  1. 1#include <iostream>
    using namespace std;
    int main()
    {
    int x = -1;
    try {
    cout << "Inside try n";
    if (x < 0)
    {
    throw x;
    cout << "After throw n";
    }
    }
    catch (int x ) {
    cout << "Exception Caught n";
    }

    cout << "After catch n";
    return 0;
    }
    1. AInside try
      Exception Caught
      After throw
      After catch
    2. BInside try
      Exception Caught
      After catch
    3. CInside try
      Exception Caught
    4. DInside try
      After throw

  2. 2What is the advantage of exception handling ?
    1.Remove error-handling code from the software's main line of code.
    2. A method writer can chose to handle certain exceptions and delegate others to the caller.
    3. An exception that occurs in a function can be handled anywhere in the function call stack.
    1. Aonly 1
    2. B1, 2, 3
    3. C1,3
    4. D1,2
  3. 3What should be put in a try block?

    1. Statements that might cause exceptions
    2. Statements that should be skipped in case of an exception
    1. AOnly 1
    2. BOnly 2
    3. CBoth 1 and 2
  4. 4Output of following program
    #include<iostream>
    using namespace std;

    class Base {};
    class Derived: public Base {};
    int main()
    {
    Derived d;
    try {
    throw d;
    }
    catch(Base b) {
    cout<<"Caught Base Exception";
    }
    catch(Derived d) {
    cout<<"Caught Derived Exception";
    }
    return 0;
    }
    1. ACaught Derived Exception
    2. BCaught Base Exception
    3. CCompiler Error

    throw 'a';
    }

    {
    cout << "int exceptionn";
    }
    catch (...)
    {
    cout << "default exceptionn";
    }
    cout << "After Exception";
    return 0;
    }
    1. Adefault exception
      After Exception
    2. Bint exception
      After Exception
    3. Cint exception
    4. Ddefault exception
  6. 6#include <iostream>
    using namespace std;

    int main()
    {

    }

    return 0;
    }
    1. Adefault exception
    2. Bint exception
    3. CCompiler Error

    }
    catch (int x)
    {
    cout << "Outer Catchn";
    }
    return 0;
    }
    1. AOuter Catch
    2. BInner Catch
    3. CInner Catch
      Outer Catch
    4. DCompiler Error
  8. 8#include <iostream>

    cout << "Caught " << i << endl;
    }
    }#include <iostream>

    }
    ~Test() { cout << "Destructing object number " << id << endl; }
    };

    int Test::count = 0;

    int main() {
    try {

  10. 10Which of the following is true about exception handling in C++? 1) There is a standard exception class like Exception class in Java. 2) All exceptions are unchecked in C++, i.e., compiler doesn't check if the exceptions are caught or not. 3) In C++, a function can specify the list of exceptions that it can throw using comma separated list like following.
    void fun(int a, char b) throw (Exception1, Exception2, ..)
    1. A1,3
    2. B1,2,3
    3. C1,2
    4. D2,3
