Question

What is the std::exception class in C++?

Answer 1

std::exception is a standard C++ class defined in the <exception> header. It serves as a base class for all exceptions. It provides a what() member function that returns a descriptive string about the exception.

Example code:

#include <iostream>
#include <exception>

int main() {
    try {
        throw std::runtime_error("Something went wrong!");
    }
    catch (const std::exception& e) {
        std::cout << "Exception caught: " << e.what() << std::endl;
    }

    return 0;
}
