=== 多catch块示例 ===
<syntaxhighlight lang="cpp">
#include <iostream>
#include <stdexcept>

void processInput(int value) {
    try {
        if (value < 0) throw std::out_of_range("值太小");
        if (value > 100) throw std::out_of_range("值太大");
        if (value == 42) throw std::logic_error("禁止的值");
        
        std::cout << "处理值: " << value << std::endl;
    }
    catch (const std::out_of_range& e) {
        std::cerr << "范围错误: " << e.what() << std::endl;
    }

        std::cerr << "逻辑错误: " << e.what() << std::endl;
    }
    catch (...) {  // 捕获所有其他异常
        std::cerr << "未知错误发生" << std::endl;
