Windows使用graphics.h错误

Question

I am trying to use the graphics.h library for C/C++ to get pixel values from some images. The program compiles without any errors or warnings but when I try to execute it, a window is opened with the following message: "version2.exe has encountered a problem and needs to close. We are sorry for the inconvenient".

My code:

#include <graphics.h>
#include <stdio.h>

/* Macros to set important values for
*  size and number of images
*/
#define IMAGES 9
#define WIDTH 200
#define HEIGTH 225

/* Receives the image number and load it using
 * readimagefile() function from BGI libary.
 */
void loadImage(int imageNumber);

int main(int argc, char const *argv[])
{
  int row, column, image;
  int red[HEIGTH][WIDTH][IMAGES], green[HEIGTH][WIDTH][IMAGES], blue[HEIGTH][WIDTH][IMAGES];
  int pixelValue;
  int finalWindow, currentWindow;


  for (image = 0; image < IMAGES; ++image)
  {
    currentWindow = initwindow(WIDTH, HEIGTH, "current"); // creates window to receive image
    setcurrentwindow(currentWindow); // set recent window as the current window
    loadImage(image);

    for (row = 0; row < HEIGTH; ++row)
    {
      for (column = 0; column < WIDTH; ++column)
      {
          pixelValue = getpixel(row, column);
          green[column][row][image] = GREEN_VALUE(pixelValue);
          red[column][row][image] = RED_VALUE(pixelValue);
          blue[column][row][image]= BLUE_VALUE(pixelValue);
      }
    }
  }

  getch();

  return 0;

}

void loadImage(int imageNumber)
{
 char str[5];
 sprintf(str, "%i.jpg", imageNumber);
 readimagefile(str, 0, 0, WIDTH, HEIGTH);
}

Answer 1

graphics.h refers to the MS DOS graphics library "BGI", by Borland. It is only supported by Borland DOS compilers and cannot get ported to another OS, save for the old Windows versions like Windows 95/98 that still supported DOS.

Answer 2

graphics.h是1990年代Borlando编译器（例如turbo c）使用的一个库，现在该库已经非常过时并且不受主要编译器的支持。代替graphics.h，您可以使用您的editor.graphic定义的图形库函数。函数因编译器而异，因为它们不是标准c语言的一部分，它们的实现方式由不同的编译器不同
