Constructor invocation issue

In this code when try to create dobj4 got compiler error

#include<iostream>
using namespace std;
class mod;
class  name {
    friend mod;
    public:
            name(const char* n) {
                    cout << "1 arg constructor for name\n";
            }
            name() {
                    cout << "no arg constructor for name\n";
            }
            name(const char* n, int i ){
                    cout << "2 arg constructor for name\n";
            }
      };

class mod {
    public:
    mod() {
            cout << "base class constructor invoked\n";
    }
};

struct derived : mod {

    derived(name) {
            cout << "derived constructor invoked\n";
    }
 };

int main() {
    name nobj;
    derived dobj(nobj);

    name nobj1("hello");
    derived dobj1(nobj1);

    derived dobj2("Hi");

    name nobj2("yo", 2);
    derived dobj3(nobj2);

 //      derived dobj4("go", 4);

    return 0;
}

Need to understand how when pass strings invoke constructor for name in case of dobj2 but in case of dobj4 it is causing error How to correct this issue

Thanks in advance
