What’s the purpose of the scope resolution operator?

(a) If ||A|| is an operator norm, prove that

$$\| I \| = 1,$$

where I is an identity matrix. (b) Is there a vector norm that induces the Frobenius norm as an operator norm? Why or why not?

In the diagram shown in Figure 14-20, what do we call the Assignment class?

Control:

if my_var % 2:
    if my_var**3 != 27:
        my_var = my_var + 4
    else:
        my_var /= 1.5 
else:
    if my_var <= 10:
        my_var *= 2
    else:
        my_var -= 2 
print(my_var)

(a) Find four values of my_var so each of the four assignment statements will be executed: each value should cause one assignment statement to be executed.

(b) Find four ranges of my_var values that will cause each of the four assignment statements to be executed.

What is the purpose of the delete operator?

Briefly describe how the | | operator works.

What is the instanceof operator of a class?

A tour operator has three vans, and each can accommodate seven tourists. Suppose 14 people arrive for a city sightseeing tour and the operator will use only two vans. In how many ways can the operator assign the people to the vans?

Briefly describe how the || operator works.

Given:

int num1, num2, newNum;
double x, y;

Is the assignment x / y = x * y; valid? If it is not valid, state the reason.

Show that the operator $\hat{p}^{\prime}$ obtained by applying a translation to the operator $\hat{p}$ is $\hat{p}^{\prime}=\hat{T}^{\dagger} \hat{p} \hat{T}=\hat{p}$.

What does the operator delete do?
