C/C++ Source Codes

declare only one constructor and give it default parameters wherever possible instead of overloading constructors

//It is a good practice to try not to overload the constructors.
//Best is to declare only one constructor and give it default parameters
//wherever possible :
#include <iostream.h>
class vector
{
public:
double x;
double y;
vector (double a = 0, double b = 0)
{

x = a;
y = b;
}
};
void main ()
{
vector k;
cout << "vector k : " << k.x << ", " << k.y << endl << endl;
vector m (45, 2);
cout << "vector m : " << m.x << ", " << m.y << endl << endl;
vector p (3);
cout << "vector p : " << p.x << ", " << p.y << endl << endl;
}
