Question

I have a string vector and i want to iterate through the vector and then output the contents of that vector one the screen (GUI)

The method used to populate the page is setValue(std::string);

question is, is there a way i could associate a string to the iterator so then i can parse that string into the method and output the contents

So i need to somehow get string str equal that iterator and then i can parse str into the parameter

**std::string str;**
for(it = display.begin(); it < display.end(); it++)
{


}

From what I understand you are asking how to retrieve string from vector<string>::iterator i.

Answer is *i.

Example:

#include <iostream>
#include <string>
#include <vector>
using namespace std;

void foo(string& s)
{
    cout << s << endl; // print argument
}

int main(void)
{
    vector<string> display;
    display.push_back("string1");
    display.push_back("string2");
    display.push_back("string3");

    for (vector<string>::iterator i = display.begin(); i != display.end(); ++i)
    {
        foo(*i);
    }

    return 0;
}
