Can someone explain the difference between x++ and ++x for me in a dumb way? thanks!

I really don't get why you need ++x

x++ use the value stored in x and then do x = x +1 ++x do x = x + 1 and then use the new value stored in x in the rest of the statement... Putting all together in an example: x = 1; y = ++x; // you will have y = 2 and x = 2 z = x++; // now you will have z = 2 and x = 3

x++ is a postfix operator and the value of x is incremented later. ++x is a prefix operator which first increments the value of x by 1. Lets take an example x=5; sum=++x + x++ ;

so its output will be 6 + 6 = 12. so 12 will be stored in sum. Got it !!

x = 1 y = ++x y = (x = x+1) This causes: x = x+1 y = x [x = 2, y = 2] y = x++ y = x, x = x+1 This means: x = 1 y = x x = x+1 [x = 2, y =1]

Explain it to yourself. Enter a value of x then cout it. then use ++x and again cout <<x and for the last time use x++ and cout<<x again.
