Multi-Case-Logik mit Fallthrough

#include <iostream>
 
void processCommand(int cmd) {
    switch (cmd) {
        case 1:
        case 2:
            std::cout << "Handling basic command..." << std::endl;
            [[fallthrough]]; // Explicitly indicating intentional fallthrough
        case 3:
            std::cout << "Performing advanced processing..." << std::endl;
            break;
        default:
            std::cout << "Unknown command." << std::endl;
    }
