C++ :: Array Traversal - Output Each Student And Score That Falls Below Average
Oct 24, 2013
How to traverse through this array and output each student and score that falls below the average. I think I may have the method down for traversing through the list to find the "total score" however, before proceeding under a possible wrong presumption, I would like confirmation as to whether or not I'm understanding this or botching this concept.
void dispLowScore(struct payload *arrayStart , //first element of array
struct payload *arrayEnd ) //last element of array {
int studentCount; //total number of students in list/array
int totalScore ; //accumulated value of all scores added together
float averageScore; //totalScore / studentCount

I have to get the average score for each student. And modify my avgmarks function and write the marks to a output txt file.
Code:
#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
int bubble(int*,int);
void filewrite();
void avgmarks();
void fileprint();
void filesort();
void rollin();

I need to get Students to input there Name And Score > and for me to output the grade. This works but I want to tidy this up so I can see all the names and grades when the program finishes.
#include "stdafx.h"

#include <conio.h>
#include <iostream>
#include <stdlib.h>
#include <string>

#include <stdio.h>
float total, avg, max, min;
float judge[4];
int index;
int array[4];
int main() {
total = 0.0;
max = array[0];
min = array[0];
[Code] ....
I dont understand how to make the array when it prints out only print out the final average and the final maximum score with the final minimum score but what its doing at the moment is just giving an average for each individual score taken...
Minimum and maximum scores are displaying 0.0
And it displays these things 4 times in a row i just want it to be displayed once.

it compiles and runs, it gives me the average and the highest score but says lowest is 0 even though 0 is never entered.
Write a program which uses an array of 5 scores and calculates the average score, the highest score and the lowest score.
#include <iostream>
using namespace std;
int getHighest(int [], int);
int getSmallest(int [], int);
double getAverage(int [], int);
int count;
int numbers;

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
Press any key to continue...

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.

Create a 1-D Array to hold a set of exam scores:
55 74 93 84 64 72 69 78 87 84 72 33 83 68 62 51 88 90
Write a program to do the following tasks:
1. Display scores in rows of four(4) scores.
2. Calculate average score and display.
3. Find Lowest score and display.
4. Find Highest score and display.
5. Find the deviation of each score, and display the score and its deviation.
6. Find the Standard Deviation and Display
7. How many scores are within One Standard Deviation
So I have the average down, but I am getting stuck at the part of displaying the highest and lowest score. Every time I run the program I get two giant negative numbers for both of them. I put all the scores into a .txt file and I just opened in through the program.
#include "TCHAR.h"
#include <iostream>
#include <fstream>
#include <iomanip>

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;

I was tasked with creating a program that asks for the scores of three gamers then takes these scores and outputs the highest. I THINK I have the other parts down but I don't know how to get the program to compare the scores and output the highest without having to write a long list of commands comparing playerone to playertwo, then player one to playerthree, then player two to playerone, etc.
#include <iostream>
using namespace std;
int main () {
int playerOne, playerTwo, playerThree;
cout << "Please enter score for Player One: ";

Create an application to manipulate an array of student record objects. A student record will consist of a name (first, middle, and last), an ID number (9 numeric digits, cannot be more or less), an address (street, city, state, and 5 digit Zip code), and a phone number (3 digit area code and 7 digit number). The application will support an array of students. The user will be allowed to enter records from the keyboard, sort records by either name (last, first, middle) or by ID, save the records to a disk file (name supplied by user), and read the records from a disk file (name again supplied by user).
Create a fixed length string that must check that the length of the string is the required length. The fixed length class should be done as a template with the number of characters as the template argument. From this fixed length string, derive a class to hold digits of a fixed length.
Create component classes as necessary to use together to implement the student record class.
Use either the array template created in an earlier lab to handle the array or you may use the vector class from the STL to handle the array of student record objects.
The maximum number of students will be 25 (it may be less).

This program is supposed to take integer score inputs from the keyboard into an array and use a sentinel of -999 to end the process.It should call a show() function which passes the array and displays the name and number of the integer for the output.
# include <iostream>
using namespace std;
int main() {
int score(double array1[], int numbers);

I am getting an error in the for loop r<number which states "Error identifier "numbers" is undefined" and on my array1 "Error identifier "array1" us undefined" also in my for loop.

I must write a function that has a one dimensional double array and the number of values in the array as its arguments. Normalize the values. I must also print the maximum, minimum, average and numbers of values above the average in the array.
The equation that computes the normalized value from a value x is:
Normalized x= (x-min(array))/(max(array)-min(array))
My code does not print the correct normalized value, average and values above average.
Code:
#include <stdio.h>
int findMax( double array1[], int num_elements) // This function computes the maximum value of the array
{
int i, max=-32000;
for (i=0; i<num_elements; i++)

I am trying to average the negative numbers and positive number and of course the total average.
This will read in a list of n values, where n is not known ahead of time. The number of values read into the array will be saved in n.
vector<int> readList() {
std::vector<int> result;
ifstream inFile;
inFile.open("setA.txt");
for (int x; inFile >> x; ) {
result.push_back(x);

array is a one-dimensional array of integers and n is the number of elements in that array that contain valid data values. Both of these are input parameters to the function. The function must calculate 1) the average of the n integers in array, storing the result in ave; 2) the average of the positive numbers (> 0), storing the result in avePos, and 3) the average of the negative numbers (< 0), storing the result in aveNeg.
void avgs (std::vector &array, int &ave, int &avePos, int &aveNeg) {
int sum = 0, pos_sum = 0, neg_sum = 0, pos_count = 0, neg_count = 0;
for (auto i : array) {
sum += i;
if (i > 0) { pos_sum += i; ++pos_count; }

I am attempting to write a program that takes a number(picked by the user) of test scores in an array then calculates the average and outputs the number of passed and failed tests.
On a side note I am attempting to use array notation in the main function and pointer notation in the other functions

#include<iomanip>
using namespace std;
int numScores;
int counter = 0;

I used a BFS to simulate graph-join structure in a C++ code, and had a binary tree that asks the user e.g. to insert a node in the tree among other options, anyhow, I reached a point where I should pass a set of vertices from the graph to the tree, but how to do so. So I wanted to ask is such a thing possible? i.e. passing vertices from a graph to a tree automatically (no user involvement is needed)?

Traversal of binary search tree. In my header file there is a function setTraversal (public) and private print file. As I understood from teacher's explanation, my setTraversal function should call the recursive print function and print the list depending on selected order (pre,in or post-order). I still cannot get my head around what should be in setTraversal function definition. All resources I read last two days explain each order separately (preorder, inorder, postorder). How can I combine them? Here is my code:
#include "NodeTypeBST.h"
#include <iostream>
enum TravType {PRE, IN, POST};
template<class T>
class BST

I am getting the hang of it pretty well. I created a program that asks the user to input arrays. Now, I need to calculate the average of the inputted arrays, and I need to place them in order from low to high. I have been struggling with doing these two parts for a while now and now decided that the book is not useful, I need some from some actual programmers. I attached my program.
My program printed here!
Code:
#include

using
