Answer:

def check_password(password):

is_short = False

has_uppercase = False

has_lowercase = False

has_digit = False

if len(password) < 8:

is_short = True

for p in password:

if p.isupper():

has_uppercase = True

if p.islower():

has_lowercase = True

if p.isdigit():

has_digit = True

if is_short == False and has_uppercase and has_uppercase and has_digit:

return True

else:

return False

while True:

password = input("Enter your password: ")

password2 = input("Enter your password again: ")

if password == password2 and check_password(password):

break

Explanation:

Create a function named check_password that takes one parameter, password

Inside the function:

Initialize the is_short, has_uppercase, has_lowercase, and has_digit as False. These variables will be used to check each situation

Check the length of the password using len() method. If it is smaller than 8, set is_short as True

Create a for loop that iterates through password. Check each character. If a character is uppercase, set the has_uppercase as True (use isupper() function). If a character is lowercase, set the has_lowercase as True (use islower() function). If a character is a digit, set the has_digit as True (use isdigit() function).

When the loop is done, check the value of is_short, has_uppercase, has_lowercase, and has_digit. If is_short is False and other values are True, return True. Otherwise, return False

Create an indefinite while loop, that asks the user to enter password twice. Check the entered passwords. If they are equal and the check_password function returns True, stop the loop. This implies that both passwords are same and password is valid.

Here is the Python program along with the comments of program design

#this program is designed to compute the average quiz grades for a group of five students

students = ["Alex", "John", "David", "Joseph", "Mathew"] #create a list of 5 students

grades = [] # create an empty list to store the grades in

for student in students: #loop through the students list

grade = input("Enter the quiz grade for "+student+": ") #prompt the user for the quiz grade of each student

#store the input grades of each student to grade

grades.append(int(grade)) # convert the grade to an integer number and append it to the list

print("Grades are:", grades) #display the grades of five students

average = sum(grades) / len(grades) #compute the average of five grades

print("The average of grades is:", average) #display the average of five grades

highest = max(grades) #compute the highest grade

print("The highest grade is:", highest) #print highest grade

Explanation:

The program first creates a list of 5 students who are:

Alex

John

David

Joseph

Mathew

It stores these into a list named students.

Next the program creates another list named grades to store the grades of each of the above students.

Next the program prompts the user for the quiz grade for each of the five students and accepts input grades using input() method. The statement contains student variable so each prompt includes the name of the student whose quiz grade is to be input. Each of the grades are stored in grade variable.

Next the append() method is used to add each of the input grades stored in grade to the list grades. The int() method is used to first convert these grades into integer.

Next print() method is used to display the list grades on output screen which contains grades of 5 students.

Next the average is computed by taking the sum of all input grades and dividing the sum by the total number of grades. The sum() method is used to compute the sum and len() method is used to return the number of grades i.e. 5. The result is stored in average. Then the print() method is used to display the resultant value of average.

At last the highest of the grades is computed by using max() method which returns the maximum value from the grades list and print() method is used to display the highest value.

Answer:

18

Explanation:

If you take the formula, and you substitute the values of the variables, it will be:

10 * 2 - 10 / 5

Then if you remember the order of math operations, it will be:

(10 * 2) - (10 / 5)

Which reduces to:

20 - 2 = 18

The value of the variable result is 18

The code is represented as follows:

Python code:

a = 10

b = 2

c = 5

result = a * b - a / c

Code explanation;The variable a is initialise to 10The variable b is initialise to 2Lastly, the variable c is initialise to 5

Then the arithmetic operation variable a multiplied by variable b minus variable a divided by variable c is stored in the variable "result".

Printing the variable "result" will give you 18.

Here is the JAVA program:

import java.util.Scanner; //to accept input from user

public class Main{ //class name

public static void main(String[] args){//start of main function

String sentence; //to store the input sentence

int i, length; //declare variables

int count[] = new int[256]; //creates a counter array

Scanner input = new Scanner(System.in); //creates Scanner class object to accept input from user

System.out.println("Enter a sentence: "); //prompts user to enter a sentence

sentence = input.nextLine(); //scans and reads the entire sentence string from user

String[] words = sentence.split("\\s+"); //splits the sentence into an array with separator as one or more white spaces and stores this array in words

System.out.println("Number of words: " + words.length); //display the number of words in sentence by using length which returns the length of the words array

sentence = sentence.toLowerCase(); // converts the sentence into lower case to ignore case sensitivity

sentence = sentence.replaceAll("\\s+",""); //removes the empty spaces from sentence

length = sentence.length(); //stores the length of the sentence string into length variable

for (i = 0; i < length; i++) { //iterates through the length of the sentence

count[(int) sentence.charAt(i)]++; } //counts occurrence of each alphabet in the sentence and stores it in count array

for (i = 0; i < 256; i++) { displays occurrence of alphabet in sentence

if (count[i] != 0) { //if count array is not empty

System.out.println((char) i + "-" + count[i]); }}}}

//prints each alphabet and its count

Explanation:

The program prompts the user to enter a sentence. Suppose the user enters "We won" so

sentence = "We won"

Now this sentence splits into an array with white space as separator and stored in words array. So words array has two words of sentence now i.e. "We" and "won"

Next words.length is used to return the length of words array. So length of words array is 2 hence

number of words = 2

Next the sentence is converted to lower case and spaces are removes so sentence becomes:

wewon

sentence.length() returns the length of sentence which is 5.

