Why it does no take parameter?

Constructor with no parameters or any number of parameters with default values is called default constructor.
constrctr()
or
constrctr( int a = 1, int b = 2 )
constrctr()
or
constrctr( int a = 1, int b = 2 )

Compiler itself call constructor if no constructor is called with no parameter. Or if user provide constructor with zero parameter then compiler takes it.

Why does not using of parameters ?

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

If it takes parameter it is not default constructor.

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

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.

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();
}

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.
