Really basic implementation of Fibonacci's formula in C++, please don't blame me if something is written badly. I'm not a GREAT programmer tho.

fibonacci.cpp

// Basic implementation of Fibonacci's sequence in C++.

#include <iostream>

int main(int argc, char * argv[]) {
    unsigned int x, y, z, n;
    std::cout << "Number of iterations: ";
    std::cin >> n;
    
    for (unsigned int i = 0; i < n; i++) {
        z = x + y, x = y, y = z;
        std::cout << z << '\n';
    }
    
    return 0;
}
