    new operator returns null value if memory allocation is unsuccessful. The new operator will throw a std::bad_alloc exception on failure and this can be handled by exception handling as follows.
    try
    {
    char* cPtr = new char[50];
    }
    catch (std::bad_alloc&)
    {
    // Handle error
    }
