I am trying to make a robot move (theoretically), some of my code does not work in python. I am getting some errors. How can I fix it?

This is my code:

#!/usr/bin/env python.3

import time
import sys
import random

#Provide a Menu for the User
def main():
print("To control LED press 1")
print("To drive press 2")
print("To change motor speed press 3")
print("To control the Servo press 4")
while True:
option = int(input("Enter the numbers 1, 2, 3, or 4:"))
if option == 1:

else:
print("Wrong letter or number, please try again.")

print("To exit press 0")
while True:
option = int(input("Enter numbers 5 or 6:"))
if option == 5:
led_on(0)

  
elif option == 6:

Write the code of:
– an abstract class called Creature
– classes Player and Monster (derived from Creature)
– classes WildPig and Dragon (derived from Monster)

In the Creature class
– Define a string member, Creature Name, to store the class Creature’s name.(name should be dynamically allocated)
– Define Two virtual pure functions

• void DoAction() : Print the action of the object, and the actions have to be different from different classes.

• void DrawOnScreen() : Print the object’s name and call DoAction() belonging to the same class.
The class definition of Creature is:


Question: Implement the class Player, Monster, Dragon and Wildpig so that when execution the following code, the counsel shows the execution result as the following:

Counsel output:

Player <Kick_Ass> is attacking!!
Monster<UFO> is doing monster stuff!!
WildPig <I'm_Hungry> is Running!!
Dragon<I'm_the_Boss> is breathing Fire!!

Main function:
//==================================================
int main(){
Player hero("Kick_Ass");
Monster mon("UFO");
WildPig pig("I'm_Hungry");
Dragon drag("I'm_the_Boss");
Creature* object[4];
object[0]=&hero;
object[1]=&mon;
object[2]=&pig;
object[3]=&drag;
object[0]->DrawOnScreen();
object[1]->DrawOnScreen();
object[2]->DrawOnScreen();
object[3]->DrawOnScreen();

return0;
}
c++

Create program in Python (using import turtle):

1)includes draw_background function

2)draw_background function uses a loop to draw a background from at least one shape

3)uses at least 2 turtles to draw scent

4)includes draw_shape function

5)includes function to draw primary object

6)includes main method which creates the drawing

How do you translate this pseudocode to regular code in C++?

for i :1 to length(A) - 1

j = i

while j > 0 and A[j - 1] > A[j]

swap A[j] and A[j - 1]

j = j -1

The following functions have zero or more security issues given the way they are called in the main() function. Identity these security issues and propose a compliant fix. You don’t need to consider the issues in the main() function.

1. setValue set the element at index in arr to value.

void setValue ( int * arr , int len , int value , int index ) {

                arr [ index ] = value ;

}

int main ( void ) {

                int arr [10];

                int value ;

                int index ;

                printf (" Enter the value :\ n ");

                scanf ("% d " , & value );

                printf (" Enter the position :\ n ");

                scanf ("% d " , & index );

                setValue ( arr , 10 , value , index );

                return 0;

}

2. createArray creates an int array of size len. It, then, initializes each element in the array with value.

int * createArray ( int len , int value ) {

                int * arr = ( int *) malloc ( sizeof ( int ) * len );

                memset ( arr , value , sizeof ( int ) * len );

                return arr ;

                }

int main ( void ) {

                int value ;

                int len ;

                printf (" Enter the value :\ n ");

                scanf ("% d " , & value );

                printf (" Enter the length :\ n ");

                scanf ("% d " , & len );

                int * arr = createArray ( len , value );

                if ( arr != NULL ) {

                                if ( len > 0) {

                                printf (" The first element is % d \ n " , arr [0]);

                                }

                free ( arr );

                }

return 0;

}

3. writeToFile asks the user to input a string and then write the entered string to “out.txt”.

void writeToFile () {

                char buffer [20];

                printf (" Enter the content :\ n ");

                scanf ("% s " , buffer );

                FILE * f = fopen (" out . txt " , " w ");

                fputs ( buffer );

                fclose ( f );

                }

int main ( void ) {

                writeToFile ();

                return 0;

}

4. sum returns the sum of two integers.

long long sum ( int a , int b ) {

                return a + b ;

