如何捕获整数除以零并在本机C++中访问违规异常

#include<iostream>
#include <stdexcept>

int main() {
    int a = 10;
    int b = 0;

    try {
        if (b == 0) {
            throw std::runtime_error("除数不能为零");
        }
        int result = a / b;
        std::cout << "结果为："<< result<< std::endl;
    } catch (const std::runtime_error& e) {
        std::cerr << "捕获到异常：" << e.what()<< std::endl;
    }

    return 0;
}

#include<iostream>
#include <csignal>
#include <cstdlib>

void signalHandler(int sig) {
    std::cerr << "捕获到信号："<< sig<< std::endl;
    exit(1);
}

int main() {
    signal(SIGFPE, signalHandler);

    int a = 10;
    int b = 0;

    int result = a / b;
    std::cout << "结果为："<< result<< std::endl;

    return 0;
}
