image loads well but i see errors in the output window of vs2012

edit

hi i am a beginner. the following code is used for displaying an image. the program does display an image but i see errors in the output window of vs2012. i want to know if i am doing the right thing here. i use C:\opencv\build\x64\vc11 as the path for opencv and used vs2012.

#include "stdafx.h"
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main( int argc, char** argv )
{
    Mat image;
    image = imread("C:\\jobs.jpg", CV_LOAD_IMAGE_COLOR);   // Read the file
    namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
    imshow( "Display window", image );                   // Show our image inside it.
    waitKey(0);                                          // Wait for a keystroke in the window
    return 0;
}

OUTPUT of output window.
