<"Enter the night duration in minutes:";
cin>>ndur;
ddur-=70;
dcst=ddur*0.1;
ndur-=100;
ncst=ndur*0.05;
tot=ncst+dcst+25;
cout<<acc<<" "<<srv<<" "<<tot;
break;
case 'P':cout<<"Enter the day duration in minutes:";
cin>>ddur;
cout<<"Enter the night duration in minutes:";
cin>>ndur;
ddur-=70;

ndur-=100;
ncst=ndur*0.05;
tot=ncst+dcst+25;
cout<<acc<<" "<<srv<<" "<<tot;
