Thread: for_each algorithm

Okay, so my homework assignment states, "use the for_each algorithm to print out the contents of a vector of doubles using the display function." Here is what i have, but how do i get it to send a double to display when all i have is a vector of doubles?

Thanks

Code:

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

using namespace std;

void display (double n);

int main()
{
	vector<double> numbers;
	
	for_each(numbers.begin(), numbers.end(), display(/*what goes here*/));

	return 0;
}

void display (double n)
{
	cout << n << endl;
}

Nothing goes in there. Its assumed the current value in the for_each statement is the parameter of the function:

Code:

for_each(numbers.begin(), numbers.end(), display);

isn't that cute...thank you very much
