Laboratory Report 4

<h5>Excess 5 to Binary Coded Decimal</h5>
<p><i>This Project was made using EdSim51DI like the other Laboratory Experiments. You may download the tool in their <a href="https://www.edsim51.com/8051simulator/edsim51di.zip" target="_blank">site here</a>.</i></p>
<br />
<p>The setup of the project is different from the default. So first, we need to setup the Dynamic Interface of the EdSim51DI by clicking the DI button located near the LEDs.</p><br />
<p>This will be the default settings of the EdSim51DI.</p>
<img src="https://i.imgur.com/lSNlI4K.png" alt="Default settings" class="img-fluid" />
<br /><br />
<p>This will be the new settings of the EdSim51DI.</p>

Machine Problem 2

Create a simple Python program for linear regression using randomly generated data sets, which is scattered around a line with a slope of 2 and intercept of -2. Present the regression model coefficient and intercept, coefficient of determination (R2), and root mean squared error (RMSE).

<h5>Code: </h5>

Machine Problem 4

2. Ask for the Base and Exponent and output the computed power

<pre class='lang-cpp line-numbers'><code>#include &lt;iostream&gt;
using namespace std;
int main()
{
 int, base, exp;
 float pow=1;
 cout&lt;&lt;&quot;base: &quot;;
 cin&gt;&gt;base;
 cout&lt;&lt;&quot;exponent: &quot;;
 cin&gt;&gt;exp;
 
 if (exp==0)
 {
  pow=1;
 }
 else if (exp&lt;0)
 {
  int tempexp=exp*-1;
  while (tempexp&gt;0)
  {
   pow*=base;

  while (tempexp&gt;0)
  {
   pow*=base;
   tempexp=tempexp-1;
  }
 }
 
 cout&lt;&lt;pow;
}
</code></pre>

7. Determine modulo division given the dividend and divisor as inputs without using modulo (%) operation

<pre class='lang-cpp line-numbers'><code>start

input dividend
input divisor

tempdivisor=divisor
tempdividend=dividend

while(tempdivisor<=tempdividend)
	tempdividend=tempdividend-tempdivisor
endwhile

print tempdividend

end
</code></pre>

1. Determine the computed Power given Base and Ex (exponent) as user input without using Multiplication. You may use successive Addition.

<pre class='lang-cpp line-numbers'><code>start
int fact = 1

print "Enter a positive integer: "
input num

if (num==0)
	print "invalid"

elseif (num&lt;0)
	print "NA"

elseif (num&gt;0)
	while (i&lt;=num)
		fact=fact * i
		i++
	endwhile
	print factorial
endif

end</code></pre>

Activity 2

1. Ask a user for 20 numbers, must store in an array. Determine the largest and smallest number.

<h5>Code: </h5>
<pre class='lang-cpp line-numbers'><code>start
	int size=20
	int rane[size]
	int largest, smallest
	print “Enter 20 numbers:”
	for (int a=0; a&lt;size; a++)
		input rane[a]
	end for
	largest=rane[0]
	smallest=rane[0]
	for (int a=0; a&lt;size; a++)
		if (largest&lt;rane[a])
			largest=rane[a]
		end if
		if (smallest&gt;rane[a])
			smallest=rane[a]

Experiment 7

Programming Paradigms/Object Oriented Design

<h5><b>Prelab</b></h5>
<p>3. Class B extends class A. Class B defines an _str_ method that returns the string representation of its instance variables. Class B defines a single instance variable named age, which is an integer. Write the code to define the _str_ method for class B. This method should return the combined string information from both classes. Label the data for age with the string "Age: ".</p>
<pre class="line-numbers lang-python"><code>class A:
    def __init__(self):
        self.message = &quot;This is from Class A\n&quot;
    
    def __str__(self):
        return self.message


class B(A):
    def __init__(self):
        super().__init__()
        self.age = 18

    def __str__(self):
        return super().__str__() + &quot;Age: &quot; + str(self.age)

b  = B()
print(b)</code></pre>
<br /><br />


<h5><b>Inlab</b></h5>
<p>4. The ATM program allows a user an indefinite number of attempts to log in. Fix the program so that it displays a popup message that the police will be called after a user has had three successive failures. The program should also disable the login button when this happens.</p>

