Write a function in "Racket" that takes as an argument a struct and updates the price field by giving a 30% discount to the original price. For example, given the struct “Jeans” 1223 50 as an argument, the function will update the price field to 35, due to the 30% discount.

In C Write a function named “robot”. This function has twointeger parameters named “forward” and “reverse” anda return of type integer. If the value passed to forward is1 and to reverse is 0 then the return should be 127. Ifthe value passed to forward is 0 and to reverse is 1 thenthe return should be -127. If both are 0 or both havenonzero values, then the return should be 0

In this coding challenge, you will be retrieving email usernames from a string. You will write a function named get_usernames () that takes in a string as it's input parameter, and returns a list of email usernames in the string. The input strings will contain 0 or more emails in the format and the '@' symbol will only appear in the context of an email. The order of usernames should match the order in the input text. username@domainname, For example: EXAMPLE 1 text: "If you need help on an assignment, email help@ucsd.edu or support@gmail.com" return: ['help', 'support'] EXAMPLE 2 text: "Good morning! I hope you're having a great time with CSE 8A!" return: [] EXAMPLE 3 text: "I've been having a lot of trouble reaching you, can you please email me at cse@ucsd.edu? return: ['cse', 'cse'] Here is the problem description: Function Name: get_usernames Parameter: text - A string corresponding to a piece of text containing 0 or more emails. Return: A list of the email usernames in the input…

In C++ Write a function named find_bigfoot which takes a string as an argument, and then determines whether the string "bigfoot" is found in the parameter. Then it returns true or false, depending on whether it was found or not. For example: find_bigfoot("There is no yeti");find_bigfoot("footbig not here"); would both return false, since the string bigfoot isn't part of the string while: find_bigfoot("I believe in bigfoot");find_bigfoot("bigfoot is around here"); would both return true, since the string bigfoot is part of the string.

Write the function data_tuple_from_line(line_str) that takes a line of input (with value separated by commas) and returns a tuple containing install_id, install_date, size, cost, subsidy, zip code, city, state. In the result tuple: The install_id, install_date, zip code, city, and state should all be strings. The size, cost, and subsidy should all be floats. The city should be in title case.

Create a function named fnTuition that calculates the tuition for a student. This function accepts one parameter, the student ID, and it calls the fnStudentUnits function that you created in task 2. The tuition value for the student calculated according to the following pseudocode: if (student does not exist) or (student units = 0)    tuition = 0 else if (student units >= 9)    tuition = (full time cost) + (student units) * (per unit cost) else    tuition = (part time cost) + (student units) * (per unit cost) Retrieve values of FullTimeCost, PartTimeCost, and PerUnitCost from table Tuition. If there is no student with the ID passed to the function, the function should return -1. Code two tests: 1) a student who has < 9 student units, and 2) for a student who has >= 9 student units. For each test, display StudentID and the result returned by the function. Also, run supportive SELECT query or queries that prove the results to be correct.

C++ Write a function named “createPurchaseOrder” that accepts the quantity (integer), the cost per item (double), and the description (string). It will return a newly created PurchaseOrder object holding that information if they are valid: quantity and cost per item cannot be negative and the description cannot be empty or blank(s). When it is invalid, it will return NULL to indicate that it cannot create such PurchaseOrder object.

Using C++ Language In this program you will write a function of void return type named compare that accepts an integer parameter named guess. This function will compare the value of guess with a seeded randomly generated integer between 1 to 100, inclusive, and let the user know what the random number was as well as whether the guess was larger than, smaller than or equal to the random number. NOTE THAT: You will NOT generate a random number inside the compare function. Rather, you will write another function named getRandom of int return type to do it. You will need to call getRandom from compare, no parameters are necessary. Inside your main function, get the guess from user and pass it to the compare function.    Code: #include <iostream>using namespace std; int getRandom(){    //generate seeded random num.    //in between 1-100 inclusive    //return random number } void compare(int guess){    //call getRandom    //compare guess with random number    //inform user what…

This question has 2 parts, in part A you will write a function and part B need to implement the function   Part A - Write a function called getDistance.  This function will have 2 parameters: first is the speed of the object in miles per hour the second is time traveled in hours.  The function will return the distance traveld by multiplying the speed by the time passed by parameter.     Part B will be a small program that will input the speed and time traveled by 2 vehicles.  It will then print which vehicle traveld the furthest and must utilize the function written in part A appropriately.    Complete the starter file below (copy and paste into your answer).     #write your function here   def main():     vehicle1_speed = int(input("Enter the speed of vehicle 1: "))    vehicle1_time = int(input("Enter the time vehicle 1 has traveled: "))       vehicle2_speed = int(input("Enter the speed of vehicle 2: "))    vehicle2_time = int(input("Enter the time vehicle 2 has traveled: "))…
