What is the difference between i++ and ++i

Question

please answer, i'm having test tomorrow

Answer 1

In the beginning.beginner will think like what @Ryan Ward said
but the truth is

++i will do increment first then return the i

i++ will make copy form of i then do increment after there return that copy form

which mean that ++i is faster than i++

Answer 4

one increments before using the value and the other increments after using the variable. Google prefix and postfix if you need more info.

Answer 5

i++ : "i" value is read by the compiler and increments the value by 1, like i=I+1.
++i : first it increments the value by 1 and uses the "i" value, like 1+i= i.
