Opinion 1:

Consider the following code snippet:

int n;
float f;  
cout << "Enter an integer and a float: ";
cin >> n >> f;
cout << "The integer is: " << n << endl;
cout << "The float is: " << f << endl;

If the user types 3.7 at the prompt, the program will output:

1. The integer is: 3.7
   The float is: 0
2. The integer is: 3
   The float is: <garbage>
3. The integer is: 4
   The float is: <garbage>
4. The program will print something else.
5. The program will crash.

Question 2:

Consider the following code snippet

float x = 7;
float y = 11;
Point p(3,2);
p.setX(y);
p.print();
  

What is the output of this program?

1. (3, 11)
2. (7, 11)
3. (11, 2)
4. (3, 2)
5. This will generate an error

Question 3:

Consider the following code snippet

Point p;
Point *ppt, *qpt;
ppt = &p;
qpt = ppt;
qpt->setX(10);
p.print();
  

What is the output of this program?

1. (0, 0)
2. (10, 0)
3. The program will not compile.
4. The program will generate an error when run.
