unique pointer

[zaahm18]

I made this code here:

#include <functional>
#include <iostream>

#include "to_c_array.h"

void to_c_array(){

}

int main() {

// Please note: this excercise is for educational purposes.
// You should allways use std:: container classes such as std::vector when
// possible.

std::vector<int> v1(10, 1.0);
std::unique_ptr<int[]> p1 = to_c_array(v1);
for (std::size_t i = 0; i < v1.size(); i++)
std::cout << p1[i] << " ";
std::cout << std::endl;

return 0;
}

i want to make a function that will give an output of

1 1 1 1 1 1 1 1 1 1

What does this have to do with "unique pointer"?

What exactly are you trying to do?

Do you realize that your vector has 10 elements with the first initialized to 1 and the rest default initialized?

@jlb, no, they will all be set to 1 (although he should say 1 and not 1.0).
