6.23 LAB: Flip a coin
Define a function named CoinFlip that returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls function CoinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0.
Hint: Use the modulo operator (%) to limit the random integers to 0 and 1.
Ex: If the random seed value is 2 and the input is:
3
the output is:
Tails
Heads
Tails
Note: For testing purposes, a pseudo-random number generator with a fixed seed value is used in the program. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used for each test case.
The program must define and call the following function:
string CoinFlip()
The program that defines a function named CoinFlip that returns "Heads" or "Tails" according to a random value 1 or 0 is given below:
The Program#include <iostream>
#include <cstdlib>
#include <ctime>
std::string CoinFlip() {
int randomValue = std::rand() % 2;
return (randomValue == 1) ? "Heads" : "Tails";
}
int main() {
std::srand(std::time(0)); // Seed the random number generator
int numFlips;
std::cin >> numFlips;
for (int i = 0; i < numFlips; ++i) {
std::cout << CoinFlip() << std::endl;
}
return 0;
}
We use std::rand() to generate a random number between 0 and RAND_MAX, and limit it to 0 or 1 with the % operator.
The CoinFlip() function returns "Heads" or "Tails". In main(), we seed the random number generator with std::srand(std::time(0)).
To ensure unique random values, we call CoinFlip() function in a loop after taking user input for the desired number of coin flips. Finally, return 0 for program success.

Explanation:
Students are often asked to write term papers containing a certain number of words. Counting words in a long paper is a tedious task, but the computer can help. Write a program WordCount.java that counts the number of words, lines, and total characters (not including whitespace) in a paper, assuming that consecutive words are separated either by spaces or end-of-line characters.
Answer:
Explanation:
The following code is written in Java. It is a function that takes the file name as a parameter. It then reads the file and counts the lines, words, and characters (excluding whitespace), saves these values in variables and then prints all of the variables to the console in an organized manner.
import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Scanner;
public static void countText(String fileName) throws FileNotFoundException {
int lines = 0;
int words = 0;
int characters = 0;
File myObj = new File(fileName);
Scanner myReader = new Scanner(myObj);
while (myReader.hasNextLine()) {
String data = myReader.nextLine();
lines += 1;
for (int x = 0; x < data.length(); x++) {
if (data.charAt(x) != ' ') {
characters += 1;
} else {
words += 1;
}
}
System.out.println(data);
}
System.out.println("File Contains:");
System.out.println(lines + " Lines");
System.out.println(words + " Words");
System.out.println(characters + " Characters");
myReader.close();
}
Following are Java Programs to count words, characters, and lines from the file.
Program to Count words into the file:import java.io.*;//import package
import java.util.*;//import package
public class WordCount//defining the class WordCount
{
public static void main(String[] a) throws IOException //defining main method that uses the throws keyword for catch Exception
{
int wordCount=0,totalChar=0,lineCount = 0;//defining integer vaiable
String sCurrentLine;//defining String vaiable
File f = new File("words.txt");//creating the file class object
if(f.exists())//defining if block that checks file
{
Scanner sa = new Scanner(f);//creating Scanner class object that takes file as input
while (sa.hasNextLine())//defining loop that checks elements in file
{
sCurrentLine = sa.nextLine();//using String vaiable that holds input value
lineCount++;//incrementing the lineCount value
String words[] = sCurrentLine.split("\\s+");//defining String vaiable as array that holds split value of sCurrentLine vaiable
wordCount = wordCount + words.length;//ussing wordCount vaiable to hold length value
for(int i=0; i<words.length; i++)//defining loop that counts total length and store its value in totalChar
{
totalChar = totalChar + words[i].length();//holding length in totalChar vaiable
}
}
System.out.println("Total lines = "+lineCount);//printing the line values
System.out.println("Total words = "+wordCount);//printing the words values
System.out.println("Total chars = "+totalChar);//printing the Character values
}
}
}
Output:
Please find the attached file.
Program:

How to explain the tableHere are some tips on how to effectively organize content in tables:
Determine the purpose of the table: Before creating a table, identify the purpose and the message you want to convey. Determine what kind of information you want to include in the table and how it can be best presented.
Use clear and concise headings: Use headings that are brief and clearly describe the content in each column or row. Headings help the reader to quickly identify the content and understand the structure of the table.
Keep the table simple and easy to read: Avoid using too many colors, borders, and font styles. Keep the table clean and simple, with clear lines and easy-to-read fonts.
Use consistent formatting: Ensure that the table formatting is consistent throughout the document. Use the same font size, style, and color for all the tables.
Group similar items together: Organize the table by grouping similar items together. This makes it easier for the reader to compare and analyze the information.
Use appropriate units of measure: Use appropriate units of measure for the data presented in the table. For example, use dollars for financial data, and use percentages for statistical data.
Use appropriate table type: Choose the appropriate table type to present the data. There are various types of tables such as comparison tables, frequency tables, and contingency tables, among others. Choose the type that best suits your data.
Consider accessibility: Ensure that the table is accessible to everyone, including those with visual impairments. Use alt text to describe the content of the table, and ensure that the table is navigable with a screen reader.

5. Return the authors whose first names are shorter than all last names.
6. Return the first 10 borrowing which late fee is unknown.
How do I write these using Oracle SQL sub selects?
Answer:
To write these queries using Oracle SQL sub selects, the following syntax can be used:
1. Return the card number, first name, last name, and average late fee of each customer. Name this column as "Fee".
SELECT card_number, first_name, last_name, AVG(late_fee) AS "Fee"
FROM customers
GROUP BY card_number, first_name, last_name;
2. Return the authors whose first names are shorter than all last names.
SELECT *
FROM authors
WHERE LENGTH(first_name) < ALL (SELECT LENGTH(last_name) FROM authors);
3. Return the first 10 borrowing which late fee is unknown.
SELECT *
FROM borrowings
WHERE late_fee IS NULL
AND ROWNUM <= 10;
Explanation:
In these queries, sub selects are used to select specific data from a table and use it in the main query. For example, in the second query, a sub select is used to select the length of all last names from the authors table, and this data is then used in the main query to filter the authors whose first names are shorter than all last names. In the third query, a sub select is used to filter the borrowings with unknown late fees, and the main query is used to limit the result to the first 10 rows.

Mathematically, 10+2 is 12. So your answer is correct. However, if you are trying to write a code that adds 10 + 2, you may need to troubleshoot the code to find where the bug is.
What is troubleshooting?Troubleshooting is described as the process through which programmers detect problems that arise inside a specific system. It exists at a higher level than debugging since it applies to many more aspects of the system.
As previously stated, debugging is a subset of troubleshooting. While debugging focuses on small, local instances that can be identified and fixed in a single session, troubleshooting is a holistic process that considers all of the components in a system, including team processes, and how they interact with one another.

Suppose you have n classes that you want to schedule in rooms. Each class has a fixed time interval at which it is offered, and classes whose times overlap cannot be scheduled in the same room. There are enough rooms to schedule all the classes. Design a O(n log n) time algorithm to find an assignment of classes to rooms that minimizes the total number of rooms used.
Answer:
Function schedule( list of tuple of start and end times, class available)
class_list = create list of class from class available
for items in time_list:
if items is not same range as time_list[-1]:
newdict[items] = class_list[0]
print class time: class venue
elif items is same range as time_list[-1]:
