how to handle the exception handling when NEW operator failed to allocate memory

[jayapal]

Hi ,

I am using the NEW operator to allocate the memory in many places of
my code.But I am not doing any error hadling or exception handling.Can
any one suggests me how to do exception handling, which code part I
have to add to do the exception handling

Thanks in advance,

I believe you mean the "new operator" (C++ is case sensitive).

What book on C++ are you reading that doesn't give any "suggestions"?

Error handling and exceptions are not the same thing nor they have the
same purpose. Books have been written to try to explain those concepts
and not many actually succeed, unfortunately. Start with chapter 14
in TC++PL. Then ask more question if you get any.

Hi,

I worked too hard to find the solution and found that this is a
standard exception which is thrown by new itself.

// bad_alloc standard exception
#include <iostream>
#include <exception>
using namespace std;

int main () {
try
{
int* myarray= new int[1000];
}
catch (exception& e)
{
cout << "Standard exception: " << e.what() << endl;
}
return 0;
}
