problem with constructor

[zareie.ehsan]

I wanna take a  4 digit integer value as an input an make an BCD equivalent, I tried this code but it has error: error at red line

error: 'decimal' : no appropriate default constructor available

 

it mean the class constructor? is the constructor of  class decimal wrong? plz help me

 

class decimal

{

public:

sc_int<4> dec0;

sc_int<4> dec1;

sc_int<4> dec2;

sc_int<4> dec3;

decimal(sc_int<4> d0,sc_int<4> d1,sc_int<4> d2,sc_int<4> d3)

   {

       dec3=d3;

       dec2=d2;

       dec1=d1;

       dec0=d0;

   }

}

 

SC_MODULE (seprate_digit)

{

    sc_in <sc_int<16>> in;

    sc_in <bool> clk;

    sc_out <decimal> d;

    decimal dtmp;

 

    SC_CTOR (seprate_digit)

    {

         SC_METHOD(process3);

         sensitive << clk.pos();

    }

   void process3()

   {

      /////

   }

};
