Fibonacci Sequence

Hello team,

I need to create in C++ code that will count proper fibonacci number for user input. I have tried couple hours without a succes. Below you can find my code. For example input 12 > output 144.

Can someone help me:

#include <iostream>

using namespace std;
long double fib[10000];
int n;
int i;
int main()
{
    cin >> n;
    fib[0] = 1;
    fib[1] = 1;
    for (i=2; i<n; i++) {
        fib[i]= fib[i-1] + fib[i-2];
    }
    for (i=0; i<n; i++) {
        cout<<endl<< fib[i];
    }
    return 0;
}```

Since 144 is the correct final term for a sequence of length 12, perhaps you're just not seeing the rest of the output. Try putting the line end after the value:

        cout << fib[i] << endl;

Also, since C# is the closest language here to C++, perhaps any future questions would be better posted in that topic area.
