What is different between i++ and ++i ?

Answer 1

I++ (postfix)means first use then increase and ++I (Prefix)means first increase and then use

Answer 2

Post-Increment (i++) : Value is first used for computing the result and then incremented.

Pre-Increment (++i): Value is incremented first and then result is computed.

Answer 3

I++ and ++I are increment operators.

I++ is post increment.

It means first it assign a value to variable then it will increment.

For Example,

i=1;
J= i++;
J=i+1;
So
J= i => j=1 then
J= 1+1= 2;
So finally the value of J = 2;

++I is pre increment operators.

It means first increment then assign to value.

J= ++i;
J=1+i;

i=1;
So, J=1+i=> J= 1+1= 2;

Answer 5

The other answers about increments are great. You still also need to understand both decrements, too. i-- and --i. So...

i++

If i == 1, this operator will calculate the line where it was used, then set i=2.

++i

If i == 1, this operator will set i=2, then calculate the line where it was used.

i--

If i == 1, this operator will calculate the line where it was used, then set i=0.

--i

If i == 1, this operator will set i=0, then calculate the line where it was used.
