I have the following code: public class Tests { public static void main(String[] args) throws Exception { int x = 0; while(x<3) { x = x++; System.out.println(x); } } } We know he should have writen just x++ or x=x+1, but on x = x++ it should first attribute x to itself, and later increment … Read more

This question already has answers here: Behaviour of increment and decrement operators in Python (11 answers) Why are there no ++ and – operators in Python? (21 answers) Closed 2 years ago. I’ve always laughed to myself when I’ve looked back at my VB6 days and thought, “What modern language doesn’t allow incrementing with double … Read more
I notice that a pre-increment/decrement operator can be applied on a variable (like ++count). It compiles, but it does not actually change the value of the variable! What is the behavior of the pre-increment/decrement operators (++/–) in Python? Why does Python deviate from the behavior of these operators seen in C/C++? 1Best Answer 11 ++ … Read more
Some Notes: 1- in.nextInt(); reads an integer from the user, blocks until the user enters an integer into the console and presses ENTER. The result integer has to be saved in order to use it later on, and to do so save it into a variable, something like this: int value = in.nextInt(); In your code, you need … Read more
What is the difference between i++ & ++i in a for loop?
Consider this code: “int s = 20; int t = s++ + –s;”. What are the values of s and t?
[c]#include <stdio.h> int main(void) { int i = 0; i = i++ + ++i; printf("%d\n", i); // 3 i = 1; i = (i++); printf("%d\n", i); // 2 Should be 1, no ? volatile int u = 0; u = u++ + ++u; printf("%d\n", u); // 1 u = 1; u = (u++); printf("%d\n", u); … Read more
