return vector<string> function

[quizkiwi]

How do i call that function so that i can use the vector in main?

thanks!

vector<string> function();

int main()
{
    //what goes here?
}

vector<string> function()
{
    vector<string> s(3);
    s[0] = "one";
    s[1] = "two";
    s[2] = "three";

    return s;
}

int main()
{
    //what goes here?
    vector< string > vec( function() );
}

The return Type of the function is a vector<string> so it has to return a vector of strings... all you do is create another vector<string> in main and asign it the function.

Just as Antigloss showed you

You have a variety of options depending on your knowledge base and needs. Antigloss' version uses the copy constructor of vectors to transfer information from
from function() to main(). However, you could use the assignment operator:

vector<string> function();
 
int main()
{
	vector<string> vec;
	vec = function();
}
 
vector<string> function()
{
	vector<string> s(3);
	s[0] = "one";
	s[1] = "two";
	s[2] = "three";
 
	return s;
}

or you could use a single vector passed back and forth by reference:

void function(vector<string> &);
 
int main()
{
	vector<string> s(3);
	function(s);
}
 
void function(vector<string> & rS)
{
	rS[0] = "one";
	rS[1] = "two";
	rS[2] = "three";
}

thanks, i could not figure out how to assign that vector in the main.
