I suppose something would be causing the system to crash, so you should be checking for errors, and handling them.

For example, you could try using assert, but thats becoming replaced with the more popular exceptions, for example:

(Toggle Plain Text)

class Exception : public std::exception
{
    ...
};

class DivByZeroException : public Exception
{
    ...
};

(Toggle Plain Text)

...
if(IsZero(val))
    throw DivByZeroExc();
...

and in main, for example, you could have:

(Toggle Plain Text)

int main()
{
    try
    {
        ... //do something
    }
    catch(Exception x)
    {
        //handle
    }
}

Google for exceptions. That should help.

I'm not. I honestly couldn't figure out what he was trying to say, other than his program crashed (or keeps crashing), and he wants to know what to do. He phrases it like a multiple choice ("which is better way"), but doesn't indicate which options are available, or which have been considered. There was no helpful information given, no specific details of what he was trying to accomplish or how the program was crashing.

In that, the post was no different than many others we get here, but the abuses he heaped upon the English language cried out for response. Yes, I realize that English is most certainly not the native language of the OP, but that post was just incomprehensible.

I was kidding!

Suppose you have a [???] product system which is built in Linux. Now due to an unknown reason, the system crashes because of the software. How do you handle the crash, and what is the best way?

Something like this should be implemented in forum registration

Debug the product and reboot the system.

Invest in a wetware upgrade for the biological component of the system. This should remedy a lot of the inter-system communications issues.

I would handle it by displaying a message blaming the end user for breaking my code
