[DUPLICATE] What is difference between i++ and ++i

Answer 1

post increment = x++
pre increment = ++x

int x = 5;
int y = x++;

Now x is 6 and y is 5.

int x = 5;
int y = ++x;

Now both x and y are 6.

The pre-increment first do increase/decrease of the variable and next some operetions.
The post-increment do some operations first and at the end increase variable.

Answer 2

a = i++ means variable a is set to the value of i, then value of i is added by 1, so a!=i

a = ++i means value of i is added by 1, then a is set to value of i, so a==i

Answer 3

When using post-increment (i++), the expression is evaluated first and then the value of the variable "i" gets incremented by 1.
In case of pre-increment (++i), the value of variable "i" is first raised by 1, and then the given expression is evaluated.

Answer 4

i++ is called post increment.... Current value of i is used to evaluate the statement and then increment value of i by 1.

++i is pre increment... Here value of i incremented by 1 and incremented value is used in the given statement.
Int i = 5;
Print i++
5

Print ++i
6
