I really need help please this problem is very confusing for me it is in C++

The Fibonacci sequence:
unsigned fibonacci (unsigned n, unsigned& recursions);
void fibonacci(unsigned f[], unsigned n);
The first function is to solve the problem recursively and return the Fibonacci value of n as the
result. In addition, it shall store the number of recursive calls in the recursions parameter.
For example, assume recursions is an unsigned int variable in main() and is set to 0 before
each of call to the fibonacci function.
Calling fibonacci (0, recursions) should return 1 and store 0 in recursions since
there is no need for recursive call.
●
Calling fibonacci (2, recursions) should return 2 and store 2 in recursions since
this call would have trigger two recursive calls: fibonacci (0, recursions) and
fibonacci (1, recursions).
Calling fibonacci (3, recursions) should return 3 and store 4 in recursions since
this call would first trigger fibonacci (2, recursions) and fibonacci (1,
recursions). In addition, fibonacci (2, recursions) would trigger fibonacci (1,
recursions) and fibonacci (0, recursions).
The second function is to create the first n values of the Fibonacci sequence and store them in
the array parameter using an iterative approach. Do not use any nested loop. For example,
assume results is an array of unsigned int.
Calling fibonacci (results, 5) should store {1, 1, 2, 3, 5} in the first five elements of
results.
Calling fibonacci (results, 10) should store {1, 1, 2, 3, 5, 8, 13, 21, 34, 55} in the first
ten elements of results.
