Question

C++ :

Write a program that demonstrates several exception types being caught with the catch(...) exception handler.

Answer 1

#include <iostream>
using namespace std;

int main() {
    try {
        throw 123;
    } catch(int n) {
        cout << "caught int " << n << endl;
    } catch(double n) {
        cout << "caught double " << n << endl;
    } catch(char *s) {
        cout << "caught string " << s << endl;
    } catch (...) {
        cout << "caught something unknown" << endl;
    }

    try {
        throw 123.45;
    } catch(int n) {
        cout << "caught int " << n << endl;
    } catch(double n) {
        cout << "caught double " << n << endl;
    } catch(char *s) {
        cout << "caught string " << s << endl;
    } catch (...) {
        cout << "caught something unknown" << endl;
    }

    try {
        throw "hello";
    } catch(int n) {
        cout << "caught int " << n << endl;
    } catch(double n) {
        cout << "caught double " << n << endl;
    } catch(char *s) {
        cout << "caught string " << s << endl;
    } catch (...) {
        cout << "caught something unknown" << endl;
    }

    return 0;
