int main()

{ int i = 3, j = 4; int x = 0;

try

{ if(i < j) throw “Oops!”; }

catch(int i)

{ x = 1; }

catch(double d)

{ x = 3; }

catch(...)

{ x = 4; }

cout << "x = " << x << endl; return 0; }

Answer 1

x = 4




int main() {
    int i = 3, j = 4;
    int x = 0;

    try {
        if (i < j)  // i < j is true, so, below throw statement is executed. throw throws a string.
            throw "Oops!";
    }
    catch (int i) { x = 1; }    // this is not executed because throw didn't throw an int
    catch (double d) { x = 3; } // this is not executed because throw didn't throw an double
    catch (...) { x = 4; }  // this is executed because none of the above throws were executed. this set's x to 4

    cout << "x = " << x << endl;    // this prints 4
    return 0;
}
