//  Use width and bytes_per_pixel as stored in the struct so the function will work even if these parameters change.  
//  This function should return an integer (int, not void).  Check that the name of the struct variable matches
//  the code in your graphics file.

// This function returns the intensity value for the pixel at row, column and color
// It only works if with 24-bit rgb color files
