Question

Consider the following code snippet: public class Vehicle { private String type; private int numAxles; public Vehicle(String vehicleType, int VehicleAxles) { . . . } public Vehicle(String vehicleType) { . . . } } What is wrong with this code?

Answer 1

Answer:

class Vehicle

{

private:             //should be declared once

string type;      //should be small as C++ is case sensitive

int numAxles;  

public:             //should be declared once

Vehicle ( string vehicleTypes, int VehicleAxles);    \\s should be small as C++ is        case sensitive and it is a parametarised constructor  

Vehicle (string vehicleType, int b);    //s should be small as C++ is case sensitive and now this is also a parametarised constructor

};        //a class ends with }: not with }

Explanation:

There are two constructors in this piece of code. The first constructor was parametrised while the second only had one argument. The second constructor should have 2 arguments like the first construtor or it should be empty. I've passed another argument to the second constructor. Moreover, the class ends with }; not with } and as we know C++ is case sensitive language so, declare the reserved keywords with small letters.
