What is the difference between i++ and ++i in C#


Share with WhatsApp


In this post I will share some information about incremental operator ++ of C#. In many interviews this question has been already asked and still it is one of the favorite question for some of the interviewers i.e. What is the difference between i++ and ++I in C#?

So let’s check what the difference is.

In both the cases value of “i” gets incremented but the difference is i++ - It’s a type of post increment. When you write i++ it means “give me the value of i and then increment its value”, on the other hand ++i means “increment the value of i and then give me the updated value”.

Let’s understand using some example.

If you write a code like below.

int i = 2;

int j= 2;

int k = i++;

int l = ++j;

In above case, at the end, values of i,j,k and l will be like following

i = 3

j = 3

k =2

l = 3

So by above example you can easily understand how pre increment and post increment works.

If not and having some queries do share in comment section below. If you have something positive to add this short but useful post then do share that too. Thanks.
