Shouldnt this ask for a second imput if the number is negative

#include <iostream> using namespace std; int factorial(int n) { if (n<=1) { return 1; } else { return n * factorial(n-1); } } int main() { int x; cin >> x; while(x<=-1){ cout << "try again"; cin >> x;} cout << factorial(x); }

If you're running it on codeplayground, you can only get one input at start of run-time. Just the way code playground is designed.

AIDE-IDE might be ok for mobile. Never actually tried it, just an assumption on number of downloads.
