Answer:

a. Partly True

b. True

Explanation:

(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.

For Visual Basics .Net, keyword "New" is used

For Python, "___new___" is used which allocates memory for instance and receives class as an argument.

For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.

(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.

1. Bluetooth

Elza [17]

Complete Question:

1. A wireless technology standard for exchanging data over short distances

2. A particular brand of mobile phone/PDA

3. A network that operates over a limited distance, usually for one or a few users

1. Bluetooth

2. PAN

3. Blackberry

Answer:

1. Bluetooth 2. Blackberry . 3. PAN

Explanation:

1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).

2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.

3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.

It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).

True / False<br> General purpose registers can be read and written by ML programs

Oduvanchick [21]

Answer: False

Explanation:

General purpose register cannot be read and written by the Ml program because when ever the instruction decode the input and output unit are invoke for data to read in the memory and it can written to the output device from the memory. General purpose register stored both the addresses and the data in the file. In some cases ML only reads with the hep of special algorithm function.

Description

lapo4ka [179]

Answer:

from datetime import time, datetime, timedelta, date

for _ in iter(list, 0):

t1 = input("Please enter time one: ")

t2 = input("Please enter time two: ")

if t1.isdigit() == True and (int(t1[:2])<=23 and int(t1[2:]) <= 59)\

and t2.isdigit() == True and (int(t2[:2])<= 23 and int(t2[2:])<=59):

time_1 = time(hour=int(t1[:2]), minute=int(t1[2:]))

time_2 = time(hour= int(t2[:2]), minute=int(t2[2:]))

if time_1 > time_2:

diff = datetime. combine (date. today( ), time_1) - datetime. combine(date. today ( ), time_2)

else:

diff = datetime. combine (date. today( ), time_2) -datetime. combine(date. today ( ), time_1)

diff_list = str(diff).split(":")

del diff_list[2]

diff_t = "". join (diff_list)

print(diff_t)

break

if t1.isdigit() == False or t2.isdigit() == False:

print("Military Time Forest Required: Bad input, try again.")

continue

elif int(t1[:2])> 23 or int(t2[:2])> 23:

print("Military Tine Format Required: Hours must be between 00 and 23, try again")

continue

elif int(t1[2:])> 59 or int(t2[2:])> 59:

print("Military Tine Format Required: Minutes must be between me and 59, try again")

continue

Explanation:

The python Datetime package is used to manipulate date and time, creating immutable Datetime objects from the various python data types like integer and string. The block of code above is a conditional for-loop statement that gets two user time value inputs and prints out the difference as a string in Military forest time format.
