Answer:
The system call is the programming way for executing the requesting the services in the program from kernel in the particular operating system.
The main purpose of the system call in the operating system is that it basically provide the different types of the services to the users by using the API (Application program interface) system.
It basically provide the interface for allowing the users to request the services between the operating system and a processor. In the linux there are basically three types of system call are as follows:
Answer:
The solution code is written in Python.
- def mult2_diff(lst):
- num_list = []
-
- for x in lst:
- num_list.append(x * 2)
-
- diff = num_list[0]
- for i in range(1, len(num_list)):
- diff = diff - num_list[i]
-
- print(diff)
Explanation:
Firstly, based on the requirement stated in the question, define a function <em>mult2_diff() </em>that takes one argument, <em>lst</em>, which is a list of numbers (Line 1).
This function is expected to multiply each number in the list by two and then followed with computing the difference. To do so, let's try to attempt the first function task, multiplying numbers. Create a new list, num_list, to hold the multiplied numbers (Line 2). Use a for loop to traverse through each number in the input list, <em>lst</em>, and multiply each of them by two and add it to the <em>num_list </em>(Line 4-5).
To attempt the second function task, create another variable, <em>diff</em>, to hold the value of calculated difference between the numbers in the <em>num_list</em>. Initialize <em>diff </em>with the first number in the <em>num_list</em>. Use a another for-loop to traverse through each number in the num_list starting with second index, <em>1</em>, and calculate the difference between the <em>diff </em>and the current number extracted from the <em>num_list </em>through indexing.
At last print the output of <em>diff</em> (Line 11).
Answer:
Hi,
The best option in the list is <u>stop posting her e-mail address on newsgroups.</u>
Explanation:
Unwanted e-mail is categorized as a spam email.These emails can not be entirely avoided because we use the Internet thus it is recommended that you filter them.A program called my email client can help to filter spam though in some cases, it might not be effective.
