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

can someone kindly correct me if i am wrong about this quote "As the program contains multiple lines of code, you should create it as a separate file and run it."
does that mean that if my code gets bigger it is advisable to create less line of codes but many files?
