Discussions Q&R
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

what have i to do, if i want that the program always writes for example :
0+1
1+2
3+3
6+4
10+5
15+6
...
because now it just writes

3

10
15
...
and maybe if it works, can i make then
0+1=1
1+2=3
3+3=6
6+4=10

Matt reaches the final round of a treasure hunt. In this, he finds that as he proceeds there are flags with the number written on them at different positions. The difference between two consecutive flags can be either a or b. If he finds the number on the first flag is 0. Given three integer, first one is number of flags present, second is a and third is b. then return all the possible values for last flag for each test case.
hunt({3 1 2}) = {2 3 4}
