#include <vector>
#include <iostream>
using namespace std;
int main()
{
    vector<char> v1 = { size_t(0),0 };
    vector<char*> v2 = { size_t(0),0 };

    cout << v1.size() << endl;// 2
    cout << v2.size() << endl;// 0
    return 0;
}

v1 calls initilizer list ,but v2 calls fill constructor .

is there a way to make v1 overloads fill constructor ,without exiplict calling it (just like how v2 works )?

I do know exiplict calling fill constructor works .

vector<char> v1 = vector<char>(size_t(0), 0);
vector<char> v1(size_t(0), 0);
