Question

Here is a function that takes, and returns pointers:

2

int* select(bool which, int* a, int* b) {
    if(which == true)
        return a;
    else
        return b;
}

Using this function, suppose we have variables x, y:

int x = ..., y = ...;

int* p = select(x < y, &x, &y);
if(p == &x)
    cout << "Yes";
else
    cout << "No";

• What will this print if x = 5, y = 7?

• What will this print if x = 23, y = 9?

Answer 1

What will this print if x = 5, y = 7?

OUTPUT: Yes

What will this print if x = 23, y = 9?

OUTPUT: No
