Answer:

GOF refers to the gang of four pattern that are generally consider the basic for all the other patterns. Design pattern are basically provide the solution to the software design to resolve all problems that are associated with the development of real world applications.

GOF Design pattern implemented the parts of the re-usable object oriented software applications. The main aim of design pattern is to pass all the structural design pattern. Design pattern is the most powerful and helpful tool for the software developer and architecture.

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.

Define the term algorithm and describe how programmers use algorithms when designing a program.
horrorfan [7]
An algorithm is a set of instructions designed to perform a specific task. This can be a simple process, such as multiplying two numbers, or a complex operation, such as playing a compressed video file. Search engines use proprietary algorithms to display the most relevant results from their search index for specific queries. In many cases, there are multiple ways to perform a specific operation within a software program. Therefore, programmers usually seek to create the most efficient algorithms possible. By using highly-efficient algorithms, developers can ensure their programs run as fast as possible and use minimal system resources. Of course, not all algorithms are created perfectly the first time. Therefore, developers often improve existing algorithms and include them in future software updates. When you see a new version of a software program that has been "optimized" or has "faster performance," it most means the new version includes more efficient algorithms.

4. How many times will the print statement be executed within the following nested for loops? Briefly explain how or show the ma
HACTEHA [7]

Print statements are used to display outputs

The number of times the nested loop will be executed is 43200

<h3>What are nested for loops?</h3>

Nested for loops are loops that are placed within another loop or loops

From the statement, we have the following loop conditions:

h = 1; h <= 12, m = 0; m <= 59 and s = 0; s <= 59

The above means that:

  • h = 12 --- the outer loop will be executed 12 times
  • m = 60 --- the middle loop will be executed 60 times
  • s = 60 --- the inner loop will be executed 60 times

So, the number of times the nested loop will be executed is:

Count = 12*60 *60

Count = 43200

Hence, the number of times the nested loop will be executed is 43200
