C + +: Print container (container) element using the copy function

C + + can use the elements in the Copy function output container (container) to replace the For loop.

Header file:

#include <algorithm>

#include <iterator>

Format:

Std::copy (Cont.begin (), Cont.end (),std::ostream_iterator<type> (Std::cout, ""));

Type is a kind that requires an output format, such as a container that is vector<int>, and the type is int.

#include <iostream >  
#include <algorithm>  
#include <iterator>  
#include <vector>  
      
using namespace Std;  
      
int main (void)  
{  
    Std::vector<int> VI = {1, 2, 3, 4, 5};  
    Std::copy (Vi.begin (), Vi.end (), std::ostream_iterator<int> (Std::cout, ""));  
    Std::cout << Std::endl;  
    return 0;  
}

Output:
