C# :: Calculating Averages - Display Employee Number And Average Of Three Test Grades
May 3, 2015
I have a project that I am working on and I have gotten stuck. I am getting a couple errors and would like to see how I can complete the program. Not very long of a program at that. My instructions are:
Write a program to calculate averages. Create a method named ReadData that will load a two dimensional array, named scoresArray, with the following data from a file:
132475.889.392.3
435686.383.498.3
479090.177.376.9
839373.976.389.3
556397.378.478.9
832987.365.377.2
271767.989.379.3
ReadData will have one argument, the scoresArray.
Create a method named DisplayAverages that will display the emplyee number (number starting 1324, 4356 etc) and the average of the three test grades. DisplayAverages will have one argument, the scoresArray. Your output should closely resemble the following.
Student #Test1Test2Test3Average
132475.889.392.385.8
etc, etc
Round averages to one decimal place. Passing arguments is important for this program. No global variables are allowed, except for the streamReader and the streamWriter. The scoresArray must be declared in Main and passed as an argument to the methods ReadData and DisplayAverages.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using LibUtil;
using System.IO;
using System.Text.RegularExpressions;
[Code] ....
When I run the following just to see where I am getting I get the following error:
UsersJoeDocumentsVisual Studio 2013ProjectsCIS110Program12Program12Prog
ram12Dat.txt was opened
Unhandled Exception: System.IndexOutOfRangeException: Index was outside the boun
ds of the array.

at Program12.Program.Main() in c:UsersJoeDocumentsVisual Studio 2013Proj
ectsCIS110Program12Program12Program.cs:line 24
Press any key to continue . . .
What am I missing here? I believe I have passed the arguments properly, but I am unable to declair the array within the bounds of the array?

The bottom three functions do not work. Nor are the finished to the extent. I do not know how the data members are being accessed and is only giving me the last output. The overall goal of this program is to output the highest grade with student name and age, lowest grade with student name and age, and the average of all grades. The file is given and is commented out for you to see what the file looks like.
// Header Files
#include <iostream>
#include <fstream>
using namespace std;
// Global Constants
const int STD_STR_LEN = 10;

This is a simple program I am building to find the average of 5 grades where the lowest grade is dropped. I created a function findLowest() which accepts the 5 grades as arguments, finds the lowest grade and returns it as "lowest". I have tried many different way to find the lowest number. Right now, I am working with if...then statements.
#include <iostream>
using namespace std;
void printMessage(); //Prototype for printMessage
void getScore(int&); //Prototype for getScore with reference variable
int findLowest(int,int,int,int,int,int &); //Prototype for findLowest with reference variable

Write a C++ program to output information for three students. The information stored in your program contains student’s first name, middle name, last name, and test score. The following shows the information for the three students, where test score is in the int type.
John Jacob Smith 78
Mary Jane Weems 82

Your program should declare three named string constants for the three students. Each constant contains the student’s first name, middle name, and last name. You may use three int variables to hold values for the three test scores. The first name, middle name, and last name of a student are then extracted using the substr() function shown in class. Your program should also compute the average (in floating-point number format) for the three test scores. The average score computed should be printed to the screen with 2 digits displayed after the decimal point.
The following shows the output from the program. Note that all the output is left-justified with 15 character positions reserved for each.
first name middlename lastname testscore average
John Jacob Smith 78 73.67
Mary Jane Weems 82 73.67
Dave Joe Dale 61 73.67

I need to write a program that prompts the user for 10 grades and then find the average. I have that part but I need to average to not include -1. How can I tell the program to not calculate -1 into the average.
#include <iostream>
using namespace std;
int main() {
//Declare variables
float grade[10]; // 10 array slots
int count;
float total = 0;
double average;

An instructor needs you to write a program that will compute the final average grades in her class. There are 5 students in the class. Each student must take 2 exams and 4 quizzes as part of their final grade. The weight of each toward the final grade is as follows:
Exam 1 – 30%
Exam 2 – 30% Quiz 1 – 10%
Quiz 2 – 10%
Quiz 3 – 10%
Quiz 4 – 10%
You must use arrays to store each students 3 digit ID number, exam scores and quiz scores. A multi-dimensional array is mandatory. Request from the user the information needed then output all of the information as well as the final average grade for each student.

Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be nearly the same as the data in the input file except that you will print the names as last_name, first_name and there will be one additional number at the end of each line: the average of the student's ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide where the last name comes first, then a comma and a space and then the first name. Use your read string function to read each name separately and then put them together into a larger correctly formatted string before trying to output them. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings.
This is how much I have so far:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
char* read_string(char* buffer, int max_size, FILE* fp);
int main(int argc, char *argv[]) {
FILE *fp_input, *fp_output;

OUTPUT
The player's batting average is: 0.347
The player's on-base percentage is: 0.375
The player's slugging percentage is:

I am working on a program that calculates the average of a list of test scores entered, with the list ended with a negative score (which is not calculated), as long as a user enters a name.
#include<iostream>
#include<string>
using namespace std;
int main() {
string name;
double score = 0.0; //user input score
[code]....
I have gotten the while loop to function. The problem lies in the calculation in the average of the test scores, such as when I enter the scores 87 76 90 -1 , which is supposed to give an average of 84.3 but my result when outputted is 86. what the problem is and what I can do to fix this error?

