can someone please explain to me how moving objects are produced ? (example in games). must I use graphics.h?. how do I transform it from simply a compiled piece of code in code block to a real software?. I've been googling this for days now and I'm still confused. Please an extensive explanation would be appreciated🙏. Thanks. p. s you can also recommend websites where I can learn more and see good sample codes.

hey guys, I've been trying to work out the formula 'v=I*r'. But whenever I run the program and input values for I and r, it doesn't give the right answer. This is the code #include <iostream> using namespace std; int main() { int i,r; int v = i*r; cout<<"what is the value of i?\n"; cin>>i; cout<<"what is the value of r?\n"; cin>>r; cout<<"voltage ="<<v<<endl; return 0; } p/s: I'm new to programming

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!

How exactly do I access the files I saved in the code playground? Do you have to make them public in order for them to save? Since I've been trying to save things, but I can't find where they show up. Thanks.

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.
