Overriding the what() Method

Medium Exception Handling in OOP

Solve in Playground →

Problem Statement

Extend `std::exception` by creating a `CustomException` class. Override the `virtual const char* what() const noexcept` method to return `”Custom Error Occurred”`. Read an integer. If it equals `404`, throw the exception. Catch it and print `e.what()`.

Input Format

A single integer.

Output Format

Print the custom overridden message or 'OK'.

Constraints

None

Sample Input

Sample Output

Custom Error Occurred

Explanation

Overriding `what()` allows you to provide a specific string description for your custom exception when it is caught generically.

Starter Code

#include <iostream>
#include <exception>

class CustomException : public std::exception {
public:
    // Override what() here
};

int main() {
    // Implement logic and catch
    return 0;
}
