Answer:

See Explaination

Explanation:

class MagicSquare():

def __init__(self,side):

self.side=side

self.two_dimension=[]

for row in range(1,side+1):

row_line=[]

for col in range(1,side+1):

row_line.append(0)

self.two_dimension.append(row_line)

def display(self):

row=0

col=int((self.side-1)/2)

for i in range(1,self.side**2+1):

self.two_dimension[row][col]=i

row-=1

col+=1

if row==-1:

row=self.side-1

if col==self.side:

col=0

if self.two_dimension[row][col]==0:

continue

else:

row+=1

if row==self.side:

row==0

for line in self.two_dimension:

for num in line:

print("{0:>3}".format(num),end=" ")

print()

def main():

for i in range(1,14,2):

square=MagicSquare(i)

square.display()

print("----------------------------------------------------")

if __name__ == '__main__':

main()

Letter Frequency Write a function that will take a string and return a count of each letter in the string. For example, "my dog
Nostrana [21]

Answer:

Check the explanation

Explanation:

Code to copy:

// ConsoleApplication7.cpp : Defines the entry point for the console application.

//

#include "stdafx.h"

#include <iostream>

#include <cstring>

#include <string>

using namespace std;

int * letterFrequency(char s[]);

int main()

{

  int *freq_letters;

  char *s = new char[100];

  freq_letters = new int[26];

  //To read the input string in order to find the frequency of each letter

  cout << "Enter a string: ";

  cin.getline(s, ' ');

  //call the function to find the occurrence of each alphabet

  freq_letters = letterFrequency(s);

  //Display the count

  cout << "Letter Frequency " << endl;

  for (int i = 0; i < 26; i++)

  {

      //Constriant to check if the letter appeared at least once in the string and so printing the frequency of its occurence

      if (freq_letters[i] != 0)

      cout << " " << static_cast<char>(i + 'a') << " " << freq_letters[i] << endl;

  }

  system("pause");

  return 0;

}

//Define the function to find occurrence of each letter in the input string

int * letterFrequency(char s[])

{

  int *occurrence_array;

//to store the output of occurrences for each alphabet

  occurrence_array = new int[26];

// to store the count of occurrence for each letter temporarily

  int letter_count;

  // for loop to check the occurrence for all 26 alphabets

 

  for (int i = 0; i < 26; i++)

  {

      letter_count = 0;

      for (int j = 0; j < strlen(s); j++)

      {

          /*comparing the ascii values of each alphabet with every character from the string by converting it to lower case i.e. case insensitive*/

          if (int('a') + i == int(tolower(s[j])))

              letter_count++;

      }

      occurrence_array[i] = letter_count;//To store the count calculated for each alphabet

  }

  return occurrence_array;

}

The following below code screenshot and output shows that when the string is entered, the output will shows each lettercount irrespective of whether the letter is in capitals or small and does not count non-letter characters (i.e spaces, punctuations etc.)

Which of the following is not an Error Style for data validation?
Brut [27]

Based on the Microsoft Excel data validation, the option that is not an Error Style for data validation is the <em><u>choice that does not show an error alert.</u></em>

Given that there is no option available, the best way to answer this question is to show the types of Error Styles for data validation available.

<h3>Different types of Error Style for data validation</h3>
  • Stop style: this will bring the option of "Retry, " "Cancel, " and "Help."

  • Warning style: this will show "Continue," with options of "Yes," "No," "Cancel," and "Help."

  • Information Style: this will ask you to input the whole number with the option of "Ok," "Cancel," and "Help."

Hence, in this case, it is concluded that the Error Style for data validation is Stop, Warning, and Information Style.
