Instantiating a new object - error - c++

Question

#include <iostream>
using namespace std;
class Vehicle{
protected:
string type;
int wheels;
bool engine; // number of engines in vehicle
public:
Vehicle(string t, int w,bool e):
type(t), wheels(w), engine(e){};
void setType(string t) {type = t;}
void setWheels(int w) {wheels = w;}
void setEngine(int e) {engine = e;} // number of engines, 0 - False.
string getType(){return type;}
int getWheels() {return wheels;}
bool getEngine() {cout << "1 - Has Engine | 0 - No Engine"; return engine;}
};
class Auto:public Vehicle {
private:
string brand;
int year;
public:
Auto(string t, int w, bool e, string b, int y):
Vehicle(t,w,e), brand(b),year(y) {};
void setBrand(string b) {brand = b;}
void setYear(int y) {year = y;}
string getBrand() {return brand;}
int getYear() {return year;}
};
int main()
{
// This first segment of the program demonstrates the relationship
// between the base class and derived class through the use of
// a constructor.
Auto Spider360("Car",4,2,"Ferrari",2000);
cout << "Car type: " << Spider360.getType() << endl;
cout << "Number of wheels: " << Spider360.getWheels() << endl;
cout << " Has Engine: " << Spider360.getEngine() << "\n";
cout << "Brand: " << Spider360.getBrand() << endl;
cout << "Year: " << Spider360.getYear() << "\n\n";
// Now I use member functions directly to assign values to an object
Auto SuperAmerica;
return 0;
}
I am unable to declare the object Auto SuperAmerica; I get the following error: "No matching function call for Auto::Auto()" and for SuperAmerica, i do not want to use a constructor to set the values, I want to use my Set functions.

Answer 1

The error of
"No matching function call for Auto::Auto()"
means that you cannot instantiate the class in the way you wanted. If you want to create the object and then initialize its members later, using setters, then use a default constructor.
