Answer:

256.

Explanation:

In Computer science, a bit is a short word for the term binary digit and is primarily the basic (smallest) unit measurement of data or information.

A bit is a logical state which represents a single binary value of either one (1) or zero (0). This ultimately implies that, a single bit in computer science represents a boolean value of;

1. True or ON, which is equal to one (1).

2. False or OFF, which is equal to zero (0).

Additionally, a binary numbering represents all numeric values that are to be written in sequences of ones (1s) and zeroes (0s). Therefore, a binary number refers to any numerical value (number) that is expressed in base-2 numerical system; 0s and 1s.

Also, the total numbers which can be represented with an 8 bit binary (base-2) system is 256.

Mathematically, it is given by the equation;

$2^{n}$

Given that n = 8

$2^{8} = 256$

Answer:

Explanation:

#include <iostream>

using namespace std;

int main ()

{

int responses[30],count[6];

int score = 0;

string resp = " ";

for (int i = 0; i < 30; i++)

{

responses[i] = 0;

}

for (int i = 0; i < 6; i++)

{

count[i,1]=0;

count[i,2]=0;

count[i,0]=0;

}

while ((resp != "Y") && (resp != "y"))

{

for (int i = 0; i < 30; i++)

{

while ((score > 5) || (score < 1))

{

cout << "Student " << (i+1)<< " please enter a value (1-5):";

cin >> score;

}

responses[i] = score;

if((score > 5)||(score<1))

{

if(score==1) count[1]++;

if(score==2) count[2]++;

if(score==3) count[3]++;

if(score==4) count[4]++;

if(score==5) count[5]++;

}

score = 0;

}

cout<< "Response Frequency Percentage"<<endl;;

cout<< " 1 "<<count[1]<<" "<<(count[1]/30)<<"%"<<endl;

cout<< " 2 "<<count[2]<<" "<<(count[2]/30)<<"%"<<endl;

cout<< " 3 "<<count[3]<<" "<<(count[3]/30)<<"%"<<endl;

cout<< " 4 "<<count[4]<<" "<<(count[4]/30)<<"%"<<endl;

cout<< " 5 "<<count[5]<<" "<<(count[5]/30)<<"%"<<endl;

cout<< "Do you want to exit? Press Y to exit any other key to continue: ";

cin>> resp;

}

return 0;

In this exercise, your function will receive 2 parameters, the name of a text file, and a list of strings. The function will wri

diamong [38]

Answer:

# the function is defined

# it takes 2 arguments: filename and list of string

def solution(filename, listOfString):

# the file is opened in write mode

# so that we can write to it

with open(filename, 'w') as file_object:

# we loop through the entire list of string

# this looping help us know what to write to the file

for each_string in listOfString:

# if the length of the string is less than 4

# we write 'x' with a new line

if len(each_string) < 4:

file_object.write("x\n")

# else if the length of the string is greater than equals 4

# we write the fourth character

# and also add new line

else:

file_object.write(each_string[3])

file_object.write("\n")

Explanation:

The function is written in Python. It takes two argument; filename and list of string.

It opens the file in write mode and then loop through the list of string. During the loop, we know what to write to the file.

In the length of a string is less than 4; we write 'x' else we write the fourth character in the string. The fourth character has an index of 3 because string uses zero index counting like a string. Starting from zero; 0, 1, 2, 3, 4... the fourth character has an index of 3.
