Answer 1

1st code-
x is incremented after the if condition so when x is 4, it is printed then the if condition is checked and the loop breaks.

2nd code-
x is incremented before the if condition so when x is 3, it is printed and then incremented to 4 and then the if condition is checked and the loop breaks.
