increment a loop

Question

why is that when you use x++ in the for-loop during incrementing gives a different result unlike using x+1.

Answer 1

x+1 doesn't increase the value of the variable x. ++x does.
So when your loop depends on x increasing, the first method wouldn't give you what you want.

Answer 2

Can you post an example?

Answer 3

x+=1 increments the loop
