CS50 "BLUR" PSET 4 - c

Question

when I run make filter it compiles but when I'm running it it does this... helpers.c:104:39: runtime error: -nan is outside the range of representable values of type 'int'
void blur(int height, int width, RGBTRIPLE image[height][width])
{
float red = 0, blue = 0, green = 0;
int average_red[height][width], average_blue[height][width], average_green[height][width];
float count = 0;
// LOOP HEIGHT
for (int i = 0; height > i; i++)
{
// LOOP WIDTH
for (int j = 0; width > j; j++)
{
// LOOP 3x3 PIXELS
for (int x = i - 1; i > x; x++)
{
for (int y = j - 1; j > y; y++)
{
// ONLY ACCEPT PIXELS WITHIN THE IMAGE
if ((x >= 0 && x < height) || (y >= 0 && y < width))
{
red += image[x][y].rgbtRed;
blue += image[x][y].rgbtBlue;
green += image[x][y].rgbtGreen;
count++;
}
}
}
// GET THE AVERAGE
average_red[i][j] = limit(round(red / count));
average_blue[i][j] = limit(round(blue / count));
average_green[i][j] = limit(round(green / count));
// RESET ALL VALUE
red = 0;
blue = 0;
green = 0;
count = 0;
}
}
// LOOP HEIGHT
for (int i = 0; height > i; i++)
{
// LOOP WIDTH
for (int j = 0; width > j; j++)
{
// RETURN THE VALUE BY COLOR TO RESPECTIVE PIXELS
image[i][j].rgbtRed = average_red[i][j];
image[i][j].rgbtBlue = average_blue[i][j];
image[i][j].rgbtGreen = average_green[i][j];
}
}
return;
}

Answer 1

for the inner loops I used
for (int col = i - 1; i + 2 > col; col++)
{
for (int row = j - 1; j + 2 > row; row++)
{
if (col >= 0 && col < height && row >= 0 && row < width)
{
red += image[col][row].rgbtRed;
blue += image[col][row].rgbtBlue;
green += image[col][row].rgbtGreen;
count++;
}
}
}
