Nested loops

Read first Task 15

An inner loop runs completely for every outer step.

Task

How many lines does the nested loop print?

The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.

What you start with

#include <iostream>
using namespace std;

int main() {
    for (int row = 1; row <= 2; row++) {
        for (int col = 1; col <= 3; col++) {
            cout << row << "-" << col << " ";
        }
        cout << endl;
    }
    return 0;
}
