I've found two ways of writing the same program (one that only uses local variables, but no methods other than the main one) and other that uses one instance variable that is used in two methods.
This program aims to simulate the radioactive decay of atoms and uses a random number generator.
Here are the two versions o... |
Basically, I'm performing an if statement on an array based on the returned value
<?php
if($array[1]>10000 AND $array[1]<50000){
$selling = $array[1] - 250;
}
elseif($array[1]>50000 AND $array[1]<100000){
$selling = $array[1] - 500;
}
else{
$selling = $array[1] - 100;
}

Here's my code. Please review it for correctness, readability and efficiency. If you think it can be improved also let me know. This code works fine for positive numbers but doesn't for negative. How can I change it ? Any comments for improvement will be appreciated.
int sum(int a, int b)

int sum = 0;

I feel this is deeply inelegant, but I really want the option of classical inheritance in the future. How could this be written better. FYI animation here is from GSAP if you are curious.

How can I optimize this code to have fewer loops and return values for unit testing?
public class Diamond {
public void DiamondShape(int num) {
for(int ucount=num;ucount>0;ucount--) {
//Loop to print blank space
for(int count_sp=1;count_sp<ucount;count_sp++)
System.out.printf(" ");
//Loop to print *

I wrote a Connect Four game including a AI in Clojure and since I'm rather new to Clojure, some review would be highly appreciated. It can include everything, coding style, simplifications, etc.
But keep in mind the AI is not finished yet, other heuristics will be added in the near future. Currently it only cares abou... |
