TCanvas Not Displaying Microsoft Visual Studio 2013

ROOT
1

Hello,
I am a new ROOT and c++ user. I am trying use ROOT in Microsoft Visual Studio 2013. I have gone through most of the steps I think are necessary to be successful in my endeavors. However, when I try the example code below, I expect a TCanvas to be generated in a new window, but no such window is generated.

#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include "TFile.h"
#include "TF1.h"
#include "TROOT.h"
#include "TH1.h"
#include "TGraph.h"
#include "TMath.h"
#include "TCanvas.h"

int main(int argc, const char* argv[])
{
	TF1 *fa1 = new TF1("fa1", "sin(x)/x", 0, 10);
	fa1->Draw();
	
	system("PAUSE");
	return 0;
}

When I run the .exe file, the only output is:

Info in TCanvas::MakeDefCanvas: created default TCanvas with name c1
Press any key to continue . . .

Please let me know what I can do to see the plot, or if you need any other information from me. Thank you.

// This small demo shows the traditional "Hello World". Its main use is
// to show how to use ROOT graphics and how to enter the eventloop to
// be able to interact with the graphics.

#include "TApplication.h"
#include "TCanvas.h"
#include "TLine.h"
#include "TPaveLabel.h"
#include "TGraph.h"


int main(int argc, char **argv)
{
   TApplication theApp("App", &argc, argv);

   TCanvas *c = new TCanvas("c", "The Hello Canvas", 400, 400);
   c->Connect("Closed()", "TApplication", &theApp, "Terminate()");


   int x[10], y[10]; int i;

   for(i = 0; i < 10; i++) {
      x[i] = 10*i;
      y[i] = i;
   }

   TGraph *gr = new TGraph(10,x,y);
   gr->SetLineColor(2);
   gr->SetLineWidth(1);
   gr->SetMarkerColor(4);
   gr->SetMarkerStyle(1);
   gr->Draw("AL");

   TPaveLabel *hello = new TPaveLabel(10.,8.,90.,9.,"Hello World");
   hello->Draw();
   TPaveLabel *quit = new TPaveLabel(10.,6.,90.,7.,"Close via menu File/Quit");
   quit->Draw();
   c->Modified();
   c->Update();

   theApp.Run();
   return 0;
}

It works. Thank you.
