Could you please tell me how to arrange my code so that the invalid statement like in my displayed output will only show up if some enters a wrong character.
Here is my code:
#include <iostream>
#include <fstream>
#include <iomanip>
#include <cmath>
using namespace std;
int main()
{
//(1) Declare some variables to work with
char fare;
char choice='Y';
int hrIn, minIn, hrOut, minOut;
int hours;
int minutes;
int total_minutes;
int additionalTime;
double cost;
double charge;
while(choice=='Y'||choice=='y'){
//(2) Output read info and user message
cout << "\nThis program will calculate a single, couple, or group "
<< "\nfare amount which is then owed by the customer for the trip.\n"
<< "\nTo calculate a single fare amount, input S (or s)"
<< "\nTo calculate a couple fare amount, input C (or c)"
<< " \n\nInput S, C" ";
cin >> fare;
// end of description

*Output:
This program will calculate a single, couple, or group
fare amount which is then owed by the customer for the trip.
To calculate a single fare amount, input S (or s)
To calculate a couple fare amount, input C (or c)
To calculate a group fare amount, input G (or g)
Input S, C, or G: s
What hour did the single customer depart? 9
What minute did the single customer depart? 25
You entered for departure: 9:25
What hour did the single customer arrive? 10
What minute did the single customer arrive? 30
You entered for arrival: 10:30
A rickshaw departed at 9:25 and arrived at 10:30 with a single customer.
The single customer arrived in 1 hour(s) and 5 minute(s),
or in a total of 65 minutes.
The single customer will be charged for 35 extra minute(s).
The single customer will pay $59.50 dollars.
The character that you have entered was invalid! Please try again!
Would you like to perform another calculation (Y/N)?
