Even more modern, we are getting C++26 nowadays.

CTADs for vector (no need for explicit string), ranges enumeration, and range-based for-loop with structured types

    int main() {
        vector vec = { 
            "the", "quick", "brown", "fox", 
            "jumped", "over", "the", "lazy", "dog" 
        };

        for (auto&& [i, it] : vec | std::views::enumerate)
            println ("{}:{}", ++i, it);
    }
