Question

I created a struct for Car and now I need to turn it into a class for Car. Below is the code that I wrote for the structure. For the class, we are suppose to make the data in the class Car private, revise the input so the input function will only read the data from the user, and then it will call an additional function named setUpCar which will put the data into the object. Not sure how to change from a struct to a class. The results should look like :

reportingMark SP

carNumber     12345

kind flat

loaded true

destination Salt Lake City

MY CODE THAT I WROTE
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;

struct Car{
string reportingMark;
int carNumber;
string kind;
bool loaded;
string destination;
};

void input(Car *cPtr);
void output(Car *cPtr);

int main(){
Car *cPtr;
cPtr = new Car;
input(cPtr);
output(cPtr);
delete cPtr;
return 0;
}

void input(Car *cPtr){
string rMark;
int len;
cout<<"Enter reporting mark of car: ";
getline(cin, rMark);
len = rMark.length();

while(len>5){
cout<<"Invalid! Enter reporting mark with 5 or less upper case char: ";
getline(cin, rMark);
len = rMark.length();
}
for(int i=0;i<int(rMark.length());i++){
rMark[i] = toupper(rMark[i]);
}
cout<<"Enter car number: ";
cin>>cPtr->carNumber;
cout<<"What kind of car is this(flat,tank,box,other): ";
cin>>cPtr->kind;
cout<<"Is the car loaded(1 if it is, else 0): ";
cin>>cPtr->loaded;
cout<<"Enter the destination: ";
cin.ignore();
getline(cin, cPtr->destination);

cPtr->reportingMark = rMark;
}

void output(Car *cPtr){
string rMark;
cout<<"\nCar Info: \n";
cout<< "ReportingMark: "<< cPtr->reportingMark<<endl;
cout<< "carNumber: "<<cPtr->carNumber<<endl;
cout<< "kind: "<<cPtr->kind<<endl;
cout<< "loaded: "<<cPtr->loaded<<endl;
cout<< "destination: "<<cPtr->destination<<endl;
}

Thanks for the question.

Here is the completed code for this problem. Let me know if you have any doubts or if you need anything to change.

Thank You !!
