| Why does this code won't work? It displays 0 Posted: 21 Mar 2021 08:16 AM PDT whenever I compile it displays 0 instead of 11. what is wrong this code? I used a function add. I notice that this works when I'm using an array string. #include <stdio.h> #include <stdlib.h> void add(int result, int a, int b); int main(void) { int num1 = 5; int num2 = 6; int result1 = 0; add(result1, num1, num2); printf("%d", result1); return 0; } void add(int result, int a, int b) { result = a + b; }

| Need to write a python program to extract questions and answers and create a csv file Posted: 21 Mar 2021 08:15 AM PDT I have a text file consist of questions and answers Below is the example of text file 1. What is namespace in Python? Answer: In Python, every name introduced has a place where resides and can be found. This space is known as a namespace. It is an address location where a variable name is mapped to the object placed. Whenever the variable is searched out, this address location will be searched, to get the corresponding object. 2. How do you make 3D plots/visualizations using NumPy/SciPy? Answer: Like 2D plotting, 3D graphics is beyond the scope of NumPy and SciPy, but just as in the 2D case, packages exist that integrate with NumPy. Matplotlib provides basic 3D plotting in the mplot3d subpackage, whereas Mayavi provides a wide range of high-quality 3D visualization features, utilizing the powerful VTK engine. 3. Differentiate between .py and .pyc files? Answer: Both .py and .pyc files hold the byte code. ".pyc" is a compiled version of Python file. This file is automatically generated by Python to improve performance. The .pyc file is having byte code which is platform independent and can be executed on any operating system that supports .pyc format.

| Register route 404 not found Posted: 21 Mar 2021 08:18 AM PDT I am building a register page and when I submit the I am getting a 404 not found. I am using react and express and I think the front end is good. I am missing some back end or have the wrong url for my post request: axios.post('http://localhost:3000/auth'. Would appreciate some advice if anyone can see what I have wrong. const handleSubmit = event => { event.preventDefault(); const user = { username: username, password: password, } axios.post('http://localhost:5000/', { user }) .then(res=>{ console.log(res); console.log(res.data); }) }
This is the registerPost function for my route. export const registerPost = async (req, res) => { const {username, password} = req.body; const newUser = new User({username, password}); try { await newUser.save(); console.log(newUser); res.status(201).json(newUser); } catch (error) { res.status(409).json({ message: error.message }); } }
These are the routes. import express from 'express'; import { getPosts } from '../controllers/posts.js' import { createPost, updatePost, deletePost, registerPost } from '../controllers/posts.js' const router = express.Router(); router.get('/', getPosts); router.post('/', createPost); router.patch('/:id', updatePost); router.delete('/:id', deletePost); router.post('/auth', registerPost); export default router;

| PHP Merge with separators Posted: 21 Mar 2021 08:16 AM PDT I am trying to merge two strings in a specific way. Essentially I need to merge the first two strings into a third with a pipe symbol between them then separated by commas: $merge1 = "id1,id2,id3" $merge2 = "data1,data2,data3"
Those two would become: $merged = "id1|data1,id2|data2,id3|data3"
I hope this makes sense?  |

| How to centre text vertically AND horizontally in a div whilst also flowing around an image who's size can vary Posted: 21 Mar 2021 08:16 AM PDT Is it possible to centre text using CSS horizontally and vertically within a div that also has a variable size image (which should always be right-aligned)? For example, this is to style the "header" of a sports league table display - with the header basically consisting of the league name (the text) and optionally a league logo (the image). The image width and height could be variable, depending on the logo image used. .lbo_header_logo { border: 1px solid #31639C; float: right; margin-left: 20px; vertical-align: middle; } .lbo_header_title { padding: 5px; background-color: #ddeeff; border: 1px solid #31639C; min-width: 550px; vertical-align: middle; width: 50%; } .lbo_header_name { color: black; font-size: 16px; font-weight: bold; overflow: hidden; text-align: center; vertical-align: middle; }
<html> <head> <title>Test!!</title> </head> <body> <div class="lbo_header_title"> <div class="lbo_header_name">League 1<IMG class="lbo_header_logo" src="images/logo1.gif" width="70" height="30"></div> </div> <div class="lbo_header_title"> <div class="lbo_header_name">League 2<IMG class="lbo_header_logo" src="images/logo2.gif" width="30" height="70"></div> </div> </body> </html>
I think I've managed to get the text centred horizontally (as per the example), but have struggled vertically! I've tried all manner of hacks, such as the line-height trick - but this doesn't work for me as the height of the image is unknown. I guess I'd be looking for some sort of solution that uses a max value for the image height, as ultimately I'd want to limit the logo to a sensible height/width anyway (i.e. to avoid them uploading a stupidly long/wide image that screws up the display anyway!).  |
| x86 Assembly: int13h seems to not load program Posted: 21 Mar 2021 08:16 AM PDT Recently I've been trying to make an operating system for fun and I started with the bootloader. First I'd like to start by saying I asked another question about the same side effect (program not running) yesterday, but it turns out the cause is probably different than what I first thought. So, this is the bootloader code: start: jmp boot boot: cli ; Disable interrupts cld ; Clear direction flags mov al, 2 ; Read 2 sectors mov ch, 0 ; Track 0 mov cl, 2 ; Read 2nd sector (1st sector is bootloader) mov dh, 0 ; Head number mov dl, 0 ; Drive number (0 = floppy drive) ; Specify memory address to read floppy to mov cx, 0x5000 mov bx, cx mov es, bx xor bx, bx mov ah, 0x2 ; INT 0x13 with AH=0x2 means read sector int 0x13 ; Call BIOS to read sector jmp cx ; Jump to sector ; Must be 512 bytes times 510 - ($-$$) db 0 dw 0xAA55 ; Boot Signature
However, the sample program I have never runs. Running this on QEMU, I previously thought the issue was that the jmp goes to the wrong address, but now after getting a memory dump and doing some more debugging I see that the jmp happens and it goes to the correct address, but address 0x5000 is all zeroes and has absolutely nothing, nor does anything near it. Could this be a problem with GDB/QEMU not being good with segmentation or real mode? I read something about that. Or perhaps I am using int 0x13 wrong? Perhaps segmentation doesn't work like this? Since I use the value of a register for the address to start storing the data into and then also use it to jump there, shouldn't it be the exact same address thus should be correct? I couldn't find anything on the internet helping with this and I'm totally confused. Please enlighten me. All help is appreciated, thank you!  |
| CHARTJS baar chart not showing Posted: 21 Mar 2021 08:17 AM PDT i have this js code for a bar chart and i use python data for the yaxis this is my js code : <div class="btcprices-chart"> <canvas id="myChart3"></canvas> <script> var ctx = document.getElementById('myChart3').getContext('2d'); var chart = new Chart(ctx, { // The type of chart we want to create type: 'bar', // The data for our dataset data: { labels: ["day1", "day2", "day3", "day4"], datasets: [{ label: 'bitcoin brices per day', backgroundColor: 'rgb(66, 103, 178, 0.6)', borderColor: 'rgb(75, 79, 220))', borderWidth: 2, data: {{ btcprices|safe }} }] }, // Configuration options go here options: { title: { display: true, text: 'bitcoin brices per day' } } }); </script> </div>
i have another chart but with nother data values : data=[626830186, 1055315163, 64138356, 314568549] and for this chart btcprices=[59014, 57922, 58243, 58376] (that's what shows in the console after i runserver because i have pprint(data) and print(btcprices) in my views.py) in data : {{ btcprices|safe }} , it works when i replace it by {{ data[safe }} but when i put in data : {{ btcprices|safe }} it shows this : weird bar chart output ps : whn i call the 2 variables data and btcprices in th html just to print them on the web page like : {{data}} and {{btcprices}} only data shows !!!! this is my views.py by the way : context = { "data": data, "btcprices": btcprices, } return render(request, "index.html", context)

| How to run Angular e2e with SSL enabled? Posted: 21 Mar 2021 08:17 AM PDT I have a pretty simple Angular sample project, with some end to end tests. I'm testing OAuth2 and OIDC flows in my end to end tests, and browsers behave quite differently with or without SSL/TLS enabled. So I'd like to run my end to end tests with SSL turned on locally too. I now run my tests with the Angular CLI like this: ng e2e
I tried to run it like this: ng e2e --ssl=true
Although the --ssl=true option does work for ng serve, it does not work for ng e2e giving me: Unknown option: '--ssl' Is there a way or workaround to make the Angular CLI based Protractor / Selenium tests run with SSL?  |

| How to let Idea comment my comments in xml right? Posted: 21 Mar 2021 08:16 AM PDT I am using Idea to manage my spring project. It uses mybatis for ORM. When I was working on a mapper XML file, I added some comments, marked them, and hit ctrl + / to comment that line, the comments are commentted with a # sign at the start of line. ... <if test="cm.timeTipEnd != null"> <![CDATA[and r.create_time <= #{cm.timeTipEnd}]]> </if> # My comments explaining the next if below <if test="cm.writersId != null and cm.writersId != ''"> ...
Then I tried the block comment hotkey, ctrl + shift + /, and /* */ shows up! <if test="cm.timeTipEnd != null"> <![CDATA[and r.create_time <= #{cm.timeTipEnd}]]> </if> /*My comments explaining the next if below*/ <if test="cm.writersId != null and cm.writersId != ''"> ...
What I want is <!--My comments explaining the next if below-->, though. Is there a way to fix this? I noticed if I select some xml tags and hit the comment key, it would be comment right. However, my comments don't need xml tags. Edit: a gif demonstration of me adding line comment and block comment to a select statement in mybatis mapper(not working), and doing the same thing to a select tag(working)  My idea log file: download link  |
