What's up with a++ ++b

Question

What do the ++ stand for and what do they do to the number?

Answer 1

a++ its a post increment, so it will use the acutal value of a, and then increment the value by 1.

++a increments before the operation. so

var a = 1;
print(a++); //this will show 1.now a value its 2.

var b =1;
print (++b); //this will show 2, and the value of b its 2.

Answer 2

a++ is a post increment operator while ++b is a pre increment operator.....
