Storing outputs

[doc17]

Im doing a program for a parking garage.

Im trying to save the cost of each car that leaves the garage then totak it at the end.

 

#include <cstdlib>
#include <iostream>
#include <math.h>


using namespace std;

int main(int argc, char *argv[])
{
    int cars = 0;
    int userChoice;
    const int flatRate = 6; 
    const double hourlyFee = 2.50;
    double customerFee = 0;
    int carHours; 
     
 ...


    cout <<  " Do you want to exit? if so enter -1 if enter any key" << endl;
    cin >> userChoice;
   
   if (userChoice != -1) 
     {
       cars += 1;// record ammount of cars input into program
       cout << cars << endl;
     }
     
}
 while (userChoice != -1);  
       
       cout << " The total number of Cars for today was: " << cars << endl; 
       cout << "Have a nice Day" << endl; 
    
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

 

how can i store the charge of each car?

[mutexe]

on line 18 say..

double totalCost(0.0);

Then when you increment the number of cars (line58?):

totalCost+=customerFee;

edit: i would also initialise your 'customerFee' to zero at the very top of your do while loop (before your first if statement for example), rather than outside.

mutexe can i ask one more question the program is not receiving the last car ( if i get the price of 4 cars it only registers up until 3 and disregards 4) is it a matter of moving car+=1 ?

[mutexe]

pretty much yes. As you can see on line 56 if the user enters -1 the last car is not added.
you may as well do the increment as soon as you're in the do while loop i think.

edit: actually, delete lines 56, 57 and 60. That should do it.

okay thank you very much

[mutexe]

Can i make one more suggestion?
Change:

int userChoice;

to

char userChoice;

then do something like this:

// increment number of cars
cars++;// record amount of cars input into program
cout << "Enter q to quit, or any other key to enter a new car" << endl;
		cin >> userChoice;
		
		

	} while (userChoice != 'q');

rather than use an int to test.

thank you for the suggestion is does make the code more simple or user friendly.
