What is the difference between i++ and ++i

Answer 1

You can use these in most of languages but not in python

Now you have to know that compiler is compiling from left to right

So if the compiler see ++i it should increase the value of I by 1 then give i

If it see i++ it should give i then increase the value of it
But that will be useful only for complex and store statements like "a++ + ++I - ++w" or "i=u++"
Because there is no difference when you make it in loop

Answer 2

The only difference is the order of operations between the increment of the variable and the value the operator returns. So basically ++i returns the value after it is incremented, while ++i return the value before it is incremented. At the end, in both cases the i will have its value incremented.

Answer 3

If you use it like a single statement
i++;
++i; are the same
But if you use an assignment, b=++i means that you're adding 1 to i and than b=i. b=i++ means that b=i and than you're adding 1 to i. As a result,
i=1
b=++i ->b=i=2
i=1
b=i++ ->b=1 i=2

Answer 4

++i is pre-increment. It will increment i and then return that incremented value by 1.

Post-increment will increment i, but return the original value of i before it was incremented.

i = 5;
j = ++i;
(i is 6, j is 6)

i = 5;
j = i++;
(i is 6, j is 5)

Answer 5

Sorry u cant use i++ and ++i in python
