If anyone can help me understand what is the benefit between writing Prefix to "change" the value of both 'x' and 'y' (1/2)

(2/2) from say 25 to 26 and just writing a line like int x = 26, y=26;

x++ or ++x is very useful in loops or counting things example: (pseudo code) 1)int x = 0, counter = 0; 2)accept input from user into array 3)for(int i = 0; i < inputArray.length; i++){ if(inputArray[i] is valid){ counter++; } } 4)print(“there is” + counter + “of valid input”);

In more complex software you dont want to know what value your variables have so you just increment by using x++;

-It will help you to increase the value of your variable.. -It is useful in loops -it uses the same variable and increase/decrease its value. -No new variable required to assign new value.
