This is wrong:
area = double area (double length, double width);
You're returning the value from area(), not declaring it. Just call the function:
area = area(double length, double width);
Your calculation in area(double radius) is incorrect:
area = PI * (radius * 2);
That is calculatin...
Wait a minute. The interviewer, did he look like this guy?
It's bad enough that the interviewer himself has failed this interview,
what if other programmers at this company have "passed" this test?
No. Evaluating the statements 1 == 0 and 2 == 0 should be equally fast. We could imagine poor c...0
In addition to the if(items[r] != null){ pointed out by others, I believe the continue statement in this code is wrong:
for(int r = 0; r < items.length; r++){
if(items[r] != null){
items[r] = new Items(add.getCode(), add.getDescription(), add.getQuantity(),
add.getCos...
So far, I've unlocked one of the secret hats. I'm wondering what other secret hats are out there and how to earn them.
There are two threads, one modifies index variable, another thread test if index was changed does some action. Actually the second thread needs to asses array element by that index.
The part of code is performance critical. My question is what whould be better and faster solution to check index...
I carefully used smart pointer to a void memory leak and dangling pointers. some one says my code has memory leak. is it true? how can i fix it?
#include <iostream>
#include <initializer_list>
#include <memory>
using namespace std;
using Ptr2D = unique_ptr<unique_ptr<int[]>[]>;
using IniList =...54
This post is the result of reading through and following the LOLCODE Specification 1.2, and writing and executing my code on compileonline.com.
My "hello world" was going to be a fizzbuzz. I like it because it nicely illustrates the basics of a language - variables, operators, looping, condition...
Inspired a bit by a previous Brainfuck question and the recent fizzbuzz invasion, I decided to make FizzBuzz in Brainfuck.
The code is entirely my own, except for the inclusion of the Printing a number algorithm that I found on StackOverflow.
My code is divided into several parts.
Setup Const...
I'm pretty new to programming and would like your opinion on my following block of code.
The Objective: Was to see what numbers can be multiplied to equal 100. Example 1 x 1 = 1 //no match. 5 x 20 = 100 //match
PS. the objective (as I'm learning) was only to use an array as I wanted to practice...
Assorted things pop into my head here.
What's wrong with using the String.Substring(Int32) method?
At first glance, I would tend to think your 2nd method would be faster, but they really aren't the same. If input i is greater than test.Length, the 2nd method will throw an exception but the fir...
