当整数被零除时，msvc 6 会抛出什么异常？
我做了一些实验，发现当整数除以零时会引发异常。
#include <iostream>
#include <stdexcept>
using namespace std;
int main
(
void
)
{
try
{
int x = 3;
int y = 0;
int z = x / y;
cout << "Didn't throw or signal" << endl;
}
catch (std::exception &e)
{
cout << "Caught exception " << e.what() << endl;
}
return 0;
}
显然它没有抛出 std::exception。它还可能扔什么？
I have been doing a bit of experimenting, and have discovered that an exception is being thrown, when an integer divide by zero occurs.
#include <iostream>
#include <stdexcept>
using namespace std;
int main
(
void
)
{
try
{
int x = 3;
int y = 0;
int z = x / y;
cout << "Didn't throw or signal" << endl;
}
catch (std::exception &e)
{
cout << "Caught exception " << e.what() << endl;
}
return 0;
}
Clearly it is not throwing a std::exception. What else might it be throwing?

这是一个 Windows 结构化异常，与 C++ 无关 - 如果它是 C 程序，您会得到相同的异常。
It's a Windows structured exception, which has nothing to do with C++ - you would get the same exception if it were a C program.
本文声称有一种方法可以使用 _set_se_translator 功能。

This article claims to have a way to convert a structured exception to a C++ exception using the _set_se_translator function.

结果未定义，您可以使用 __try / __ except 块捕获错误（结构化异常处理）。但是，为什么不在除法之前简单地检查错误呢？
The result is undefined, you could use __try / __except block to catch the error (structured exception handling). However, why not simply check for the error before your division?
在 msvc6 中，您可以使用 catch(...) 捕获它并使用 throw 重新抛出它；但是，由于您无法以这种方式检测异常类型，因此您最好做其他事情。
In msvc6 you can catch it with catch(...) and rethrow it with throw; however since you can't detect exception type that way you're better off doing something else.
