using namespace std;
int main()
{
	int i=1;

Hello all,I am new to c++,I just have a small query when i tried to cout the result it giving 4 and 3.But actually it has to give 3 and 3 right ?

Pre-increment increases the value first and then returns the result.
Post-increment increases the value, but returns a copy of the original value.

ya as you said,here in case of i =3 because j is increased to 3 as original value of j is 2.And i=3 because the copy of original value is 3 right ? please help me.
