Answer: The Bios Chip

Explanation:

The Bios chip called Basic Input Output System is a computer's micro processor, a component on the motherboard that helps to start and set up computer system after it is turned on using a Flash memory which is a type of ROM. The essential process of the Bios chip is to ensure the operating system of the computer boots and loads successfully after the system setup process confirming that all the computer drivers devices are in good working conditions.

The conversion of decimal 0.0625 into its binary equivalent. Explain.

Rashid [163]

D. 0.0001.......first the zero before the decimal point is devided by 2....so it gives out 0 as a reminder so u right 0. at first then to do the part after decimal...first multiply 0.625 by 2 which gives out 0.125 as a fractional number so 0 would be the number after "0." ...and again the answer 0.125 is multiplied by 2 which gives out 0.25....so again we get a zero as an integer so now it would be "0.00..." ....again multiply 0.25 by 2 which gives out 0.5....again the integer is 0....so we add another 0 after 0.00....which would then become 0.000.....after that again multiply 0.5 by 2 which would give 1 as a result....as the fractional part is over, u need to stop here....so add that 1 after the 0.000 which gives 0.0001 as a final result.

Write a routine to interchange the mth and nth elements of a singly-linked list. You may assume that the ranks m and n are passe

IRINA_888 [86]

Answer:

//The routine to swap m th and nth ranked elements

void swapmAndn(int m, int n)

{

//Set the linked list head node

Linked_Node **node_head

//To find the m ranked node

//set previous node

Linked_Node *node_prev = NULL;

//set node to store m ranked node as head node

Linked_Node *node_current_m = *node_head;

//set the rank as rm=1

rm =1

//traverse to find the m ranked node

while (node_current_m && rm<m)

{

node_prev = node_current_m;

node_current_m = node_current_m->next;

rm++;

}

//To find the n ranked node

//set previous node

Linked_Node *node_prev_n = NULL;

//set node to store n ranked node as head node

Linked_Node *node_current_n = *node_head;

//set the rank as rn=1

rn =1

//traverse to find the n ranked node

while (node_current_n && rn<n)

{

node_prev_n= node_current_n;

node_current_n = node_current_n->next;

rn++;

}

//if m is not first ranked node

if (node_prev != NULL)

//set node_current_n as previous node

node_prev->next = node_current_n;

//otherwise Set the node_current_n

else

*node_head = node_current_n;

// If n is not first ranked node

if (node_prev_n!= NULL)

node_prev_n->next = node_current_m;

else

*node_head = node_current_m;

//now swap the next pointers also

//to make the swap process complete

Linked_Node *temp = node_current_n->next;

node_current_n->next = node_current_m->next;

node_current_m->next = temp;

}

write the algorithm, flowchart and BASIC program to calculate the area of the rectangle length 50m and width 30m.

GalinKa [24]

Answer:

The Basic Program is as follows:

10 LENGTH = 50

15 WIDTH = 30

20 AREA = WIDTH * LENGTH

25 PRINT AREA

30 END

The Algorithm is as follows:

1. Start

2. Let Length = 50

3. Let Width = 30

4. Compute Area = Length * Width

5. Display Area

6. Stop

See Attachment for flowchart (flowchart is designed using draw io tools)

Explanation:

The flowchart, algorithm and basic program all follow the same sequence and explanation

Using the basic program as a case study;

Line number 10: The program starts by initializing LENGTH to 50

Line number 15: It then initializes WIDTH to 30

Line number 20: The AREA is calculated by LENGTH * WIDTH

Line number 25: The value of AREA is printed afterwards

Line number 30: Lastly, the program stops execution

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.)
