problem with constructor

[zareie.ehsan]

I wanna take an 4digit integer value and make the equivalent BCD value. I try this code but it has an error at red line

 

error: 'decimal' : no appropriate default constructor available

it mean the class constructor? is the constructor of  class decimal wrong?

 

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 << in;

      }

     void process3()

     {

         ///

     }

};

Your question is more C++ than SystemC-related. I suggest you to read a good introduction book to C++!

 

Your class decimal is not default constructible, as you have defined a constructor, which takes 4 arguments. Either provide a also default destructor without any arguments or provide default values to all four of its current arguments.

 

In your module seprate_digit, you should also initialize all member variables via the initializer list of the constructor to give names to the ports in, clk, and d as well as maybe initialize you dtmp.
