Which type of styles can be applied to a word, phrase, or sentence?

Which of the following code is correct? I: print("Programming is fun") print("Python") print("Computer Science") II: print("Prog

vfiekz [6]

Answer:

None of the options is correct.

Explanation:

One of the simplest statements that you can write in Python is a print statement, which causes a message to be displayed on the screen. For example, the following statement causes the message Python programming is fun! to be displayed:

print 'Python programming is fun!'

Notice that after the word print, the Python programming is fun! was written inside a set of single-quote marks. The quote marks are necessary, but they will not be displayed. They simply mark the beginning and the end of the text that we wish to display.

Here is an example of how you would type this print statement at the interpreter’s

prompt:

>>> print 'Python programming is fun!'

After typing the statement you press the Enter key and the Python interpreter executes the statement, as shown here:

>>> print 'Python programming is fun!'

Python programming is fun!

>>>

Thus, the correct way to write the codes in the question is:

print 'Programming is fun'

print 'Python'

print 'Computer Science'

Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off. The follow

Dafna11 [192]

Answer:

1)

officeAC = new AirConditioner();

officeAC.turnOn();

2)

officeAC = new AirConditioner();

officeAC.turnOn();

officeAC.setTemp(69);

Explanation:

1)

In the first statement a new object of the class AirConditioner whose reference is assigned to the officeAC. new is a keyword which creates an object of the class.

Next statement uses the method turnOn(). Reference to the new object officeAC is used to invoke this method turnOn().

2) The first two statements works the same as in 1)

The last statement invokes a method setTemp() using the reference variable and passes the value 69 to this method to set the desired temperature.

Write the 8-bit signed-magnitude, two's complement, and ones' complement representations for each decimal number: +25, + 120, +

pshichka [43]

Answer:

Let's convert the decimals into signed 8-bit binary numbers.

As we need to find the 8-bit magnitude, so write the powers at each bit.

Sign -bit 64 32 16 8 4 2 1

+25 - 0 0 0 1 1 0 0 1

+120- 0 1 1 1 1 0 0 0

+82 - 0 1 0 1 0 0 1 0

-42 - 1 0 1 0 1 0 1 0

-111 - 1 1 1 0 1 1 1 1

One’s Complements:

+25 (00011001) – 11100110

+120(01111000) - 10000111

+82(01010010) - 10101101

-42(10101010) - 01010101

-111(11101111)- 00010000

Two’s Complements:

+25 (00011001) – 11100110+1 = 11100111

+120(01111000) – 10000111+1 = 10001000

+82(01010010) – 10101101+1= 10101110

-42(10101010) – 01010101+1= 01010110

-111(11101111)- 00010000+1= 00010001

Explanation:

To find the 8-bit signed magnitude follow this process:

For +120

put 0 at Sign-bit as there is plus sign before 120.

Put 1 at the largest power of 2 near to 120 and less than 120, so put 1 at 64.

Subtract 64 from 120, i.e. 120-64 = 56.

Then put 1 at 32, as it is the nearest power of 2 of 56. Then 56-32=24.

Then put 1 at 16 and 24-16 = 8.

Now put 1 at 8. 8-8 = 0, so put 0 at all rest places.

To find one’s complement of a number 00011001, find 11111111 – 00011001 or put 0 in place each 1 and 1 in place of each 0., i.e., 11100110.

Now to find Two’s complement of a number, just do binary addition of the number with 1.

Use the loop invariant (I) to show that the code below correctly computes the product of all elements in an array A of n integer

NeTakaya

Answer:

Given Loop Variant P = a[0], a[1] ... a[i]

It is product of n terms in array

Explanation:

The Basic Step: i = 0, loop invariant p=a[0], it is true because of 'p' initialized as a[0].

Induction Step: Assume that for i = n - 3, loop invariant p is product of a[0], a[1], a[2] .... a[n - 3].

So, after that multiply a[n - 2] with p, i.e P = a[0], a[1], a[2] .... a[n - 3].a[n - 2].

After execution of while loop, loop variant p becomes: P = a[0], a[1], a[2] .... a[n -3].a[n -2].

for the case i = n-2, invariant p is product of a[0], a[1], a[2] .... a[n-3].a[n-2]. It is the product of (n-1) terms. In while loop, incrementing the value of i, so i=n-1

And multiply a[n-1] with p, i.e P = a[0].a[1].a[2].... a[n-2].

a[n-1]. i.e. P=P.a[n-1]

By the assumption for i=n-3 loop invariant is true, therefore for i=n-2 also it is true.

By induction method proved that for all n > = 1 Code will return product of n array elements.

While loop check the condition i < n - 1. therefore the conditional statement is n - i > 1

If i = n , n - i = 0 , it will violate condition of while loop, so, the while loop will terminate at i = n at this time loop invariant P = a[0].a[1].a[2]....a[n-2].a[n-1]
