Answer:
because the password being used is of high quality
Explanation:
Option C is the most preferable in terms of system security because the password being used is of high quality. Meaning that it contains lower case and capital case letters as well as numbers. It is also a random mix of all three and is not a common word or name. The length of the password is normal but could be longer for better safety. These things make it very difficult and time-consuming for a software program to guess the password, and nearly impossible for an individual to guess.
Let L be the set of exactly those strings over the alphabet \Sigma = {a, b, c, g}, that satisfy all of the following properties: the length of the string is equal to 5n+3, for some natural number n greater or equal than 0; all of the first (leftmost) 2n symbols are elements of the set {b, c, g}; all of the last (rightmost) 3n symbols are elements of the set {a, b}; the symbols at position 2n+1, 2n+2, and 2n+3 (from the left, i.e., after the first 2n symbols but before the last 3n symbols) are elements of the set {c, g}; Write a complete formal definition of a context free grammar that generates L. If such a context free grammar does not exist, state that the context free grammar does not exist, and prove it.
Answer:
S -> LSR
S -> M
M -> YYY
Y -> c | g
L -> XX
X -> b | c | g
R -> ZZZ
Z -> a | b
Explanation:
This is a long time ago, but I think this does what you want.
Start symbol S expands to LSR and allows you to grow L and R on either side as much as you want. Ultimately S must be replaced by M. Then you have a pattern like LLLLLMRRRRR.
We can then further break down L into 2 times b, c or g, and similar for M and R.

Write code to take a String input from the user, then print the first and last letters of the string on one line. Sample run: Enter a string: surcharge se Hint - we saw in the lesson how to get the first letter of a string using the substring method. Think how you could use the .length() String method to find the index of the last character, and how you could use this index in the substring method to get the last character.
//import the Scanner class to allow for user input
import java.util.Scanner;
//Begin class definition
public class FirstAndLast{
//Begin the main method
public static void main(String []args){
//****create an object of the Scanner class.
//Call the object 'input' to receive user's input
//from the console.
Scanner input = new Scanner(System.in);
//****create a prompt to tell the user what to do.
System.out.println("Enter the string");
//****receive the user's input
//And store it in a String variable called 'str'
String str = input.next();
//****get and print the first character.
//substring(0, 1) - means get all the characters starting
//from the lower bound (index 0) up to, but not including the upper
//bound(index 1).
//That technically means the first character.
System.out.print(str.substring(0,1));
//****get and print the last character
//1. str.length() will return the number of character in the string 'str'.
//This is also the length of the string
//2. substring(str.length() - 1) - means get all the characters starting

Explanation:
The variable options is a list containing 5 string values
options = ["ski", "surf", "jog", "bike", "hike"]
Indexing in python starts from 0 ; hence the index values of the list values are :
0 - ski
1 - surf
2 - jog
3 - bike
4 - hike
The statement ;
print(options[2]) means print the string at index 2 in the list named options
The string at index 2 is jog ;
Hence, the string jog is printed.

Explanation:
In this lab, you complete a C++ program that uses an array to store data for the village of Marengo.
The program is described in Chapter 8, Exercise 5, in Programming Logic and Design. The program should allow the user to enter each household size and determine the mean and median household size in Marengo. The program should output the mean and median household size in Marengo. The file provided for this lab contains the necessary variable declarations and input statements. You need to write the code that sorts the household sizes in ascending order using a bubble sort and then prints the mean and median household size in Marengo. Comments in the code tell you where to write your statements.
Instructions
Make sure that the file HouseholdSize.cpp is selected and open.
Write the bubble sort.
Output the mean and median household size in Marengo.
Execute the program by clicking the Run button and the bottom of the screen.
Enter the following input, and ensure the output is correct. Household sizes: 4, 1, 2, 4, 3, 3, 2, 2, 2, 4, 5, 6 followed by 999 to exit the program.
Here is my code so far. I need help finishing it (printing the mean & median, etc). Thanks so much:
// HouseholdSize.cpp - This program uses a bubble sort to arrange up to 300 household sizes in
// descending order and then prints the mean and median household size.
// Input: Interactive.
// Output: Mean and median household size.
#include
#include
using namespace std;
int main()
{
// Declare variables.
const int SIZE = 300; // Number of household sizes
int householdSizes[SIZE]; // Array used to store 300 household sizes
int x;
int limit = SIZE;
int householdSize = 0;
int pairsToCompare;
bool switchOccurred;
int temp;
double sum = 0;
double mean = 0;
double median = 0;
// Input household size
cout << "Enter household size or 999 to quit: ";
cin >> householdSize;
// This is the work done in the fillArray() function
x = 0;
while(x < limit && householdSize != 999)
{
// Place value in array.
householdSizes[x] = householdSize;
// Calculate total of household sizes
sum+= householdSizes[x];
x++; // Get ready for next input item.
cout << "Enter household size or 999 to quit: ";
cin >> householdSize;
} // End of input loop.
limit = x;
// Find the mean
// This is the work done in the sortArray() function
pairsToCompare = limit - 1;
switchOccured = true;
while(switchOccured == true)
{
x = 0;
switchOccured == false;
while (x < pairsToCompare)
{
if(householdSizes[x]) > householdSizes[x+1])
{
//perform switch
}
x++;
}
pairsToCompare--;
}
// This is the work done in the displayArray() function
//Print the mean
// Find the median
median = (limit-1) / 2;
if (limit % 2 ==0)
{
cout << "Median is: " << (householdSizes[(int)median] + householdSizes[(int)median + 1]) / 2.0 << endl;
}
else {
// Print the median household size
}
// Print the median
return 0;
} // End of main function
Answer:
For the mean, do the following:
mean = sum/limit;
cout<<"Mean: "<<mean;
For the median do the following:
for(int i = 0; i<limit; i++) {
for(int j = i+1; j<limit; j++){
if(householdSizes[j] < householdSizes[i]){
temp = householdSizes[i];
householdSizes[i] = householdSizes[j];
householdSizes[j] = temp; } } }
median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;
if((limit - 1)%2==0){
median = householdSizes[limit/2];
}
cout<<endl<<"Median: "<<median;
Explanation:
The bubble sort algorithm in your program is not well implemented;
So, I replaced the one in your program with another.
Also, some variable declarations were removed (as they were no longer needed) --- See attachment for complete program
Calculate mean
mean = sum/limit;
Print mean
cout<<"Mean: "<<mean;
Iterate through each element
for(int i = 0; i<limit; i++) {
Iterate through every other elements forward
for(int j = i+1; j<limit; j++){
Compare both elements
if(householdSizes[j] < householdSizes[i]){
Reposition the elements if not properly sorted
temp = householdSizes[i];
householdSizes[i] = householdSizes[j];
householdSizes[j] = temp; } } }
Calculate the median for even elements
median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;
Calculate the median for odd elements
if((limit - 1)%2==0){
median = householdSizes[limit/2];
}
Print median
cout<<endl<<"Median: "<<median;
write a program to display your name, age and address in c programming
Answer:
The program in C is as follows:
#include <stdio.h>
int main(){
char name[] = "Mr. Royal";
int age = 20;
char address[] = "Lagos, Nigeria";
printf("Your name is %s.\n", name);
printf("You are %d years old\n", age);
printf("Your address is %s.", address);
return 0;
}
Explanation:
This initializes the name
char name[] = "Mr. Royal";
This initializes the age
int age = 20;
This initializes the address
char address[] = "Lagos, Nigeria";
This prints the name
printf("Your name is %s.\n", name);
This prints the age
printf("You are %d years old\n", age);
This prints the address
printf("Your address is %s.", address);
