Constructor Overloading

Since Constructor is a special member function, Constructors can also be overloaded like functions.

Constructor overloading is similar to function overloading.

A class defined with multiple constructors is called constructor overloading.

Overloaded constructors have the same name, they differ in their signature, that is, number of arguments and sequence of arguments passed.

A constructor is called depending upon the number and type of arguments passed.

Example. //Demonstration on constructor overloading

#include<iostream.h>

#include<conio.h>

class sample

{

private:

int a;

public:

sample()

{

cout<<"\nInside default constructor...";

a=0;

}

sample(int x)

{

cout<<"\nInside parameterized constructor...";

a=x;

}

void show()

{

cout<<"\n a= "<<a;

}

};

void main()

{

clrscr();

sample s1;

s1.show();

sample s2(10);

s2.show();

getch();

}
