Thread: Vector pair

Im trying to create a vector of pairs, im kinda stuck here.

Code:

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

typedef pair<string, int> MyPair;

int main ()
{
    vector<string> first;
    vector<int> second;
    vector<MyPair>::iterator it;
    vector<MyPair> vPair;
    const char* names[] = { "Sneezy","Dopey",
                            "Sleepy", "Doc",
                            "Happy", "Bashful", "Grumpy"
                          };

    for (int i=0; i<7; i++) first.push_back (names[i]);
    for (int i=0; i<7; i++) second.push_back (i*10);

    for (int i=0; i<7; i++)
        vPair.push_back(make_pair<first[i], second[i]>);

    for (it=first.begin(); it!=first.end(); ++it)
        cout << " " << *it;

    cout << endl;
    return 0;
}

Firstly, make_pair would be called like this:

Code:

vPair.push_back(make_pair(first[i], second[i]));

Secondly, are you trying to loop over the vector of strings or vector of pairs here:

Code:

for (it=first.begin(); it!=first.end(); ++it)

If it's the latter than pair doesn't overload operator<<, you'll need to output pair.first and pair.second separately.

Thank you Tabstop and Anon, i managed to work it out.
