Answer 1

Because the while loop run until x is greater then 7, so when x is 8 it will exit the loop, hence it will print 8!
x = 0
loop 1
x = 0 -> x++ -> x = 1
loop 2
x = 1 -> x++ -> x = 2
and so on until
loop 7
x = 6 -> x ++ -> x = 7
now you put the exit condition to x <= 7 so when x is 7 still will run the loop one more time that is:
loop 8
x = 7 -> x++ -> x= 8
now x = 8 so x > 7 so exit loop and output of x is 8!

Answer 2

Because when it reach 7
The condition x<=7 still true, thus x++ expression still executed