Now this issue is about calculating the average of numbers and displaying it in the out put.
The following numbers is what I have read in from a file. There are 7 lines all the same format, just different values of course.
132475.889.392.3
435686.383.498.3
The output will need to look like:
Student #Test1Test2Test3Average
132475.889.392.385.8
435686.383.498.389.3
My program thus far is: (omitted code to shorten post and remove irrelevant information.
I don't know if it is because I have been working on other things and forgot how to proceed with the calculations and display, but I am just stuck. I'm not sure how to have the program read the numbers from columns 2 through 5 and then divide by 3. As you can see in my DisplayAverages() method I should have the ConsoleWrite and WriteLines done properly.
static void Main()
{
double[,] scoresArray = new double[7,4];
LoadFile();
ReadData(scoresArray);
[Code]....
Should read columns 2-4 and then display the average in column 5.

I have created a program that allows for a user-defined number of test scores as input. After the user enters these scores, the program calculates the average test score. Here is my code:
#include <iostream>
#include <iomanip>
using namespace std;
// Function prototypes
double getAverage(double*, int);
[Code] .....
I am having trouble with the final part of my program. How do I pass the array of test scores to a function that calculates how many people got an A (90+) on the test? The final output should look like this:
The average of those scores is:
The number of A grades is:

Write a program that a prof can use to enter the test marks of several students and which calculates the average mark of each student. Ask the user how many students he has, then ask him to enter each student's marks. When 999 is entered, calculate the average mark for that student (not counting the 999) and print the average. Then go on to the next students until the marks for all students have been entered, calculated and the average printed.
Code:
#include<stdio.h>
main() {
float student,mark,total=0;
float a,b,c;
int num = 999;

Write a payroll program that prompts for the number of hours an employee worked, as well as the employee’s pay rate. If the employee worked for 40 hours or less, the gross pay is calculated by multiplying the number of hours worked by the pay rate. If the number of hours worked by the employee exceeds 40 hours, the employee should receive regular pay for the first 40 hours, and receive time-and-a-half pay for the hours in excess of 40. Display the calculated gross pay on the screen.
Continue to prompt for similar data for more employees and have the gross pay of each employee displayed, until there is no more employee data to process. Then display “Good Bye”.
Your solution must be separated into three source files (Interface, Implementation, and Test)

so in declaring a display function prototype only that displays a student test scores in the format (student name tab number of scores tab test scores )
is this right?

I have learnt about string class, file I/O and pointers. Now I am asked to write a program that includes the above topics, basically testing the ability to use dynamic arrays.
I've got 2 documents, namely "Students.txt" and "EnrollRecords.txt". "Students.txt" includes 40 students' info, which are university ID, programme names and their names. These 40 students are all BEng but from different departments.
E.g. 20141129 BEng(Civil) Tom Jerry
"EnrollRecords.txt" includes 166 data, which are course codes, university ID, respective scores in the test and GPA. In this document, the same student can have several scores of different courses' tests. So their uids repeat in it. And this document only contains the data of the Department of Computer Science. So students exist in the "Students.txt" may not exist in this document.
So my task is that the user enter a name (e.g. John), then the programme will know to find John and his uid, and get all the GPA of the courses that he has taken to calculate the average GPA.
E.g. 20147777 BEng(CompSc) John David //this is a John we are looking for in the "Students.txt"
//line 15 COMP1220 20147777 90 4 //so we find 3 courses in "ErollRecords.txt" that John has taken
//line 50 COMP1500 20147777 85 3.3
//line 88 ENGG2012 2014777 70 2.3
The programme should display :
20147777 3.2
To able to do anything for this task, I am asked to define 4 struct types:
struct Student {
int uid;
string programme;
string name;
[Code] ....
So now I am going to write a function queryD(Database d, string searchName) and any necessary functions in it. I am able to do the search part,
void queryD(Database d, string searchName) {
for (int i = 0; i < d.numberOfStudents; i++) {
if (d.students[i].name.substr(0, searchName.length()) == searchName) {
match_uid(d);
[Code] ....
But I struggle in how to match the uid in "Students.txt" and "EnrollRecords.txt" . Because there are repeated data for the same student in "ErollRecords.txt". So how am I gonna be able to match the uid and do the calculation? I get stuck in the for loop part...
