c++ looping statement on package pricing - c++

Question

I'm trying to make a loop statement to determine the prices according to their respective packages but I can't seem to get a grasp of the do and while statements.
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
const double W_adult=47.90, W_child=41.50, W_senior=35.40, A_adult=25.90, A_child=20.50, A_senior=15.40, P_adult=15.90, P_child=12.50, P_senior=10.40;
double totaladult,totalchild,totalsenior, total;
int noadult,nochild,nosenior;
char option;
//char choice = 'y'; looping choice
cout<<"WELCOME TO WAS LOST WORLD THEME PARK\n\n"<<endl;
cout<<setw(80)<<setfill('*')<<"*";
cout<<"\nPackage name \t | ADULT\t | CHILD\t | SENIOR CITIZEN"<<endl;
cout<<"|A| Water Park\t | 47.90\t | 41.50\t | 35.40"<<endl;
cout<<"|B| Am. Park\t | 25.90 \t | 20.50 \t | 15.40"<<endl;
cout<<"|C| Pet. Zoo\t | 15.90\t | 12.50\t | 10.40"<<endl<<endl;
cout<<setw(80)<<setfill('*')<<"*";
cout<<"\nChoose your package A/B/C: "<<endl;
cin>>option;
cout<<"Enter the no of adult: "<<endl;
cin>>noadult;
cout<<"Enter the no of child: "<<endl;
cin>>nochild;
cout<<"Enter the no of senior citizen: "<<endl;
cin>>nosenior;
switch(option)
{
case 'A':
case 'a':
totaladult=W_adult*noadult;
totalchild=W_child*nochild;
totalsenior=W_senior*nosenior;
break;
case 'B':
case 'b':
totaladult=A_adult*noadult;
totalchild=A_child*nochild;
totalsenior=A_senior*nosenior;
break;
case 'C':
case 'c':
totaladult=P_adult*noadult;
totalchild=P_child*nochild;
totalsenior=P_senior*nosenior;
break;
}
cout<<"Total no of adult is: "<<noadult<<endl;
cout<<"Total no of child is: "<<nochild<<endl;
cout<<"Total no of senior citizen is: "<<nosenior<<endl;
cout<<"Total price of adult is: "<<totaladult<<endl;
cout<<"Total price of child is: "<<totalchild<<endl;
cout<<"Total price of senior citizen is: "<<totalsenior<<endl;
cout<<"The total price is: "<<totaladult+totalchild+totalsenior<<endl;
return 0;
}
Is there something else I'm missing here? Currently it only calculates the price of one category. I would like know where should I include the loop statements.

Answer 1

you should add an option to quit, and while loop as long as the user keep selecting packages:
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
const double W_adult=47.90, W_child=41.50, W_senior=35.40, A_adult=25.90, A_child=20.50, A_senior=15.40, P_adult=15.90, P_child=12.50, P_senior=10.40;
double totaladult = 0,totalchild = 0,totalsenior = 0, total = 0;
int noadult = 0,nochild = 0,nosenior = 0;
char option;
bool run = true;
//char choice = 'y'; looping choice
cout<<"WELCOME TO WAS LOST WORLD THEME PARK\n\n"<<endl;
cout<<setw(80)<<setfill('*')<<"*";
cout<<"\nPackage name \t | ADULT\t | CHILD\t | SENIOR CITIZEN"<<endl;
cout<<"|A| Water Park\t | 47.90\t | 41.50\t | 35.40"<<endl;
cout<<"|B| Am. Park\t | 25.90 \t | 20.50 \t | 15.40"<<endl;
cout<<"|C| Pet. Zoo\t | 15.90\t | 12.50\t | 10.40"<<endl<<endl;
cout<<setw(80)<<setfill('*')<<"*";
while(run)
{
cout<<"\nChoose your package A/B/C --- or Q to quit: "<<endl;
cin>>option;
cout<<"Enter the no of adult: "<<endl;
cin>>noadult;
cout<<"Enter the no of child: "<<endl;
cin>>nochild;
cout<<"Enter the no of senior citizen: "<<endl;
cin>>nosenior;
switch(option)
{
case 'A':
case 'a':
totaladult+=W_adult*noadult;
totalchild+=W_child*nochild;
totalsenior+=W_senior*nosenior;
break;
case 'B':
case 'b':
totaladult+=A_adult*noadult;
totalchild+=A_child*nochild;
totalsenior+=A_senior*nosenior;
break;
case 'C':
case 'c':
totaladult+=P_adult*noadult;
totalchild+=P_child*nochild;
totalsenior+=P_senior*nosenior;
break;
case 'q':
case 'Q':
run = false;
break;
default:
// do nothing
break;
break;
}
cout<<"Total no of adult is: "<<noadult<<endl;
cout<<"Total no of child is: "<<nochild<<endl;
cout<<"Total no of senior citizen is: "<<nosenior<<endl;
cout<<"Total price of adult is: "<<totaladult<<endl;
cout<<"Total price of child is: "<<totalchild<<endl;
cout<<"Total price of senior citizen is: "<<totalsenior<<endl;
cout<<"The total price is: "<<totaladult+totalchild+totalsenior<<endl;
}
return 0;
}
