Develop a function that finds the greatest difference between two consecutive elements stored in an array. Develop a 9 element array of doubles to test your code. Print to the screen which two numbers have the greatest difference as well as the value of the difference. Finally include an overloaded version of the function that will work if the array is composed of integers. Include your code used to test this function.
I am trying to use a class Student and declare it as a list type. I can pushback but without changing the List.h or Node.h how can I print the data in list2?
I have written the following function to calculate GCD of floating point numbers, but when I run this for (111.6, 46.5), the calculation of fmod(a,b) in the funciton starts giving the wrong result after 2 recursive calls. I am unable to find the error here.
How can I calculate GCF of many numbers? I thought I could calculate two by two numbers, but it not seems to be a very effective idea. There is my function:
int gcf (unsigned int x, unsigned int y) { return (y == 0) ? x : gcf (y, x % y); }
I have to write a program that sorts numbers from least to greatest. The way that it has to sort them is:
1) The program assigns the first number to be a minimum 2) If the next number is less than the minimum is now that number and they switch places. (We keep on looking if the number next to it is not smaller) 3) The program also gets the index of the minimum number 4) We keep on going until it is in order.
// Sort.cpp : Defines the entry point for the console application. //
#include "stdafx.h" #include <iostream> #include <vector> using namespace std; void Sort(vector<int>&input); int _tmain(int argc, _TCHAR* argv[]){ vector <int> input;
//****************************************************************************** // GradeCalculator.cpp // Input: Student Grades in Each Category // Output: Final Grade, Numerical Grade, Witty Comment // Final Grade Calculator // This program calculates a final grade using a formula, assigns a // corresponding letter grade, and outputs a "witty" comment to the user. //******************************************************************************
My assignment for class was to create a Student ADT. I have three files. First one is Student.h which defines a Student record and has the prototypes of the functions that can be used with Student. I have Student.cc which is where the functions are actually declared. And my final file is testStudent.cc where the "main" function is that is creating a Student and callign all of the functions to make sure they work properly.
I have all of the functions working properly, except for my destroyStudentRecord function. It is supposed to deallocate the record, but I am unsure of how to actually do this. The current implementation appears to only deallocate the firstName field, as when you display the record after deallocationg it, everything still shows up except the first name. I have tried deallocating each field of the record before deallocating the record itself and that gave me the biggest list of errors I have ever seen.
I realize the implementation of some things in here might be a bit odd, but this is exactly how we are required to do things for this assignment and nothing about the implementation can really be changed unless something is actually just plain wrong(which is of course a possibility as I am quite new to this!). As I said though, everything else is working exactly as it should be, so my only issue at all is with actually deleting the record once I have created one.
I'm trying to add more student information to the specific txt file. I did struct my student information and separated it with an array with max size of 200.
The inside of my current file looks like
Toshi Aka Nonal Donald
The first one represent student[0] and next one is student[1] and so on till student[199]. Right now, only 4 space is occupied, which means the array has information till student[3] but not from student[4] (I guess it has null condition).
What I want to do is, I want to add a new student information to student[4] and till student[199] once at each time.
So, my prompt will look like Would like to add a new student? Y/N (if yes goes to below statement and exit if NO) Hi. Please enter the information of new student. ___________ Student added. Please press any key to continue.
If the key is pressed, it goes back to my initial prompt and continues till I press N.
I sure I'm not using for loop to do this thing, because I'm adding student name one by one.
However, the array is already occupied by other student name till student[3] so, I want to add a new student information to student[4] (I don't want to overwrite the current information). And if student[4] is occupied, then [5] and so on.
i wnt to display student who get highest marks among them...i have code for finding maximum marks from them but don't kne how to print only top 5 student...
Code:
static void Main(string[] args) { Console.WriteLine("Please Enter Number of Students :"); int n = Convert.ToInt32(Console.ReadLine()); StudentDetails[] student = new StudentDetails[n]; for (int row = 0; row < n; row++) { Console.WriteLine("Please Enter Student name :");
I've remade a program to store student database using linked list. When I try to display the list of student with their information (It displays nothing)
For Example i have made a text file included some students data. Now i want to change just a single student data. That file should remain same just that student's data replace.
So I have to store a student Id and gpa and name in a linked list. I keep getting error messages.
Like: lab 20.cpp(43): error C2628: 'Student' followed by 'int' is illegal (did you forget a ';'?) (43): error C3874: return type of 'main' should be 'int' instead of 'Student' (71): error C2664: 'Student::Student(const Student &)' : cannot convert parameter 1 from 'int' to 'const Student &' Reason: cannot convert from 'int' to 'const Student' No constructor could take the source type, or constructor overload resolution was ambiguous
I'm trying to write a table (2D array) with a string of random chars in one row for the student names, six other rows for the project numbers and random numbers for the grades.Then calculate the averages of grades per student and per project, add them as the last row and the last column. And write a menu of 4 options:
1- sort per student names (alphabetical order) 2- sort per student grades (in increasing order) 3- sort per project grades ( in increasing order) 4- exit
The program must continue execution after displaying any report, need to use an infinite loop, it exits only if the chosen 'exit'.
I am trying to correlate the student's highest score with that student's ID. The old code is in blue and the new code is in green which includes a sort. The particular information in question is in red.
Ide1
Code: #include <stdio.h> int main(void) { /*Set up two arrays to include up to 50 elements each.*/ int st_numval_id[50] = {0}, st_val_tstscr[50]= {0}, i = 0, j = 0, temp;
[Code] .....
Enter the student's id and test score:
/*After the following input, then enter 0 to end the input*/
Student ID Test Score Letter Grade ------------ ----------- -------------- 1653 77 C 1945 72 C 1020 50 F 1955 92 A 1900 81 B
ABOVE AVERAGE STUDENTS
Ave Test Score Students Above Ave Number of: A's B's C's D's F's ----------- ---------- --------- --- --- --- --- --- 62.00 4 1 1 2 0 1
THE STUDENT WITH THE HIGHEST TEST SCORE
Student ID Test Score Letter Grade --------- ---------- ------------ 1900 0 F
I dont know how to modify the previous record that i have done in the Add Student function. i searched from different sites and got this code for modifying a record in a text file. But, i cant figure it out why its not working.
The programme has to be a linked list to gather student info, (ie name, lastname, student no, and three grade); the first and last name must use malloc correctly, there must be an insert and delete function and a printfunction. and they must print out in alphabetical order.
