write a function get_intersecting_station(line_one, line_two) where line_one and line_two are the colors of the lines. This function should return the name of the station where the two lines intersect. Recall from our simplification, there will be only one. If there is no intersecting station, return None use python
In RStudio the following code will return 3 2 when I use the dim function. Can someone explain to me step-bystep how RStudio gets to the following result? dfch <- data.frame( "City" = c("St.Gallen", "Lausanne", "Zürich" ), "PartyLeft" = c(35, 45, 55), "PartyRight" = c(40, 35, 30)) dim(dfch[ , dfch$PartyLeft > 40] Also when we use dfch[ , dfch$PartyLeft > 40 ] returns a 3x2 matrix with column PartyLeft and PartyRight. How does RStudio proceed to get to that answer?
library contains books, periodicals, and DVDs (no items of other types are available and a given item belongs to only a single category). All these items can be used by the user of the library. Some of the items (books, periodicals, and DVDs) are only reference items, and others can be borrowed by the users. There are two types of users; registered users and temporary users. While registered users can borrow up to 100 items, the temporary users can borrow only 2 items at a time. In the initial work of the EER modeling, your teammates have identified Item, User, and ItemCopy as entities. Which of the following statements are correct about a possible EER model for this set of requirements? The specialization/generalization hierarchy for items that involve borrowing items and reference items has an optional participation constraint. The specialization/generalization hierarchy for items that involve the books, periodicals, and DVDs has a mandatory participation constraint. The user…
This is my main.cpp, if there's anything wrong with it in relation to the assignment, please point it out and how to solve it. I can't get my functions.cpp to connect properly to the main.cpp. I need the functions.cpp first, anything else comes second. Thank you very much. main.cpp: #include <iostream> #include <fstream> #include <iomanip> #include <string> #include "functions.cpp" using namespace std; //struct for menuItemType struct menuItemType { string menuItem; double menuPrice; } void getData(menuItemType menuList[]); void showMenu(menuItemType menuList[], int x); void printCheck(menuItemType menuList[], int menuOrder[], int x); int main(); { // Declare functions and variables const int menuItems = 8; menuItemType menuList[menuItems]; int menuOrder[menuItems] = {0}; int orderChoice = 0; bool ordering = true; int count = 0; // Set the menu getData(menuList);…
Please complete the following function getGrade, which accepts only one parameter (int score), and must return its proper grade (i.e., char grade) to the caller.

Thank you! grade = 'A' if score == 4 ; grade = 'B' if score == 3 ; grade = 'C' if score == 2 ; grade = 'D' if score == 1 ; grade = 'F' if score == 0 ; Otherwise, grade = '?' ; char getGrade( int score) // function returns a char to the caller { // parameter 1: int score (4 for example) // return: char grade (‘A’ for example) char grade = '?' ; // This is the only variable you can use ********* NEED HELP HERE ********* return grade ; } // end char getGrade( ) void main() // To test function getGrade( ) { cout << "score 4 -> grade = "…
Write a function named join_words() that does not take any input parameter. It repeatedly asks the user to enter words until they enter a period ("."). Your function should then print all of the words they entered (including the period) on a single line separated by spaces. This function does not return any output. Call the function to test the output. For example, calling join_words() does the following. Enter some words (. to stop): > hello > world > . hello world
Thankyou this was very helpful :) I also need to write functions that find the average_stolen using single argument called data and also write a function called get_borough_frequency where 2 arguments called borough and number and this should create a dictionary of the unique boroughs as the key and the corresponding value of total number of animals stolen in that borough . Any help would be great , thanks
