copy constructor and the definition of it

ndat (13)
I have some exercises to do in my workbook and I'm stuck on one.

it says:

A) Write the function prototype to include the copy constructor for the class dummyClass.

B) Write the definition of the copy constructor for the class dummyClasss


Suppose you have the following definition of a classs

void print();
...
private:
int listLength;
int *list;
double salary;
string name;
}