                }

int main ( void ) {

                int a = 0;

                int b = 0;

                printf (" Enter a :\ n ");

                scanf ("% d " , & a );

                printf (" Enter b :\ n ");

                scanf ("% d " , & b );

                printf (" sum of a and b is % ld \ n " , sum (a , b ));

                return 0;

}

5. swap swaps the integer value stored in a and b.

void swap ( int * a , int * b ) {

                * a += * b ;

                * b = * a - * b ;

                * a = * a - * b ;

                }

int main ( void ) {

                int a = 0;

                int b = 0;

                printf (" Enter a :\ n ");

                scanf ("% d " , & a );

                printf (" Enter b :\ n ");

                scanf ("% d " , & b );

                swap (& a , & b );

                printf (" a is %d , b is % d \ n " , a , b );

                return 0;

}

Please use c# and write a console application

Part 1) A small airline has just purchased a computer for its newly automated reservations system. You have been asked to develop a new system. You are to write an application to assign seats on each flight of the airline’s only plane. The plane has ten rows and each row has 2 seats (total capacity: 20 seats). The first five rows are for first class passengers, while the remaining rows are for economy passengers. The application is used by an airline employee who is given the task of assigning all seats to passengers (one passenger at a time). Your application should display the following alternatives: Please type 1 for First Class and Please type 2 for Economy or type 3 to see the status of all seats. If the user types 1, your application should assign a seat in the first-class section (rows 1–5). If the user types 2, your application should assign a seat in the economy section (rows 6–10).
If the user types 3, the application will display the status of all seats (“A” for available and “X” for booked) as shown below. The application will continue to ask for the user’s input until the flight is full or the user suggests that they do not want to assign anymore seats.
Availability Status:
X   X
X   X
X   A
A   A
A   A

X   X
X   X
X   X
X   X
A   A

Your application should never assign a seat that has already been assigned. When the economy section is full, your application should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message "Next flight leaves in 3 hours." You will need to use a multi-dimensional array to solve this problem. 

Part 2) Use a one-dimensional array to solve the following problem: A company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9% of $5000, or a total of $650. Write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson’s salary is truncated to an integer amount):
a) $200–299
b) $300–399
c) $400–499
d) $500–599
e) $600–699
f) $700–799
g) $800–899
h) $900–999
i) $1000 and over
The application will accept sales amount until the user enters -1 to end (as shown in figure 2.1 below). At this point, the application calculates the salary and updates the appropriate counter of the array. For instance, if the salesperson gets a total salary of $565, you will update the counter that is counting totals between the $500-$599 range.

Figure 2.1. Receiving input from user

Note that you do NOT need to store the individual salary of the salesperson. Summarize the results in tabular format Use only a for loop to display the output.

Final output showing all ranges and the number of agents that received commission in that range

3. Describe the divide-and-conquer search algorithm and explain its efficiency. Consider two different Split functions: Split = Lo, and Split = (Lo + Hi) / 2. Draw the trees of recursive calls. Assume that we are searching a large data base with 4 million items represented as an ordered array. How many probes into the list will the binary search require before finding the target or concluding that it cannot be found? Assume that it takes 1 microsecond to access an item, estimate the execution time of the binary search.

You have been approached by the Statistics Canada to create a C# program to calculate the average salary of people with university degrees, college diplomas, and high school diplomas. Using a while loop, you are to process salary data until the user indicates that you should stop (there could be 0 or more data values). For each person processed, the program must first input an education type (char edType) (‘U’ or ‘u’ for university degrees, ‘C’ or ‘c’ for college diplomas, and ‘H’ or ‘h’ for high school) and then a salary (double salaryData). The program stops accepting input when the user enters a ‘Q’ or ‘q’ for quit (use a sentinel value while loop). Your main data processing loop should be conditioned on the fact that the user has not signalled quit. It might look something like:

while(char.ToUpper(edType) != ‘Q’)

This implies that like any sentinel value loop, you must seed the loop (input a value) PRIOR to entering the loop. Inside the loop the salary data is entered and processed. Once the main loop terminates, the average salary for each of the three education types should be printed out. Be sure to print an error message if the user enters an invalid education type or a negative salary.
