Can we have more than one constructors in a class?

Answer 1

You can have many, as long as they don't have the same parameters and in the same order in the signature.

I think there are three known types:
° Default (in which you inicialize everything with a default value )
°Common (some are passed through parameters and others as in Default)
° Complete (of full I guess, I learned in Spanish) in which you don't inicialize anything with a default value, you use the parameters.

Answer 2

We can have more than one constructor in a class, as long as each has a different list of arguments.

#include<iostream>
using namespace std;

class Point
{
private:
int x, y;
public:
// Two constructors
Point(int x1, int y1) { x = x1; y = y1; }
Point() {x = 0; y = 0; }

int getX() { return x; }
int getY() { return y; }
};

int main()
{
Point p1(10, 15); // first constructor is called here
Point p2; // Second constructor is called here

// Let us access values assigned by constructors
cout << "p1.x = " << p1.getX() << ", p1.y = " << p1.getY();
cout << "\np2.x = " << p2.getX() << ", p2.y = " << p2.getY();

return 0;
}

output :

p1.x = 10, p1.y = 15
p2.x = 0, p2.y = 0

Answer 3

Yes
Your default and non default constructors.
