Collision Detection

C/C++
A snippet of code used to detect collision between a missile and an enemy
for(l = 0; l<150; l++){
  for(m = 0; m<num_aliens; m++){
	  if(((Missile1[l].y -13) <  Enemy1[m].y)){
		 if(((Missile1[l].y-13) > (Enemy1[m].y -10))){
		  if((Missile1[l].x) > Enemy1[m].x & Missile1[l].x < (Enemy1[m].x + 16)){
			 if(Missile1[l].x != -1 & Missile1[l].y != -1 & Enemy1[m].x != -1 & Enemy1[m].y != -1){
				  DisableInterrupts();
					Missile1[l].x = -1;
					Missile1[l].y = -1;
					Enemy1[m].x = -1;
					Enemy1[m].y = -1;
				  player1.score++;
