What is the output of this program?

    using namespace std;
    int main()
    {
        try
        {
            throw 13;
        }
        catch (int ex)
        {
            cout << "Exception number: " << ex << endl;
            return 0;
        }
        cout << "No any Exception..." << endl;
        return 0;
    }

Correct Option: A

If we caught a integer value means, there will be an exception, if it is not a integer, there will not be a exception.

What is the output of this program?

#include <iostream>
    #include <exception>
    using namespace std;
    struct NewException : public exception
    {
        const char * what () const throw ()
        {
            return "Interview Mania";
        }
    };
    int main()
    {
        try
        {
            throw NewException();
        }
        catch(NewException& e)
        {
            cout << "Exception Caught..." << std::endl;
            cout << e.what() << std::endl;
        }
        catch(std::exception& e)
        {
        }    
    }

Correct Option: E

We are defining the user-defined exception in this program.

What is the output of this program?

#include <iostream>
    using namespace std;
    int main()
    {
        double num1 = 9, num2 = 3, Result;
        char Operator = '/';
        try 
        {
            if (num2 == 0)
                throw "Division by zero not allowed";
            Result = num1 / num2;
            cout << num1 << " / " << num2 << " = " << Result;
        }
        catch(const char* S)
        {
            cout << "\n Bad Operator: " << S;
        }
        return 0;
    }

Correct Option: C

In this program, We are dividing the two variables and printing the result. If any one of the operator is zero means, it will arise a exception.
