When calling a function with arguments that should be modified, the __________ of those arguments are passed.
ad-work [718]

Answer:

Addresses.

Explanation:

An argument can be defined as a value that can be passed to a function.

Simply stated, an argument is a value that must be passed into a function, subroutine or procedure when it is called. This value can be passed to a function either by reference or by value.

This ultimately implies that, an argument which is also a parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.

Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.

When calling a function with arguments that should be modified, the addresses of those arguments are passed. This is simply because the argument is an address or pointer in itself and as such the function parameter being called must be a pointer.

In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.

Hence, all instance variables that have been used or declared in any superclass would be present in its subclass object.

Ivanshal [37]

Answer:

See explaination for the program code

Explanation:

The Programming code:

inFile = open("stuff.txt", "r")

num = []

Sum = 0

for val in inFile.readlines():

value = val.split(",")

Sum = Sum + int(value[1])

print("Sum of second number on every line in the file is: ", Sum)

inFile.close()

Piecewise functions are sometimes useful when the relationship between a dependent and an independent variable cannot be adequat
Andru [333]

Answer:

//Set a piecewise function v(t).

function v = vpiece(t)

//Set the condition first for t.

if ((0<=t)and(t<=8))  //Set if condition

// first equation of velocity.

   v = 10*t^2 - 5*t;

//Set the condition second for t.

elseif((8<=t)and(t<=16))  //Set elseif condition

//second equation of velocity.

v = 624 - 5*t;

//set the condition third for t.

elseif((16<=t)and (t<=26))  //Set elseif condition  

//third equation of velocity.

v = 36*t + 12*(t - 16)^2;

//Set the fourth condition for t.

elseif t>26

//fourth equation of velocity.

v = 2136*exp(-0.1*(t-26));

//Last condition.

else

//fifth equation of velocity.

v = 0;

//End of the function v.

end

//set a variable and initialize it to 0.

a=0;

//Starting the loop.

for j = -5: 0.5 : 70

//Increment the value of a by 1.

a = a + 1;

t(a) = j;

v(a) = vpiece(t(a));

//End of for loop.

end

//Plot the graph between t and v.

plot(t,v)

//Write the label for the x-axis.

xlabel('t')

//Write the label for the y-axis.

ylabel('velocity')

//Write the title of the plot.

title('Plot of velocity vs t')

Explanation:

Firstly, we set the piecewise method.

Then we set the first condition, after that we apply the condition of velocity.

Then we set the second condition, after that we apply the condition of velocity.

Then we set the third condition, after that we apply the condition of velocity.

Then we set the fourth condition, after that we apply the condition of velocity.

Then we set the last or fifth condition, after that we apply the condition of velocity.

Then we set the variable "a" to 0.

Then start the loop and increase the value by 1.

And after all, we write the title of the plot.