Next the for loop is used. At each iteration of this loop occurrence each character of sentence is added to the count[] array. charAt() is used to return a character at each index position of string. So the frequency of every character is counted and stored in count array.

Next is a for loop that is used to display each alphabet in the sentence along with its frequency in alphabetic order.

Hence the entire program gives the output:

Number of words: 2 e-1 n-1 o-1 w-2

Answer: B I took the test

Explanation:

The function that will add a name to a list of baseball players in Python is main(). The correct option is b.

What is python?

Python is a popular computer programming language used to create software and websites, automate processes, and analyze data. Python is a general-purpose language, which means it may be used to make many various types of applications and isn't tailored for any particular issues.

A function is a section of code that only executes when called. You can supply parameters—data—to a function. The main() function in Python serves as the point at which any software application is executed.

Since the program only runs when it is executed directly, and not if it is imported as a module, the execution of the program can only begin when the main() function is declared in Python.

Therefore, the correct option is b, main().

Explanation:

When it comes to collecting information such as the user's name, telephone number, address, etc., it is important to insert a text box into the form field. This can be done in several ways, such as giving the user the freedom to type her own response in the text box or making it "pre-filled." A text box with pre-filled value means that the user cannot type anything in the box because it has an existing value (default value). The text box may also give a "hint" in order to let the user know of possible values he can choose.

Explanation:

The answers are straight forward.

However, I'll give a general hint in answering questions like this.

In C, variable declaration is done by:

data-type variable-name;

To declare and initialise the variable, you do;

data-type variable-name = value;

So, for questions that requires that we declare and initialise a variable, we make use of the above syntax..

Take (a) for instance:

int x = 25;

int y = 18;

Same syntax can be applied to (b), (d), (e), (h) & (I)

For question (c);

This can be done in two ways;

x = x + 5;

Or

x+=5;

Both will give the same result.

For question (f):

We start by initialise a temporary variable that stores x.

Then we store the value of x in y.

Then we store the content of the temporary variable to y.

This swaps the values of x and y

For question (g):

When printing a double variable in C, we make use of '\f' as a string format

For question (j):

Explanation:

[tex]\blue{ central ~proccecing ~unit }[/tex] ⠀

Answer:

Here is the C++ program:

#include <iostream> //to use input output functions

using namespace std; //to identify objects cin cout

int main(){ //start of main method

double risingLevel; //declares a double type variable to hold rising level

cin>>risingLevel; //reads the value of risingLevel from user

cout<<"Level: "<<risingLevel<<endl; //displays the rising level

cout << "Years: 5, Rise: " << risingLevel * 5<<endl; //displays the rise in ocean level over 5 years

cout << "Years: 10, Rise: " << risingLevel * 10<<endl; //displays the rise in ocean level over 10 years

cout << "Years: 50, Rise: " << risingLevel * 50<<endl; //displays the rise in ocean level over 50 years

}

Explanation:

The program works as follows:

Lets say the user enters rising level 2.1 then,

risingLevel = 2.1

Now the first print (cout) statement :

cout<<"Level: "<<risingLevel<<endl; prints the value of risingLevel on output screen. So this statement displays:

Level: 2.1

Next, the program control moves to the statement:

cout << "Years: 5, Rise: " << risingLevel * 5<<endl;

which computes the rise in ocean levels over 5 years by formula:

risingLevel * 5 = 2.1 * 5 = 10.5

It then displays the computed value on output screen. So this statement displays:

Years: 5, Rise: 10.5 Next, the program control moves to the statement:

cout << "Years: 10, Rise: " << risingLevel * 10<<endl;

which computes the rise in ocean levels over 10 years by formula:

risingLevel * 10 = 2.1 * 10 = 21

It then displays the computed value on output screen. So this statement displays:

Years: 10, Rise: 21

Next, the program control moves to the statement:

cout << "Years: 50, Rise: " << risingLevel * 50<<endl;

which computes the rise in ocean levels over 50 years by formula:

risingLevel * 50 = 2.1 * 50 = 105

It then displays the computed value on output screen. So this statement displays:

Years: 50, Rise: 105 Hence the output of the entire program is:

Level: 2.1 Years: 5, Rise: 10.5 Years: 10, Rise: 21 Years: 50, Rise: 105
