Error in program saying "This file requires compiler and library support for the ISO C++ 2011 standard"

This program allows the user to enter expenses for each season and then displays the values and then the total cost at the bottom. It's giving me this error, however, 

In file included from /usr/include/c++/4.8.3/array:35:0,
                 from main.cpp:2:
/usr/include/c++/4.8.3/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
 #error This file requires compiler and library support for the \

How do I fix this?

#include <iostream>
#include <array>
#include <string>

// constant data
const int Seasons = 4;
const std::array<std::string, Seasons> Snames =
    {"Spring", "Summer", "Fall", "Winter"};

// function to modify array object
void fill(std::array<double, Seasons> * pa);
// function that uses array object without modifying it
void show(std::array<double, Seasons> da);

int main()
{
    std::array<double, Seasons> expenses;
    fill(&expenses);
    show(expenses);
    return 0;
}

void fill(std::array<double, Seasons> * pa)
{
    using namespace std;
    for (int i = 0; i < Seasons; i++)
    {
        cout << "Enter " << Snames[i] << " expenses: ";
        cin >> (*pa)[i];
    }
}

void show(std::array<double, Seasons> da)
{
    using namespace std;
    double total = 0.0;
    cout << "\nEXPENSES\n";
    for (int i = 0; i < Seasons; i++)
    {
        cout << Snames[i] << ": $" << da[i] << endl;
        total += da[i];
    }

cout << "Total Expenses: $" << total << endl;
}

Read the error message! You need to compile with -std=c++11 or -std=gnu++11.
