C problem how many times does the default constructor and co

C++ problem:

how many times does the default constructor and copy constructor being invoked?

int pob2(dice d1, dice d2, dice &d3){

dice a(d1);

dice b(d2);

dice c=d3;

int result =(a+b);

result = result +c.getvalue();

return result;

}

int main()

{

dice one, two(6), three;

cout<<p2(one, two, three)<<endl;

return 0;

}

Solution

Answer:

default constructor is being invoked 2 times. while creating these dice objects \"one\", \"three\", default constructor will invoke.

copy constructor is being invoked 5 times.

while passing dice objects \"one\" and \"three\" to function p2(), copy constructor will invoke 2 times and inside p2() function while creating \"a\", \"b\", \"c\" dice objects, another 3 times copy contructor will invoke. so totally it will invke 5 times.
