The following code snippet (where pixel is an alias for a standard type such as char or int) is used to allocate memory so that image can be used as a 2D array (pixels addressed by image[10] [5] for example). The array has dimensions rows by cols. image = (pixel **) malloc(rows*sizeof(pixel *)): image[0]= (pixel *) malloc(rows*cols*sizeof(pixel)): for (i=1: i
