what does this mean?

Question

++i

Answer 1

➡++i will increment the value of i, and then return the incremented value.

i = 1;
j = ++i;
(i is 2, j is 2)
➡i++ will increment the value of i, but return the original value that i held before being incremented.

i = 1;
j = i++;
(i is 2, j is 1)

Answer 2

Thank you so much👍🏻
