Try to figure out how to use while but something went WRONG

I use cppDroid #include <iostream> using namespace std; int num = 0; while (num < 20) { cout << "Number: " << num << endl; num++; } The output is /buildSources/while.cpp:5:1: error:expected unqualified_id before 'while' while (num < 20){ ^ Return code is not 0 Can someone help me?

// So it's true that we need to do everything here huh. #include <iostream> using namespace std; int main() { int num = 0; while (num < 20) { cout << "Number: " << num++ << endl; } }

Your main function is missing.

silencer 45 Or you might consider a reverse solution besides your original approach as //... int main() { int num = 20; while (num--) cout << num << endl; } Output : 19 18 . . . 1 0

I guess that's because you forgot int main()
