The codehs 7.4.4 program is meant to return the square of a number

<h3>How to write the actual program</h3>

The program in Python, where comments are used to explain each line is as follows:

#This gets input for the number

userNum = int(input("Number: "))

#This prints the square of the number

print(userNum**2)

Monster Collector
Lera25 [3.4K]

Answer:

In java:

import java.util.*;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int monsternum, usernum;

 int count = 0;

 Random rand = new Random();

 String [] monsters = {"wild pikamoo","wild bulbaroar"};

 for(int i =0;i<2;i++){

     monsternum = rand.nextInt(5);  

     System.out.print("A "+monsters[i]+" appears! Guess a number between 1 and 5: ");

     usernum = input.nextInt();

     if(monsternum == usernum){      count++;      System.out.println("Congratulations, you caught a "+monsters[i]+"!");  }

 else{      System.out.println("You almost had it, but the monster escaped.");  }

 

 }

 System.out.println("There are no more monsters to encounter!");

 System.out.println("You caught "+count+" monsters of 2");

 if(count!=2){      System.out.print("Keep training to be the very best!");  }

 else{      System.out.print("You're the monster collector master!");  }

}

}

Explanation:

This declares monster and user number as integers

 int monsternum, usernum;

Initialize count to 0

 int count = 0;

Call the random object

 Random rand = new Random();

Create a string array to save the monster names

 String [] monsters = {"wild pikamoo","wild bulbaroar"};

Iterate for the 2 monsters

 for(int i =0;i<2;i++){

Generate a monster number

     monsternum = rand.nextInt(5);  

Prompt the user to take a guess

     System.out.print("A "+monsters[i]+" appears! Guess a number between 1 and 5: ");

Get user guess

     usernum = input.nextInt();

If monster number and user guess are equal, congratulate the user and increase count by 1

<em>      if(monsternum == usernum){      count++;      System.out.println("Congratulations, you caught a "+monsters[i]+"!");  } </em>

If otherwise, prompt the user to keep trying

<em>  else{      System.out.println("You almost had it, but the monster escaped.");  }  </em>

<em>  } </em>

Print no monsters again

 System.out.println("There are no more monsters to encounter!");

Print number of monsters caught

 System.out.println("You caught "+count+" monsters of 2");

Print user score

<em>  if(count!=2){      System.out.print("Keep training to be the very best!");  } </em>

<em>  else{      System.out.print("You're the monster collector master!");  } </em>

How to write a program converting RGB to CMYK in python
Arisa [49]

rgb_scale = 255

cmyk_scale = 100

def rgb_to_cmyk(r,g,b):

if (r == 0) and (g == 0) and (b == 0):

return 0, 0, 0, cmyk_scale

# rgb [0,255] -> cmy [0,1]

c = 1 - r / float(rgb_scale)

m = 1 - g / float(rgb_scale)

y = 1 - b / float(rgb_scale)

min_cmy = min(c, m, y)

c = (c - min_cmy)

m = (m - min_cmy)

y = (y - min_cmy)

k = min_cmy

return c*cmyk_scale, m*cmyk_scale, y*cmyk_scale, k*cmyk_scale

def cmyk_to_rgb(c,m,y,k):

r = rgb_scale*(1.0-(c+k)/float(cmyk_scale))

g = rgb_scale*(1.0-(m+k)/float(cmyk_scale))

b = rgb_scale*(1.0-(y+k)/float(cmyk_scale))

return r,g,b

Assure that major, minor, sub1 and sub2 each contain four digit numbersIf less than four digits are entered in major OR minor OR
Zigmanuir [339]

Answer:

import re

#section 1

while True:

   try:

       major=input('Enter Major: ')

       if re.search(r'^\d{1,4}$',major):

           minor=input('Enter minor: ')

       else:

           raise

       try:

           if re.search(r'^\d{1,4}$',minor):

               sub1=input('Enter sub1: ')

           else:

               raise

       

           try:

               if re.search(r'^\d{1,4}$',sub1):

                   sub2=input('Enter sub2: ')

               else:

                   raise

           

               try:

                   if re.search(r'^\d{1,4}$',sub2):

                       break

                   else:

                       raise

               except:

                   print('enter a correct sub 2')

           except:

               print('enter a correct sub1')        

       except:

           print('Enter a correct minor ')            

   except:

        print('enter a correct Major')

#section 2

sub1= f"{int(sub1):04d}"

sub2= f"{int(sub2):04d}"

major= f"{int(major):04d}"

minor= f"{int(minor):04d}"

if major == '0000' and minor == '0000' and sub1=='0000' and sub2=='0000':

   print('INVALID!!! Acount Number')

else:

   print('-----------------------')

   print('Your Account Number is')

   print(major, minor, sub1, sub2)

   print('-----------------------')

Explanation:

The programming language used is python 3

The Regular  Expression Module was imported to allow us perform special operations on string variables.

This is the pattern that was used to check if an input was valid or invalid re.search(r'^\d{1,4}$',string)

what this pattern does is that it ensures that:

  1. (\d) represents digits that is any number from 0-9.
  2. ( ^ ) ensures that it starts with a digit.
  3. ({1,4}) accepts digits with length ranging from 1-4. i.e you can enter at least one digit and at most four digits.
  4. ($) ensures that the input ends with a digit
  5. string is the text that is passed to the pattern

we also made use of fstrings

sub1= f"{int(sub1):04d}"

the above line of code takes 'sub1' in this case, and converts it temporarily to an integer and ensures it has a length of 4 by adding 0's in front of it to convert it to a four digit number.

These are the major though areas, but i'll explain the sections too.

#section 1

In this section the WHILE loop is used in conjunction with the TRY and EXCEPT block and the IF statement to ensure that the correct input is given.

The while loop will keep looping until the correct input is inserted  before it breaks and each input is tested in the try and except block using the if statement and the regular expression pattern I explained, as a result, you cannot input a letter, a blank space, a punctuation or numbers with length greater than 4, it has to be numbers within the range of 1-4.

#section 2

The second section converts each entry to a four digit number and checks with an if statement if the entry is all zeros (0000 0000 0000 0000) and prints invalid.

Otherwise, it prints the account number.

check the attachment to see how the script runs.
