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

it is a usefull advice in learning this html course , leave html5 at the bigining & learn java script completly because in some sections (from 10/19 to end of the course) you need basic & even advance knowledge of JS . then your able to return to previous course & learn html5 easier.
goodluck.