Examples of Serial and Parallel I/O Communications

<h5>Serial I/O communication</h5><br />
<ol>
<li><strong>Universal Serial Bus (USB)</strong> - This will attach all sorts of external USB devices commonly includes external hard drive, printer and scanner, mouse and keyboard. With USB Type C, computers and smartphones now offer connections to each other.</li>
<li><strong>Ethernet</strong> - provides connection between an end device and a network. It can offer I/O speeds of up to 1000 Megabits per seconds. Some types includes Coaxial, RJ45  and the latest is the Fiber Optic cables.</li>
<li><strong>Peripheral Component Interconnect Express (PCIe)</strong> - Is a standard type of user interface link for internal interfaces like Graphics Processing Units. The PCI Express protocol, as well as other equipment, enables high speed connectivity between devices and motherboard.</li>
<li><strong>Firewire (IEEE 1394)</strong> - Is a standard serial bus interface for high-speed communications and real-time I/O data transmission.</li>
<li><strong>Serial Advanced Technology Attachment Express(SATAe)</strong> - This is an interface which is used to link ATA hard drives to the motherboard of a device. This supports both SATA and PCIe storage devices.</li>
</ol>
<br /><br />

<h5>Parallel I/O communication</h5><br />
<ol>
<li><strong>Parallel port</strong> - The parallel port is located on the back of computers that are compliant with IBM and is a 25-pin (DB-25 type) device interface typically used to link printers to the machine.</li>
<li><strong>Parallel Advanced Technology Attachment (PATA)</strong> - Parallel ATA (PATA), originally named AT Attachment, is a standard interface for attaching storage devices in computers such as disk drives, floppy disk drives, and optical disks.</li>
<li><strong>Front-side Bus (FSB)</strong> - A front-side bus (FSB) is a network networking bus that was mostly in computers built on Intel-chips. It carries data between the CPU and memory controller hub known as northbridge.</li>
<li><strong>IEEE 1284</strong> - is a standard which specifies simultaneous I/O parallel communication between computers and other devices. It was initially established by Centronics in the 1970s and became commonly recognized as the Centronics terminal, both before and after its standardization with IEEE.</li>
<li><strong>Small Computer System Interface (SCSI)</strong> - is more widely used with hard disk drives and cassette drives although it can connect a large range of other items, including scanners and CD players, but not all controllers can accommodate these items.</li>
</ol>

3. Ask the user for the value of N and output the nth term of the fibonacci series

<pre class='lang-cpp line-numbers'><code>#include &lt;iostream&gt;
using namespace std;
int main()
{
 int a=0, b=1, ctr=1, n;
 int fib;
 
 cin&gt;&gt;n;
 
 if (n&lt;0)
 {
  cout&lt;&lt;&quot;out of range&quot;;
 }
 else if(n==1)
 {
  cout&lt;&lt;a;
 }
 else if(n==2)
 {
  cout&lt;&lt;b;
 }
 else
 {
  while(ctr&lt;=n)
  {
   fib=a+b;
   a=b;
   b=fib;
   ctr++;
   cout&lt;&lt;fib&lt;&lt;&quot; &quot;;
  }
 }
}</code></pre>

5. Ask for a range of number (lower limit and upper limit), and output all Prime numbers from the input range.

<pre class='lang-cpp line-numbers'><code>start

input LL, UL

if(LL>UL)
temp=LL
LL=UL
UL=temp
endif

num=LL
while (num<=UL)
	factor=2
prime=1
	while(factor<=num/2)
		if (num%factor==0)
			prime=0
			factor=num
		endif
		factor++
	endwhile

	if (prime==1)
		print num
	endif
	num++
endwhile

end</code></pre>

2. Determine the factorial of an input number without using multiplication. Use successive addition

<pre class='lang-cpp line-numbers'><code>start
int factorial
int i=1, ifact=1

print "Enter a number: "
input factorial

int tempfact=factorial
int factstore=factorial-1

if (factorial==0)
	print "invalid"
elseif (factorial&lt;0)
	print "Out of range"
else
	while (i&lt;=factorial)
		int tempnew=tempfact
		ifact=1
		while	(ifact&lt;factstore)
			tempfact=tempfact+tempnew
			ifact++
		endwhile
		factstore--
		i++
	endwhile
	print tempfact

end</code></pre>

2. Ask a user for 20 numbers, must store in an array. Determine the mean.

<h5>Code: </h5>
<pre class='lang-cpp line-numbers'><code>start
	int sum=0, mean=0

	for (int a=0; a&lt;size; a++)
		sum = sum+rane[a]
	end for
	
	mean=sum/size	

	print “the mean is “, mean
end</code></pre>
<br /><br />

3. Ask the user for 10 numbers, then reverse the order of the number in the array.

<h5>Code: </h5>
<pre class='lang-cpp line-numbers'><code>start

	int size=10, b=size-1
	int gtech[size]
	int temp
	
	print “Enter 10 numbers:”

	for (int a=0; a&lt;size; a++)
		input gtech[a]
	end for
	
	for (int a=0; a&lt;b; a++)
		gtech[a]=gtech[a]+gtech[b]
		gtech[b]=gtech[a]-gtech[b]
		gtech[a]=gtech[a]-gtech[b]
		b--;
end for

	print “the reverse of the numbers is: ”
	for (int a=0; a&lt;size; a++)
		print gtech[a], “   “
end for
