i got this above example on wikipedia but didn't understand the concept of it can someone explain in some what easy way thanks in advance

Answer 1

if U have written int j=i++; in place of int i=i++;
then the value of i will get incremented

Answer 2

int i=1;i<3;i++;😀

if i<3
you should put "i<3" to make "i++" work.When you describe the condation where "i" is less then "3" then increment get triggred and increse 1 --2
