Hi, I cannot fix the 5 errors after trying to fix the code. Even after fixing the code it is giving me more errors which I don't understand how to fix. I tried reordering #include "student.h" and #include "bubble.h" in studentMain.cpp but it gave me more errors. Is this happening because I am compiling with the wrong command, I am compiling it all together like this: g++ studentMain.cpp bubble.cpp bubble.h student.h grades.txt. I have the modified code below and I can only edit the code in the studentMain.cpp file I cannot edit the code in the files bubble.cpp, bubble.h, and student.h:
//studentMain.cpp
#include <stdio.h>
#include <stdlib.h>
#include "student.h"
#include "bubble.h"
int main()
{
// Create an array of 19 student pointers
student *students[19];
// Allocate space for each student in the array
for (int i = 0; i < 19; i++) {
students[i] = (student *)malloc(sizeof(student));
}
// Read in the data from the file
FILE *fp = fopen("students.txt", "r");
if (fp == NULL) {
printf("Error opening file\n");
return 1;
}
for (int i = 0; i < 19; i++) {
fscanf(fp, "%s %s %d %d %d", students[i]->first, students[i]->last, &students[i]->exam1, &students[i]->exam2, &students[i]->exam3);
// Calculate the student's mean
students[i]->mean = (students[i]->exam1 + students[i]->exam2 + students[i]->exam3) / 3.0;
}
fclose(fp);
// Sort the students using the bubble sort
bubble(students, 19);

The correct way to compile your C++ files is by omitting the header files and any other non-source files like grades.txt in the g++ command. Just include the .cpp files. The header files will be automatically included by the preprocessor as specified in the #include directives.
Compile using:
g++ studentMain.cpp bubble.cpp -o output

- It's easy to get mixed up between latitude and longitude! Happily, at least sometimes, this is an easy fix to correct. Complete a method named fixLocation. fixLocation takes a Location object as its only parameter. Some of those location objects have their latitude and longitude swapped. If that's the case, correct them! Otherwise, leave them unaltered. You may be wondering: how will I know which locations are incorrect? The hint is that these are all locations from around the University of Illinois. That should help you determine when the latitude and longitude have been swapped. The Location object has Double latitude and longitude properties that you can access and modify in the usual way in Kotlin.arrow_forwardAs the first step in writing an application for the local book store, we will design and implement a Book class that will define the data structure of the application. Each book has a name, author, type (paperback, hardback, magazine), integer ID and pageCount. Provide some data validation in the appropriate method to ensure that the ID and pageCount are not negative. Design and implement a Book class with separation, i.e., separate all functions and methods into both the prototype and an implementation below the main. Provide constructor methods for Book(void), Book(name, author), and one for all components Book(name, author, type, ID, pageCount) Provide accessor (get and set) methods for each property as well as a display method. Provide data validation for the ID and pageCount in the appropriate methods. Provide a method to calculate the cost for buying books (with a 7.75% sales tax) according to the following chart: Hardcover: $29.95 per book Paperback:…arrow_forwardI have posted this multiple times and people keep giving me answers that don't correspond to the question or is unloadable.

- Hi, it is still giving me the same 5 errors as last time even after modifying the code.

Today we are asked to modify the GridWriter class by adding additional collection style functionality, to throw an exception in case of an error. The GridWriter class should get two new methods: public int size() should return the number of GridItems stored in the GridWriter public GridItem get(int index) should return the stored GridItems by index. Consider the following code. The first line creates a GridWriter object. Then two items are added to the GridWriter. The index of the items will be 0, and 1. Notice how the for loop uses the size and get methods to print out the areas of the two items GridWriter gw = new GridWriter(40, 50); gw.add(new MyCircle(10, 10, 9)); gw.add(new MyRectangle(40, 0, 10, 10)); for (int i = 0; i < gw.size(); i++) { System.out.println(gw.get(i).getArea()); } Once you have these two methods working you…arrow_forwardTests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass. section 10.4arrow_forward
- It will use a class called NameHelper (which you will write). This class will provide methods to load the data files and to fetch name rankings by year. The JavaFX class will be using NameHelper according to the following UML, so make sure your data helper has the methods defined below: What does the (~) mean in the attached diagram.arrow_forwardFollow all code styling and submission instructions as outlined for previous labs. Derive a MinHeap class from the BST class of your Lab 4 code. Define/Override only the Search/Insert/Delete methods in the new class. Write a new main for this lab which: Will only be a test program for the MinHeap. Declares and creates a MinHeap object as necessary. Declares and creates the Dollar objects as necessary. Inserts the 20 Dollar objects specified in Lab 4 in the same order. Performs all 4 traversals after the inserting the 10th and the last objects - in total there will be 8 outputs which should be clearly demarcated. No user input is necessary, no data validation is necessary. For submission - upload all class files from Lab 4 as necessary as well as your new MinHeap class and the main. Remember to also include adequate number of screenshots of the program execution. The Discussion forum will be monitored and responded to all week during the Finals. Office Hours will only be held on…arrow_forward
