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 .
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.
[] sick i [i] seek ee 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.
Key Insights
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.
for(int i=array.length; i<0; --i) Maybe someone can explain me the difference with i-- ? i guess it's something like the moment when i is decremented ?
