如何在本地cpp中捕获异常? [英] how to catch exceptions in native cpp?

问题描述

伙计们
我对本机cpp相对熟悉，但从未使用过异常处理.
现在，我需要帮助来了解如何捕获这样的异常

Helo guys
I am relatively familiar with native cpp but never used exception handling.
Now I want help to understand how can I catch exceptions like this

try
{
    int p = 0;
    int q = 0;
    int r = p / q;//divide by zero exception
}
catch (???)//what should I write here instead of ????
{
    .....
}

try
{
    int * p = 0;
    * p = 0;
}
catch (???)//what should I write here instead of ????
{
}

由abzadeh先生附加:我发现通过try {} catch {}机制无法解决被零除和访问冲突异常的问题.我认为catch块可以捕获程序员显式抛出的执行.
现在我的问题是:

Any suggestion about how to find usefull articles is appreciated
Thanks in advanmce

appended by mr.abzadeh:I have found that divide by zero and access violation exceptions are not handled thru try {} catch {} mecanism. I think the catch block catches exections explicitly thrown by programmer.
Now my question is:
Is there any mechanism to catch exceptions like integer divide by zero and access violation in native c++?

推荐答案

异常处理如下:

Exception handling is as follows:

try
{
 // risky code
}
catch(Excetpion_Name& ex)
{
 // handle here
}

您可以使用以下类型捕获所有异常，无论其类型如何:

You can catch all exceptions regardless their type with:

catch(...)
{

}
