Default constructor uses default values if it is required. The sense of "if it is required" is in this sense guys if less argument is given then required then only it is used.
So if no argument is given that it will use default values. Thus default constructor.

Constructor does not contain any argument called default constructor.

The term default in the sense, it takes common value (default) when its not assigned.

If there is any argument type constructor is present, then,
We have to declare constructor function for each and every class type objects passing argument.
In other case if object doesn't pass any value then compiler itself automatically construct a no argument type default constructor.
That's all.

It does not take any arguments or parameters.
#include<iostream.h>
#include<conio.h>
class integer
{
private: //optional
int m,n;
public:
integer() //default consturctor
{
m=0;
n=0;
}
};
void mian()
{
integer i1; //object created
getch();
}

Default constructor we simply means that it has no argument. In this way we pass some argument then it is not default. But when this arguments with default values is called default cons.

Default constructor does not take any argument. its syntax is given as:
sample( )
{
x=0;
y=0;
}
sample( )
{
x=0;
y=0;
}

If it takes parameter it is not default constructor.

If you supply a constructor with parameters then a default will not be created.
