c - Using a for loop to display sprites randomly? -

so im trying write code displays 5 sprites randomly on lcd screen on microprocessor (teensy). i've taken care of simulating randomness seeding on button press;

void seedwithbuttonpress() { ddrb |= 0b00001100; unsigned int seed = 0; while (!((pinb >> pb0) & 1)) {     seed++; } srand(seed); } 

as far initilizing , drawing sprites screen, current attempt has failed.

void create_sprites(sprite sprites[]) {  byte bitmap [] = { byte( 11100000 ), byte( 01000000 ), byte( 11100000 ) };  (int = 0; < 8; i++) {     sprite * sprites = &sprites[i];     init_sprite(sprites, rand()%76, rand()%42, 3, 3, bitmap);     }  setup_sprites(); }   void setup_sprites(sprite * sprites) { ( int = 0; < 10; i++) {     draw_sprite( sprites + );     refresh(); } } 

how go this?
