In C, what is the difference between using ++i and i++, and which should be used in the incrementation block of a for loop?

Understanding the Context
i++ ++i 1 i++ ++i 1 2 i++ ++i .
The way for loop is processed is as follows 1 First, initialization is performed (i=0) 2 the check is performed (i < n) 3 the code in the loop is executed. 4 the value is incremented 5 Repeat steps 2 - 4.
Even though the performance difference is negligible, and optimized out in many cases - please take note that it's still good practice to use ++i instead of i++. There's absolutely no reason not to, and if.
I've seen them both being used in numerous pieces of C# code, and I'd like to know when to use i++ and when to use ++i? (i being a number variable like int, float, double, etc).

One case all these answers fail to mention is what happens when i++ and ++i are used in operations with other numbers. While the whole i++ is before, ++i is after concept is easy to grasp.
They have the same effect on normal web browser rendering engines, but there is a fundamental difference between them. As the author writes in a discussion list post: Think of three different.
