Question

I need help setting up a default constructor. This is in C++, my program compiles but it doesnt print the correct outpt

#include "vehicle.h"
vehicle::vehicle()
{
//Displays an example; data already stored in the file
vin = "VHR12G3J589R";
make = "Nissan";
model= "Xterra";
year=2016;
price=32800;
}
vehicle::vehicle( string iVin, string iMake, string iModel, int iYear, double iPrice)
{
vin = iVin;
make = iMake;
model = iModel;
year = iYear;
price = iPrice;
} this is what it prints

how do i fix it so that it doesnt repeat the inventory?

thanks
