How to loop through an array and print its elements in C++?

Question

I have a problem...
How to make this code work?
#include <iostream>
using namespace std;
int main() {
int arr[3] = {0,1,0};
.......}

And then what to write after that?

//Thanks

Answer 1

int arr[3] = {0,1,0};
for(int i = 0; i < 3; i++)
{
cout << arr[i];
}

You're kidding about this or what :)

Answer 2

Ipang, do you also know how to loop through 2d arrays?

Answer 3

@Reuben I'm learning about that too, here's what I did just minutes ago, there's a weird thing though, there's a line that doesn't get executed in the end before return, idk why or what. Maybe you can check if that line works??
