Nested Programs Consider the following C function: //represents red/green/blue (rgb) color information for a pixel. struct pixel_24 [ int r, g, b; //applies a noise filter to single pixel in an image. noise is added by /making some pixels contain totally random colors. returns a 1 to //indicate if pixel was randomized, and 0 otherwise. int apply-noise (struct pixel-24[][] data, int x, int y) { int maken ise = rand() % 2; //rand gives a random int n [O, MAX INT] if (make_noise) data [x] [y] . r- data [x] [y] . g- data [x] [y] .b- rand () rand () rand () 256; 256; 256; % Is this function pure?
