afisare vector fara bucla

[Sanda X]

Am o functie care afiseaza la consola stringurile dintr-un vector.

Code: Select all

void afiseaza_vector(vector<string>& v)
{
    int n = v.size();
    for(int i = 0; i < n; i++)
            cout << v[i] << endl;
}

Aceeasi functie scrisa mai elegant cu iteratori

Code: Select all

void afiseaza_vector(vector<string>& v)
{
    vector<string>::const_iterator e = v.end();
    for(vector<string>::iterator i = v.begin(); i < e; ++i)
            cout << *i << endl;
}

As vrea sa o scriu inca si mai frumos fara sa folosesc bucla for sau while.
Se poate?


P.S. Am impresia ca am vazut pe aici sau in alt forum dar acum nu mai gasesc.

Code: Select all

std::copy( v.begin(), v.end(), std::ostream_iterator<std::string>( std::cout, " " ));

[Parametru]

Code: Select all

#include <iostream>
#include <algorithm>
#include <vector>

vector <string> siruri; //sa zicem ca e plin de strings

void buffer(string i)
{
     std::cout << i << std::endl;
}

int main()
{
     for_each(siruri.begin(), siruri.end(), buffer);
     return 0;
}
