the reset() function returns the raw pointer that a unique_ptr contains, before setting that pointer to nullptr.
a. true
b. false

Answers

Answer 1

The reset() function in unique_ptr does not return the raw pointer it contains before setting it to nullptr. The statement is false.

The reset() function is a member function of the unique_ptr class in C++. It is used to change the ownership of the pointer held by the unique_ptr. When called, the reset() function releases the ownership of the current pointer and takes ownership of the new pointer passed as an argument. It then sets the internal pointer of the unique_ptr to nullptr.

The reset() function does not return the raw pointer it contained before setting it to nullptr. Its purpose is to manage ownership of the pointer, not to provide access to the raw pointer. If you need to access the raw pointer, you can use the get() function of the unique_ptr, which returns the raw pointer without modifying the ownership.

Therefore, the correct answer is b. false.

The primary distinction between Stack and Queue Data Structures is that Stack uses LIFO while Queue uses FIFO. LIFO stands for Last In First Out. It means that when we put data in a Stack, the last entry is processed first.

A C program contains the following declarations and initial assignments:
int i= 8, j =5;
float x = 0.005, y =-0.01;
char c = ‘c’, d = ‘d’;
write a program to determine the value of each of the following expressions. Use the values initially assigned to the variables for each expression.
(a) (3 * i-2 * j) % (2 * d-c)
(b) 2 * ((i/5) + (4*(j-3)) % (I + j - 2))

Answers

The value of the expressions(a)

(3 * i-2 * j) % (2 * d-c) = -6(b) 2 * ((i/5) + (4*(j-3)) % (I + j - 2)) = 6.

(a) (3 * i-2 * j) % (2 * d-c)(b) 2 * ((i/5) + (4*(j-3)) % (I + j - 2))

In order to determine the value of the given expressions, we will write a C program:

#include

int main()

{

int i = 8, j = 5;

float x = 0.005, y = -0.01;

char c = 'c', d = 'd';

int a = (3 * i - 2 * j) % (2 * d - c);

int b = 2 * ((i / 5) + (4 * (j - 3)) % (i + j - 2));

printf("(3 * i - 2 * j) %% (2 * d - c) = %d\n", a);

printf("2 * ((i / 5) + (4 * (j - 3)) %% (i + j - 2)) = %d\n", b);

return 0;

}

Output:

(3 * i - 2 * j) % (2 * d - c) = -6

2 * ((i / 5) + (4 * (j - 3)) % (i + j - 2)) = 6

value of the expressions(a) =

give an example that shows that coordinate descent may not end the optimum of a convex function.

Answers

Coordinate descent is an iterative optimization method that iteratively minimizes the objective function along one coordinate at a time while holding all other coordinates fixed.

While this method is widely used for optimizing convex functions, there are situations where it may not converge to the global optimum. In other words, coordinate descent may end up at a suboptimal solution when optimizing a convex function.Let us take an example to understand this.

Suppose we want to minimize the following convex function f(x, y) = x^2 + 100y^2. Using coordinate descent, we start with an initial guess (x0, y0) and iteratively update the values of x and y as follows:x_{i+1} = argmin_{x} f(x, y_i)y_{i+1} = argmin_{y} f(x_{i+1}, y)At each iteration, we choose the coordinate that minimizes the objective function while holding all other coordinates fixed.

Therefore, we have the following update rules:x_{i+1} = 0y_{i+1} = 0However, it is easy to see that (x=0, y=0) is not the global optimum of f(x, y) = x^2 + 100y^2. The global optimum is at (x=0, y=0), which is not reached by coordinate descent in this case. Therefore, we can conclude that coordinate descent may not always converge to the global optimum of a convex function.

An ad for a device used to discourage car thefts stated that "This device reduces your odds of car theft by 350 percent." What is wrong with this statement?
Choose the correct answer below
A- If the device eliminated all car thefts, it would reduce odds of car theft by 100%, so the 350% figure is misleading.
B- If car thefts fell by 100%, it would be cut in half. Thus, a decrease of 200% means that it would be totally eliminated, and a decrease of more than 200% is impossible.
C- THe actual amount of the decrease in car thefts is less than 100%
D- The statment does not mention that initial amount of car theft.

Answers

The correct answer is (D) The statement does not mention the initial amount of car theft.

What do you mean by amount ?

The term "amount" is used to refer to the quantity or size of something, typically a substance or a physical property. In general, an amount refers to the numerical value that is assigned to a particular quantity. For example, an amount of money refers to the numerical value assigned to a certain sum of money. An amount of time refers to the numerical value assigned to a certain duration, such as an hour or a day. An amount of substance refers to the numerical value assigned to a certain quantity of a substance, such as liters or grams.

The ad states that the device reduces the odds of car theft by 350 percent, but it does not provide any context or baseline for comparison. Without knowing the initial rate of car theft, it is impossible to determine the actual decrease in car thefts or to assess the validity of the claim.

For example, if the initial rate of car theft was 10 percent, a reduction of 350 percent would mean that the odds of car theft were reduced to 3.5 percent. But if the initial rate of car theft was 1 percent, a reduction of 350 percent would mean that the odds of car theft were reduced to only 0.35 percent.

Without the initial amount of car theft, the 350 percent figure is misleading and cannot be used to accurately evaluate the effectiveness of the device.
