What is the difference between prefix and postfix operators? There is a big difference between postfix and prefix versions of ++ In the prefix version (i e , ++i), the value of i is incremented, and the value of the expression is the new value of i In the postfix version (i e , i++), the value of i is incremented, but the value of the expression is the original value of i Let's analyze the following code line by line:
