Do you have to pay for this app or is it completey free? Because this is amazing, I just started an excelerated class on C#, and this app has helped me more than the book for my class!

Why are virtual functions needed? if you had a base class with an attack function and you had a derived class (n) with an attack function could you not just use n.attack(); to access that function?

in the following why the code num=num+1;can't be applied just after while loop in the beginning of curly braces? #include <iostream> using namespace std; int main() { int num = 1; while (num < 6) { cout << "Number: " << num << endl; num = num + 1; } return 0; }

Function modulo is easy. For example 14 modulo 3. We must find number, which is smaller than 14 (<14), can be divided ( /) and it will be rational number (1, 2, 3... Not numbers like 3,123). It's 12 (12/3=4). Then we just subtract 14 and 12 (14-12). It's 2.

* represents multiplication but why is it written like f*, this makes it look like f has an exponent (in module 6 question no 6) it would have made sense if f*I not f*=I that just complicated things for me.

just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

When using Scanner is there a way to display at the top of the response entry box? Currently in the Code Playground it just displays "it looks like your application needs some input" but when requesting multiple input need a way to tell what is needed.

Just a friendly suggestion: I downloaded the Python Console on Google Play Store, so when I have issues in the app that may be bug related, I can try it in the console. I often can figure it out there more easily. May not be helpful to some, but was for me.

So I'm trying to add a picture to my website atm and I'm new to this so I got this app. The image is a .pgn and even if I say <img src="thename.png" /> it doesn't work on the site. I've updated it from Filezilla obviously but it just shows a little jpg logo and doesn't display my pic. What am I doing wrong?

Why is it that this app is no longer explanatory as it used to be? In css3 tutorials, the entire css input is not shown, just the new line of code. And the corresponding html code isn't shown and explained as it used to be in html and css tutorials.

Hi I've created a simple submission form but when I enter the required argument it doesn't force the user to fill in the mission fields instead it just reloads the page when submit it press. Is this because the backend hasn't yet been designed? Thanks you in advanced!

what have i to do, if i want that the program always writes for example : 0+1 1+2 3+3 6+4 10+5 15+6 ... because now it just writes 1 3 6 10 15 ... and maybe if it works, can i make then 0+1=1 1+2=3 3+3=6 6+4=10 #include <iostream> using namespace std; int main(){ int i; int sum = 0; for (i = 1; i <= 100; i++){ sum = sum+i; cout<<sum<<endl; } cout<<sum; return 0; }

Hmm. But in the case we delete a row (toghether with the ID) there will be a gap between the sequence of the ID's. Does auto_increment fill that gap when a new user is created, or will it just add 1 to the last id in the table?

x = 42; int num = 0; while (num <3) Consele.writeline (x); num++; int x = 42; is just an int with an asigned value of 42 int num=0; is what initiate the count for the while loop while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false consele.writeline (x) will display 42 while num < 3 num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false. so the consele.write will write 42 three times. x=42, remember the (x)

Using code playground, can someone tell me if the output for this code is normal or is something wrong with my code. It doesn't let me input velocity or time after I run it, is that normal for code playground? Total newbie to here. Just a simple code to calculate distance.

Hello Group,Is there any source where I could find multiple problem programming question on a single topic, so that I could get a good hang on those topics. for e.g, lets say I am learning 'if else' then I could have question and solve 30-40 examples on just 'if else'..Kind Regards,Adarsh

so far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.
