# Collatz conjecture
Suggested code solution.
```cpp
#include
using namespace std;
int main() {
int N;
cout << "Please enter an integer > 1: ";
cin >> N;
while(N != 1){
cout << N << ' ';
if (N % 2 == 0) {
N = N / 2;
}
else {
N = 3 * N + 1;
}
}
cout << endl << "And we have finally reached " << N;
return 0;
}
```
