for_each(c++11)

template<class InputIterator, class Function>

Function for_each(InputIterator first, InputIterator last, Function fn)
{

while (first!=last) {

fn (*first);

++first;

}

return fn;
// or, since C++11: return move(fn);
}

 

// for_each example
#include <iostream>
// std::cout
#include <algorithm>
// std::for_each
#include <vector>
// std::vector

void myfunction (int i) {
// function:

std::cout << ' ' << i;
}

struct myclass {
// function object type:

void operator() (int i) {std::cout << ' ' << i;}
} myobject;

int main () {

std::vector<int> myvector;

myvector.push_back(10);

myvector.push_back(20);

myvector.push_back(30);


std::cout << "myvector contains:";

for_each (myvector.begin(), myvector.end(), myfunction);

std::cout << 'n';


// or:

std::cout << "myvector contains:";

for_each (myvector.begin(), myvector.end(), myobject);

std::cout << 'n';


return 0;
}

 

Output:

myvector contains: 10 20 30
myvector contains: 10 20 30
