Write a c++ program that evaluates the first 50 numbers of the Fibonacci sequence and store the numbers in an array.

The c++ program asks the user for an input to enter a positive integer 'n' and display the nth fibonacci number "FibN" that is stored inside of the array

Answer #1
#include <iostream>

using namespace std;

int main() {
    unsigned long long int FibN[50];
    FibN[0] = 0;
    FibN[1] = 1;
    for (int i = 2; i < 50; ++i) {
        FibN[i] = FibN[i-1] + FibN[i-2];
    }
    cout << "First 50 fibonacci numbers are" << endl;
    for (int i = 0; i < 50; ++i) {
        cout << FibN[i] << endl;
    }

    cout << "Enter a positive integer: ";
    int n;
    cin >> n;
    cout << "Fibonacci of " << n << " is " << FibN[n-1] << endl;
    return 0;
}

ARM Assembly Code The Fibonacci Sequence is a series of integers. The first two numbers in the sequence are both 1; after that, each number is the sum of the preceding two numbers. 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... For example, 1+1=2, 1+2=3, 2+3=5, 3+5=8, etc. The nth Fibonacci number is the nth number in this sequence, so for example fibonacci(1)=1, fibonacci(2)=1, fibonacci(3)=2, fibonacci(4)=3, etc. Do not use zero-based counting; fibonacci(4)is 3, not...
