c++ 产生错误后如何忽略错误继续执行？

Question

void goto_catch()
{

    int i =2;
    try {   
        i = i / 0;    
    }
    catch (...)
    {
        goto tiao;
    }
    tiao:
    cout << "ok" << endl;
}

我在手机上编译就能打印ok，vs上就中断了，所以这代码对吗？怎么设置才能让vs执行该命令呢？

Answer 1

#include<iostream>
#include<signal.h>
#include <setjmp.h>
using namespace std;

jmp_buf registers;

void handler(int)
{
    longjmp(registers,1);
}

int main(void){
    signal(SIGFPE,handler);
    
    int i = 2 , b = 0;

    if(1 == setjmp(registers))
    {
        goto tiao;
    }

    i = i / b;

tiao:
    cout << "ok" << endl;

}
