Answer:

a) 17, b) 27, c) 30, d) 12

Explanation:

a) x * a

3.4 * 5 = 17

b) static_cast<int>(x) * static_cast<int>(z)

Casting a value to int makes it an integer. The above one equals int(3.4) * int(9.1) = 3 * 9 = 27

c) static_cast<int>(x * z)

Casting a value to int makes it an integer. The above one equals int(3.4 * 9.1) = int(30.94) = 30

d) static_cast<double>(b)

12

What is the difference between compliled and intebrated language?
Nady [450]

Answer:  

A compiled language is a programming language whose implementations are typically compilers and not interpreters. In this language, once the program is compiled it is expressed in the instructions of the target machine. There are at least two steps to get from source code to execution. While, an interpreted language is a programming language whose implementations execute instructions directly and freely, without previously compiling a program into machine-language instructions. While in this language, the instructions are not directly executed by the target machine. There is only one step to get from source code to execution.

I hope this helps.

Ivenika [448]

However, sitting in a corner of the store, a hacker had just placed up an open “rogue” wireless hotspot posing as the coffee shop’s wireless network. When Sarah logged onto her bank’s website, the hacker hijacked her session and gained access to her bank accounts. Another term for rogue wireless hotspots exists as “evil twin” hotspots.

<h3>What is meant by wireless network?</h3>

A computer network is referred to as a wireless network if radio frequency (RF) links are used to connect network nodes. A common solution for households, companies, and telecommunications networks is wireless networking. Wi-Fi is a wireless networking technology that enables printers and video cameras to connect to the Internet as well as computers (laptops and desktops), mobile devices (smart phones, wearables, etc.), and other devices.

Increased Mobility: Wireless networks give mobile users access to real-time data, enabling them to move freely across the premises of your firm without losing network connectivity. This improves collaboration and production across the entire organisation, which is not achievable with traditional networks.

Q1). Write a python program to pass a list to a function and double the odd values and half even values of a list and display li
zepelin [54]

Answer:

\textsf{\large{\underline{Solution}:}}

The given problem is solved using language - Python.

def f(x):

   new_list=[]

   for i in x:

       if i%2==0:

           new_list.append(i//2)

       else:

           new_list.append(i*2)

   return new_list

   

my_list=list(range(1,6))

print('Original List:',my_list)

my_list=f(my_list)

print('Modified List:',my_list)

\textsf{\large{\underline{Logic}:}}

  1. Create a new list.
  2. Iterate over the list passed into the function.
  3. Check if the element is even or not. If true, append half the value of element in the list.
  4. If false, append twice the value of the element in the list.
  5. At last, return the new list.

There is another way of doing this - By using map() function.

—————————————————————————————

def f(x):

   return list(map(lambda x:x//2 if x%2==0 else 2*x,x))

   

my_list=list(range(1,6))

print('Original List:',my_list)

my_list=f(2my_list)

print('Modified List:',my_list)

—————————————————————————————

\textsf{\large{\underline{O{u}tput}:}}

Original List: [1, 2, 3, 4, 5]

Modified List: [2, 1, 6, 2, 10]
