Catching All Exceptions in C++
To catch all kinds of exceptions in our catch block in C++, we can define the catch block using the catch-all clause – catch (…),
Syntax
try { // code that can raise an exception throw ExceptionType("Error message"); } catch(...){ // catch all type of unknown exceptions }
C++ Program to Catch All Exceptions
In the following example we have used the catch(…) block to catch all kind of unknown exceptions that might occur during the execution of the program.
// C++ program to illustrate how to catch all exceptions
#include <iostream>
#include <stdexcept>
using namespace std;
int main()
{
try {
// Code that can throw exceptions
int x = 10;
int y = 0;
if (y == 0)
throw runtime_error("Divide by zero exception");
int result = x / y;
}
// catch the excepetion
catch (const runtime_error& e) {
// Handle divide by zero exception
cout << "Exception: " << e.what() << endl;
}
// Handle all other types of exceptions
catch (...) {
cout << "An unknown exception occurred" << endl;
}
return 0;
}
Output
Exception: Divide by zero exception
Time Complexity: O(1)
Auxiliary Space: O(1)
How to Catch All Exceptions in C++?
In C++, exceptions are objects that indicate you have an error in your program. They are handled by the try-catch block in C++. In this article, we will learn how to catch all the exceptions in C++.
