What is a DDoS attack and how can C++ be used to implement a basic simulator?

A Distributed Denial-of-Service (DDoS) attack aims to overwhelm a target system with traffic from multiple compromised sources, making it unavailable to legitimate users. In C++, one could simulate this by creating multiple threads, each acting as a 'bot'. These threads would concurrently send requests (e.g., UDP packets or HTTP requests) to a target IP address and port, mimicking the distributed nature of a real DDoS attack. The core idea is to saturate the target's network bandwidth or processing capacity.
