Literally, I have been asked this question ""The Fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, … ; the first two terms are 0 and 1, and each term thereafter is the sum of the two preceding terms – i.e., Fib[n] = Fib[n – 1] + Fib[n – 2]. Using this information, write a C++ program that calculates the nth number in a Fibonacci sequence, where the user enters n in the program interactively. For example, if n = 6, the program should display the value 8."

I have code that works for giving me an answer;

```
#include <stdio.h>
#include <iostream>
using namespace std;
int main () {
int N;
unsigned long long Fib(int N);
cout<<"Enter your value: ";
cin>>N;
if (N<1) {
cout<<"Please chose another value";
cin>>N;
} else {
{
unsigned long long u = 0, v = 1, t;
for(int i=2; i<=N; i++)
{
t = u + v;
u = v;
v = t;
cout<<t<<"is your answer";
}
return v;
}
}
```

However, I am looking to find a way to display only one term...When it gives the answers it displays the entire sequence, when really I want only the Nth value (as in the question above). Any help on how to do it would be great. Thanks :)
