When a cache block has been modified since being read from main memory <span>the dirty bit is set.
in computer terms, dirty bit is a corresponding block of memory which stays within the memory system after the processor is done to modify this memory. Cache blocking is one of the processes needed for the modification.</span>

Write two alternate functions specified below, each of which simply triples the variable count defined in main. These two functi

Vedmedyk [2.9K]

Answer:

Following are the code to this question:

#include <iostream>//header file

using namespace std;

int triplebyValue(int count)//defining a method triplebyValue

{

int x=count*3;//defining a variable x that multiply by 3 in the count

return x;//return value of x

}

void triplebyReference(int& count)//defining a method triplebyReference that hold count variable as a reference in parameter

{

count*=3;//multipling a value 3 in the count variable

}

int main()//main method

{

int count;//defining integer variable

count=triplebyValue(3);//use count to call triplebyValue method

cout<<"After call by value, count= "<<count<<endl;//print count value with message

triplebyReference(count);//calling a method triplebyReference

cout<<"After call by reference, count= "<<count<<endl;//print count value with message

return 0;

}

Output:

After call by value, count= 9

After call by reference, count= 27

Explanation:

In this code two methods "triplebyValue and triplebyReference" are declared, which accepts a count variable as a parameter, and in both multiply the count value by 3 and return its value.

Inside the main method, an integer variable "count" is declared that first calls the "triplebyValue" method and holds its value into count variable and in the next, the method value is a pass in another method that is "triplebyReference", and use print method to print both methods value with a message.

Write a program palindrome.py that prompts for a sequence of words or numbers on a single line and checks if the entries are pal

olya-2409 [2.1K]

Answer:

Explanation:

The program first asks the user for the sequence of words. Then it splits the sequence into an array of words. Then it loops through the array checking each word to see if it is a palindrome. If it is it prints the word, the boolean value, and adds 1 to the palindrome_count variable. Otherwise it prints the word, false, and moves on to the next word in the list. Finally, it prints out the total value of palindrome_count.

word = input("Enter sequence of words: ")

word_list = word.split(' ')

print(word_list)

palindrome_count = 0

for word in word_list:

print('\n\n')

reverse = word[::-1]

if word == reverse:

print(word, end='\n')

print(True, end="\n")

palindrome_count += 1

else:

print(word, end='\n')

print(False, end='\n')

print("\n\nNumber of Palindromes in Sequence: " + str(palindrome_count))

Solution :

Digital recording may be defined as the preservation of an audio or some visual signals like the series of a binary numbers which can be stored on a magnetic tape or on an optical disc or some other digital storage media.

Some of the best practices for doing digital recording are :

1. We should always take permission from those who are being recorded. It is not right to shoot others without their permission. It is against the right to privacy.

2. We should record audio at about 44.1 kHz/16 bit in an uncompressed wave format.

3. A High quality MP3 (192 kbps or higher) is often accepted due to the limitations of a recorder or for a storage space.

The MP3 recordings are considered as the best option for certain recorders and when the storage space is severely limited. It produces a good quality recording.
