Question

Consider the following C code: double balance; try { cout << "Enter the balance: "; cin >> balance; cout << endl; if (balance < 1000.00) throw balance; cout << "Leaving the try block." << endl; } catch (double x) { cout << "Current balance: " << x << endl << "Balance must be greater than 1000.00" << endl; } In this code, identify the try block. In this code, identify the catch block. In this code, identify the catch block parameter and its type. In this code, identify the throw statement.

Answer 1

Answer:

Answer given below

Explanation:

Program:

1. double balance;

2. try{

3. cout<<"Enter the balance :";

4. cin >> balance;

5. cout<<endl;

6. if(balance < 1000.00)

7. throw balance;

8. cout<<"Leaving the try block."<<endl;

9. }

10. catch(double x){

11. cout<<" Current balance : "<<x<<endl<<"Balance must be greater than 1000.00"<<endl;;

12. }

Answer A:

If we consider the above program lines, try block represents from 2 to 9 lines.

Answer B:

If we consider the above program lines, catch block represents from 10 to 12 lines.

Answer C:

catch block parameter is x and its type is double.

Answer D:

If we consider the above program lines, line number 7 indicates throw statement.
