Write the function definition for a function called list_total that accepts a list of integers
uranmaximum [27]

Answer:

def list_total(numbers):

   sum_of_numbers = 0

   for number in numbers:

       sum_of_numbers += number

   return sum_of_numbers

Explanation:

So, to define a function, the syntax is simply:

def functionName(arguments here):

   # code

So to define a function called "list_total" which accepts a list of integers, you write:

"

def list_total(numbers):
   # code

"

any the "numbers" is a parameter, and it's just like any variable, so you can name it anything besides keywords. I just named it "numbers" since it makes sense in this context, you could also write "integers" instead and it would be just as valid, and may be a bit more specific in this case.

Anyways from here, the initial sum should be equal to 0, and from there we add each number in the list to that initial sum. This can be done by initializing a variable to the value "0" and then traversing the list using a for loop. This can be done as such:

"

def list_total(numbers):

   sum_of_numbers = 0

   for number in numbers:

       # code

"

So for each element or integer in the list "numbers" the for lop will run, and the variable "number" will contain the value of the current element it's on.

So we can add the "number" to the sum_of_numbers as such:

sum_of_numbers = sum_of_numbers + number

but there is a shorter way to do this, and it's represented as:

sum_of_numbers += sum_of_numbers

which will do the same exact thing. In fact this works for any mathematical operation for example:

a *= 3

is the same thing as

a = a * 3

and

a /= 3

is the same thing as

a = a / 3

It's the same thing, but it's a much shorter and more readable notation.

Anyways, this code will go in the for loop to almost finish the code

"

def list_total(numbers):

   sum_of_numbers = 0

   for number in numbers:

       sum_of_numbers += number

"

The last thing is to return this value, and this is simply done by using the syntax:

"return {value here}"

and since the sum_of_numbers has the value, we write

"return sum_of_numbers"

at the end of the function, which is very very important, because when you use the return keyword, you end the function, and return whatever value is next to the return to the function call

So to finish the code we just add this last piece to get:

"

def list_total(numbers):

   sum_of_numbers = 0

   for number in numbers:

       sum_of_numbers += number

   return sum_of_numbers

"

Why do we need multitasking functionality in an Operating System?
Leokris [45]

Answer:

Multitasking is a process in which we do multiple task at a time.    

In computing system, multitasking is the concept of performing different types of multiple task and process over a certain period of time by executing simultaneously.

Operating system basically allow various task to run simultaneously by the user. In an operating system, each task consume storage system and all the other resources.

Multitasking function facilitate memory isolation in the processor and also supported different levels of security system in the operating system. For example, "a programmer working on any program in a system and as well as listening the music then, it perform multiple task at the same time".

Suppose you have a class called Child with an instance data value called weight and height. Then it has a method called doubleWe
alexira [117]

Answer:

Explanation:

The following code is written in Java. I recreated the entire Child class as described with the instance variables and the doubleWeight method. Then created the getter and setter methods for both the weight and height variables.

class Child {

   double weight, height;

   public double doubleWeight() {

       double superWeight = weight * height;

       return superWeight;

   }

   public double getWeight() {

       return weight;

   }

   public void setWeight(double weight) {

       this.weight = weight;

   }

   public double getHeight() {

       return height;

   }

   public void setHeight(double height) {

       this.height = height;

   }

}
