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

Is it possible to make my code run without having to press Enter on my IDE? For example: if I'm making a calculator and I want the calculations to be made as soon as I press "=" after typing the numbers and the operator?
Say I wanted to add two numbers: can it calculate automatically as soon as I write "2+3=" without having to press Enter?

In the short code below, I declared an array of five elements. But I'm getting confused on how to use it in a while loop. My main question is , if the user inputs a userchoice1 value that is less than 1, I want the code to keep looping until the user inputs a number that is not less than 1. But I don't know if the 7th line (userchoice1 [x]++) shows the right way to loop it.

2 Answersso 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.
