Write a program that reads a string and outputs the number of times each lowercase vowel appears in it. Your program must contain a function with one of its parameters as a string variable and return the number of times each lowercase vowel appears in it. Also write a program to test your function. (Note that if str is a variable of type string, then str.at(i) returns the character at the ith position. The position of the first character is 0. Also, str.length() returns the length of the str, that is, the number of characters in str.)
Answers
Answer:
Here the code is given as follows,
Explanation:
#include <iostream>
#include <string>
using namespace std;
void Vowels(string userString);
int main()
{
string userString;
//to get string from user
cout << "Please enter a string: ";
getline(cin,userString,'\n');
Vowels(userString);
return 0;
}
void Vowels(string userString)
{
char currentChar;
//variables to hold the number of instances of each vowel
int a = 0, e = 0, i = 0, o = 0, u = 0;
for (int x = 0; x < userString.length(); x++)
{
currentChar = userString.at(x);
switch (currentChar)
{
case 'a':
a += 1;
break;
case 'e':
e += 1;
break;
case 'i':
i += 1;
break;
case 'o':
o += 1;
break;
case 'u':
u += 1;
break;
default:
break;
}
}
// to print no of times a vowels appears in the string
cout << "Out of the " << userString.length() << " characters you entered." << endl;
cout << "Letter a = " << a << " times" << endl;
cout << "Letter e = " << e << " times" << endl;
cout << "Letter i = " << i << " times" << endl;
cout << "Letter o = " << o << " times" << endl;
cout << "Letter u = " << u << " times" << endl;
}
Hence the code and Output.
Please enter a string
Out of the 16 characters you entered.
Letter a = 2 times
Letter e = 1 times
Letter i = 0 times
Letter o = 1 times
Letter u = 0 times.

Discuss at least 1 Microsoft Windows security features that could protect data?
Answers
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

A) Why should assembly language be avoided for general application development?
B) Under what circumstances would you argue in favor of using assembly language for developing an assembly language program?
C) What are the advantages of using a compiled language over an interpreted one?
D) Under what circumstances would you choose to use an interpreted language?
Answers
Answer:
(A) Assembly language should be avoided for general application development for the following reasons:
i. It is difficult to write assembly language codes. It does not contain many tools and in-built functions to help with the development of these applications.
ii. Since general application development requires that the application be machine independent, writing such applications in assembly language (which is a low level, machine dependent language) might be a pain as it would require that the writer have sufficient knowledge of hardware and operating systems.
(B) The following are the circumstances where assembly language should be used:
i. Assembly languages are low level languages that are very close to machine languages that the machine or processor understands. Therefore, when writing codes for programs that should directly communicate with the processor, assembly language should be used.
ii. Since assembly language codes are machine dependent, when there is a need to write applications for target machines, they should be used.
iii. If there is a need to have very great control of certain features of your application and resources to be consumed such as amount of RAM, clock speed e.t.c, assembly languages are a great tool.
(C) Some of the advantages of compiled language over an interpreted language are:
i. Compiled languages are way faster than interpreted languages because the compiled languages are converted directly into native machine codes that are easy for the processor to execute. Put in a better way, with compiled languages, codes are compiled altogether before execution and therefore reduces the overhead caused at run time. Interpreted languages on the other hand executes codes line after line thereby increasing the overhead at run time.
ii. Since codes are compiled first before execution in compiled languages, nice and powerful optimizations can be applied during the compilation stage.
(D) Interpreted languages could be chosen over compiled languages for the following reasons:
i. Interpreted languages are much more flexible and easier to implement than compiled languages as writing good compilers is not easy.
ii. Since interpreters don't need to convert first to intermediary codes as they execute these codes themselves, programs built with interpreters tend to be platform independent.

A group of computer scientists wants to create a fixed-length compression algorithm. The simplest way to achieve compression is to use a fixed-length code generator. The idea behind this type of code generator is to assign a fixed-length bit sequence to each symbol of the alphabet. As part of this group of computer scientists, your goal is to write a program to determine the alphabet used by the message to be compressed (set of different characters in the input message), and the frequency of each symbol in the alphabet, using conditionals, loops, and arrays.

Answers
Answer:
Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is
Explanation:
The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."
This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.
Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.
And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters

Answers
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.

The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.

For this activity, you will practice being both proactive and reactive to bugs. Both are necessary to get rid of errors in code.
Proactive:
Log in to REPL.it and open your Calculator program that you built in Unit 5.
In the index.js file, type and finish the following block of code that validates the input to make sure both are numbers (not letters or symbols):
try{
if (isNaN(…) || isNaN(…)){
throw …
}
else{
document.getElementById("answer").innerHTML = num1 + num2;
}
}
catch(e){
document.getElementById("answer")…
}
(Note: The || symbol is used in JavaScript to mean or . You can find this key to the left of the Z key if you’re using a PC or directly above the Enter key if you’re using a Mac.)
Add the finished code above to the correct place in your add() function. Make sure to delete this line since we moved it into the try block:
document.getElementById("answer").innerHTML = num1 + num2;
Paste the same code into the subtract() , multiply() , and divide() functions, making the necessary changes. Be careful with your divide() function since you already have an extra if else statement checking for a division by 0 mistake. (Hint: Cut and paste the entire if else statement inside the else block of your try statement.)
Test your program by typing in letters or symbols instead of numbers. Make sure you get the appropriate error message. (Note: The function is not supposed to check whether the text field is empty, only whether it contains non-numbers.)
When you are finished, share the link to your webpage with your teacher by clicking on the share button and copying the link.
Reactive:
The following Python program should print the sum of all the even numbers from 0 to 10 (inclusive), but it has two bugs:
x = 0
sum = 0
while x < 10:
sum = sum + x
x = x + 1
print(sum)
Complete a trace table and then write a sentence or two explaining what the errors are and how to fix them. You can choose whether to do the trace table by hand or on the computer. Turn in your trace table and explanation to your teacher.
