Source code for multilevel queue program in c plus plus?

Here’s a simple implementation of a multilevel queue scheduling program in C++. In this program, processes are categorized into three different queues based on their priority.

<code class="language-cpp">#include <iOStream>
#include <queue> #include <string>
struct Process { int id; int priority; // Lower number indicates higher priority };
int main() { std::queue<Process> high, medium, low; // Example: Adding processes to queues high.push({1, 1}); medium.push({2, 2}); low.push({3, 3});
// Scheduling processes based on priority while (!high.empty() || !medium.empty() || !low.empty()) { if (!high.empty()) { std::cout << "Processing high priority: " << high.front().id << std::endl; high.pop(); } else if (!medium.empty()) { std::cout << "Processing medium priority: " << medium.front().id << std::endl; medium.pop(); } else if (!low.empty()) { std::cout << "Processing low priority: " << low.front().id << std::endl; low.pop(); } } return 0; }

You can expand this program by adding more features such as user input for processes, time quantums, or different scheduling algorithms.
