By referring to C++ catching all exceptions
try {
int i = 0;
int j = 0/i; /* Division by 0 */
int *k = 0;
std::cout << *k << std::endl; /* De-reference invalid memory location. */
}
catch (...) {
std::cout << "Opps!" << std::endl;
}
The above run-time error are unable to be detected. Or, am I having wrong expectation on C++ exception handling feature?
If you dereference a pointer that doesn’t point to an object, you don’t get an exception, you get undefined behavior. Anything can happen.
Usually, if you dereference a null pointer, as you do in your example, the program will crash.
