I am a college student and started my first week of C++ and we were given an assignment to convert a Java program that calculate the interest on a series of loans given the amount of the principal, the annual interest rate, and the number of days in a sentinel loop into C++.
Here is what we were...
I cannot understand why this code doesn't work as I expected, the first function serves for limiting input to 0's and 1's and a total length of 8.
No output in the console after the byte has been entered, also my StrinVar() object appears as PY_VAR0 in the Label.

This is a code in Java to find out the prime factors of a number given in a variable. Is it efficient or where can it be improved?
public class PrimeFactorFinder {
public static void main(String args[]){
long n = 18;
long md = 2;
while(n!=java.lang.Math.sqrt(n)){
if(n%md==0)...
From a React course I'm taking:

I have been using Scala as a means to learn Functional Programming and writing better code. However, I have some questions regarding some exercises or if there's a better way to approach them.
Below are some exercises and my solutions/insights/doubts:

I am implementing tablayout for an activity in my app but for some reason setting icon in for each tab using tabLayout.getTabAt(position).setIcon(icon) is getting small. And also the text is always in uppercase. So I decided to implement custom views for each tab to get the desired result.It did ...
I have written a program to compare two 3D raw data equal or different. But I think the time consuming would be reduced if I use the STL. How to improve the program? The complete and varifiable code is showed as follows:
#include <cstdio>
#include <string>
#include <iostream>
#include <assert.h>...
I have made my first app in Elm, a lookup of Github users.
You type the name of the user into the search bar and the user's username and profile image - which has an anchor linked to their profile - appears below.
Here is my code:

I've written a simple multiple-sender multiple-receiver channel, but I'm unsure if my approach is the best way to do this. I'm not using multi-threaded primitives but instead wrapping around std's builtin sync::mpsc. Performance is fine so far for my use case, but I'm unsure how well this will sc...
Trying to create something really lightweight. Sources are on GitHub.
To create a proxy we need to define an interface first, e.g.:
[Site("https://jsonplaceholder.typicode.com")]
public interface ITypicode

[Get("posts")]
Task<BlogPost[]> GetAsync();
[Get("posts/{0}")]

Challenge
Swap the numbers surrounding the words in sentences.
Specification
The first argument is a path to a file.
The file contains multiple lines.
Each line is a test case represented by a sentence.
Each sentence begins and ends with a number.
Print out the sentence obtained by swapping t...
My solution for an exercise, which requires to translate strings to key presses, on a phone keypad, e.g. to get 'b' the digit '2' needs to be pressed twice.

I've struggled with this for quite some time. Today I finally wrote the following code.
The ViewModel contains an int property which later tells the view how many pages the data has been split into.
The controller splits the data by taking a specified amount of rows and, in the event of paging,...
Please review my Queue implementation and let me know if you have any suggestions. I am not returning an exception for any of the methods defined here. As we know the exception is thrown only for add and remove functions and not for poll or offer functions.

I recently answered a question that had an interesting problem statement (I've slightly modified the wording):
I have an abstract class A which is base for the other classes, let's
say B and C.
Classes B and C should have a handle_input() method, but
argument number and types may var...
I am somewhat new to Java so bear with me.
This bit of code basically creates a rectangle in processing (the user inputs the x-axis, y-axis, length, and height. Note this program is quite buggy.). I would like it to now create triangles, circles, etc. Need advice as to how to tackle that. Thanks....
