Explanation:

This is because the for loop would go through each character in ' Welcome ' and print it. But with that there is end= '* ', and that would add a * to the end of each character and since there was print() on the third line that causes them to be on different lines. If you wanted them to be printed on the same line, you have to remove print()

Answers

Answer:

To calculate and display how much liters of water can store in a water tank that is 4m long, 2.5m wide and 1.5m tall, you can use the formula V = lbh, where V is the volume, l is the length, b is the width and h is the height. In this case, V = 42.51.5 = 15 cubic meters. As 1 cubic meter = 1000 liters, the tank can store 15,000 liters of water.

Answers

Python program takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day.

Here is a python code to implement the program:

def get_season(month, day):

   if month == "March":

       if day >= 20:

           return "Spring"

   elif month == "April" or month == "May":

       return "Spring"

   elif month == "June":

       if day <= 20:

           return "Spring"

       else:

           return "Summer"

   elif month == "July" or month == "August":

       return "Summer"

   elif month == "September":

       if day <= 21:

           return "Summer"

       else:

           return "Autumn"

   elif month == "October" or month == "November":

       return "Autumn"

   elif month == "December":

       if day <= 20:

           return "Autumn"

       else:

           return "Winter"

   elif month == "January" or month == "February":

       return "Winter"

   else:

       return "Invalid month"

You can use this function to get the season for any date by passing the month name as string and day as integer as input.

This code implements the logic to determine the season of a given date by checking the month and day. It uses if-elif statements to check the input month and day against the defined dates for each season. Based on the input, the function returns the corresponding season. If the input month is not recognized, the function returns an "Invalid month" message. This code can be used as a helper function in other programs that require season information for a given date.

The main difference between a repeat...until and a while...loop is that a repeat...until loop will always execute at least once, whereas a while...loop may never execute depending on the condition of the loop.

What is iteration ?

Iteration is the process of repeating a set of instructions or steps in order to reach a desired outcome. It is a fundamental concept in computer programming and is used to solve complex problems by breaking them down into smaller, more manageable chunks. Iteration allows for faster development and more efficient problem-solving.

Different type of iteration

1. While loop: A while loop is a loop that runs as long as a given condition is true.

2. For loop: A for loop is a loop that repeats a set number of times.

3. For-in loop: A for-in loop is used to iterate over a sequence such as a list, tuple, or dictionary.

4. Nested loop: A nested loop is a loop that is contained within another loop.

5. Recursive loop: A recursive loop is a loop that calls itself until a certain condition is met.

the protocol data unit encapsulation (pdu) is completed in which order?

Answers

Data, segments, packets, frames, and bits are all used. Every layer of data encoding is specified by the PDU encapsulation mechanism.

What is protocol data?

A protocol data unit is a discrete piece of information that is transferred among peers of a computer network in the field of telecommunications. It is made up of user data and protocol-specific control information. a set of guidelines or instructions for transferring data between computers and other electronic devices.

Computers need a preexisting agreement on the information's structure and how each side will send and receive it before they can share data.

The PDU is known as the Advertising Physical Channel PDU when a Bluetooth LE packet is sent over the periodic physical channel, the primary or secondary advertising physical channel, or both.

Define a class named History with the following public interface:
class History public: History (int n Rovs, int nCols): bool record(int r, int c); void display() const; o The constructor initializes a History object that corresponds to an Arena with Rows rows and Cols onlumns. You may assume (i.c., you do not have to check) that it will be called with a first argument that does not exceed MAXROWS and a second that does not exceed MAXCOLS, and that neither argument will he less than 1. o The record function is to be called to notify the History object that a poisoned blood vial has been dropped at a grid point that does not currently have a poisoned blood vial. The function returns false if row r, column c is not within the bounds specified by the History constructor; otherwise, it returns true after recording what it needs to. This function expects its parameters to be expressed in the same coordinate system as an Arena (e.g., row 1. column 1 is the upper-left-most position). o The display function clears the screen and displays the history grid as the posted programs do. This function does clear the screen, display the history grid, and write an empty line after the history grid; it does not print the Press enter to continue. after the display. (Note to Xcode users: It is acceptable that clearScreen( just writes a newline instead of clearing the screen if you launch your program from within Xcode, since the Xcode output window doesn't have the capability of being cleared.) The class declaration (with any private members you choose to add to support your implementation) must be in a file narned History.h, and the implementation of the History class's member functions must be in History.cpp. If you wish, you may add a public destructor to the History class. You must not add any other public members to the class. (This implies, for example, that you must not add a public default constructor.) The only member function of the History class that may write to cout is History::display.

Answers

Here is an implementation of the class "History" as described:

What is meant by public interface?

Public interface is a collection of protocols, methods, and properties that define a specific contract for a particular type of object. It allows objects to interact with each other in a standardized way, and is the primary means of communication between different objects and components within a programming language.

// History.h

class History {

public:

History(int nRows, int nCols);

bool record(int r, int c);

void display() const;

private:

int m_rows, m_cols;

char m_grid[MAXROWS][MAXCOLS];

csharp

Copy code

void clearScreen() const;

};

// History.cpp

#include "History.h"

#include <iostream>

History::History(int nRows, int nCols)

: m_rows(nRows), m_cols(nCols) {

for (int r = 0; r < m_rows; r++)

for (int c = 0; c < m_cols; c++)

m_grid[r][c] = '.';

}

bool History::record(int r, int c) {

if (r < 1 || r > m_rows || c < 1 || c > m_cols)

return false;

m_grid[r-1][c-1] = 'A' + (m_grid[r-1][c-1] - 'A' + 1) % 26;

return true;

}

void History::display() const {

clearScreen();

for (int r = 0; r < m_rows; r++) {

   for (int c = 0; c < m_cols; c++)

       std::cout << m_grid[r][c];

   std::cout << std::endl;

}

Therefore, above is the implementation of the class "History".

ow does this effect the ability of the forensic investigator to be able to collect the data for the case?

Answers

Forensic evidence is associated with higher confidence in guilty verdict

What are the most typical mistakes made when gathering evidence?

Not properly packing the evidence. Failure to keep a chain of custody. Not properly closing the box or marking the evidence. The place where the evidence was obtained was not documented. Failure to answer research questions, inability to validate results, skewed findings, lost resources, misleading recommendations and judgments, and injury to participants are all repercussions of improper data collection.

Making inadequate or indiscriminate analysis, as well as analysis to match the established legislation, are both unethical. Sometimes forensic experts publish the results without even opening the containers; a procedure known as ‘dry-labbing’. Forensic scientists’ findings and conclusions must be plain and unambiguous.
