Expert's answer
A. It's true. for($x = 3; $x<10;$x++) {}. As you can see in brackets we need to specify start value and a terminating condition.
B. It's false. Please, read hint.

C. It's false too, because in third part of definition of the for loop we can define an increment anyway we like. For
examle: $x+=3 or $x*=2;

D. It's true. $x++ equal $x+=1 and equal $x=$x+1.
