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

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.

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?
