Thanks,

Hi prasath,

The concept of "passing by reference" itself is alien to C.
And the post/pre-increment are not functions, they are operators. So, both of them have to increment whatever value is sent to them.
If you understand the concept of passing by value, you will know that the value of the variable sent to the function will remain unchanged.
As you are thinking if post increment passes the argument as "pass by value", then the value should not change at all. But, on the contrary, it also changes the value of the argument!

Hope informative to you.
