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

I need to design a recursive function called replicate recur which will receive two arguments: times which is the number of times to repeat and data which is the number or string to be repeated.
The function should return an array containing repetitions of the data argument.
For instance, replicate_recur (3, 5) should return [5,5,5].
If the times argument is negative or zero, return an empty array. If the argument is invalid, raise ValueError.
