Your first structure is, does not start or loop infinite. 

for(x=contador_pilotos-1;x<=1;x--)

It can be seen that contador_piloto can be any value, > 1 or < 0. Then:

  • When contador_piloto < 0 x will decrease forever because it will always be less than or equal to 1;
  • When contador_piloto > 2 x will be 2 and when x
