Manash Saikia Because ++x is pre increment so ++x will be 2 and also x will be 2 So 2 == 2 //true (x++ == x) //returns false because of post increment

public class Program { public static void main(String[] args) { int x=1; int y=x;//stores the value of x System. out. print (++x==y);//now x's value is 2,but y's value is remained unaltered } } //Hope this helps you to understand it better

Manash Saikia As x is pre-incremented, it's value becomes 2. Now, x remains 2. So, 2==2 is true.

Because ++x, increment the value of x by 1. And the present value of x(which was 1) is not retained

Pre increment ie (++x) increments x before evaluation while post increment ie (x++) increments x after evaluation.. Therefore it ++x==2 returns false while x++==2 returns true

x++ = x Because x++ will increment value after evaluation so x++ == x is true On the contrary, ++x will increment value before evaluation Then result false if use ++x(2) == 1 Then, ++x can increment value before evaluation so print additional value while increment value☺ Example: cout << ++x << endl;

In such expressions where there is no priority, the phrase is evaluated from the right. In this way, the value x is first equal to two, and then it is compared to the left, which is also two on the left.(because ++x) is prefix operand first add 1 to it then evaluated

Remember: x++ and ++x are different. ++x returns the new value of x, x++ the old. Don't forget ;-)

Because ++x means take your x use it wherever you want after all increase just 1 in your program, java compiler takes x value compares to whatever you wish after all these it increases just 1
