C++ :: Unable To Input Data From TXT File Into Array Program
Mar 26, 2013
I'm having issues trying to input data from a .txt file into my array program. The whole program takes the name, # of goals and assists, adds them together to get points, and then puts in a given + or - rating. The program works except for the data input.
Also, this is an alphabetical "Unsorted" list, but is there a way to order the list based on point value and be able to display that as well as a separate "Ordered" list?
#include <iostream>
#include <iomanip>
#include <fstream>
#define NUM_PLAY 30
using namespace std;
int buildArrays(int[], int[], int[]);
void printArrays(string[], int[], int[], int[], int);
[Code]...
And this is the .txt file. Order is Players Name, Goals, Assists, Plus/Minus rating. The points are added when points = goals + assists (Should be in the main coding above).

I'm having some problems with Input to an array from a file. I think that i need to make a new array for every instance of the loop but i can't figure out how.
Participator class
void Participator::read(ifstream &stream){
getline(stream, name);
getline(stream, address);
stream >> paid;
}ParticipatorRegister class
void ParticipatorRregister::readFromFile(){

I am new to C++ and I am having an issue reading in a 2 Dimensional array from a data file. I am very close to reading it in perfectly except for one issue, the loop is ignoring the first value from the data file.
This is the code I have so far:
#include <iostream>
#include <string>
#include <cctype>
#include <algorithm>
#include <functional>
#include <conio.h>
#include <iomanip>
#include <string>
#include <fstream>
[Code]...
This is the values from the data file:
300 450 500 210
510 600 750 400
627 100 420 430
530 621 730 530
200 050 058 200
100 082 920 290
When the Program shows my array it comes up as:
450 500 210 510
600 750 400 627
100 420 430 530
621 730 530 200
050 058 200 100
082 920 290 0
Every array location is moved up one, like the program just completely ignored the 300 at the beginning.

I am having trouble in reading data from my text file and print it out exactly like how it looks like in the text file. The problem im having is it will not read the last y Coordinates of the point. it keep reading the second last point for y coordinates which is wrong.
my text file is
0.0 0.0
0.0 1.0
1.0 0.0(but it read until here)
0.0 0.0(suppose to read the last point which is here)
For your information, this is my 1st year degree assignment in C programming. It is to create a program which can read text file (manually create) and print it out in a program and calculate the area for the polygon using ADT function ( .c and .h files)
*This is the code for my read file function*
Basically this accepts a Polygon and a file pointer as parameters. It reads the polygon point data from the file, pass the read data to plg_new() to create a new Polygon and returns the new Polygon created.
Code:
polygon *plg_read(polygon *New_polygon, FILE *Coord) {
int i;
int numberofvertices=0;
int count=0;
char filename[50];
double xCoor[50], yCoor[50];
[Code]....
This is the second function my polygon new code. This ADT function basically creates a new Polygon with malloc(), initialize all ADT data members with its parameter values and returns the Polygon.
Code:
polygon *plg_new(double *xCoordinates, double *yCoordinates, int numberOfVertices) {
int x;
polygon *New_poly = (polygon *)malloc(sizeof (polygon));
if(New_poly->xCoordinates == NULL || New_poly->yCoordinates == NULL) {
free(New_poly);
[Code]....
This is the rest of the code if you need to refer to other codings.
Code:
/**
*@file polygon.c
*@brief Functions for polygon / Struct has polygon numberOfVertices, polygon *xCoordinates and polygon *yCoordinates
*@author: Tan Xian Yao
*@id: 4323440
*@date: 22/04/2014

I'm trying to append data to a CFile using FILE* But when execute the application, it always give error saying "No such file or directory". I can actually see the file created but it just keep giving error "No such file or directory".
Is the file being lock or the file just created so it can not be find by fstream(FILE*)? or the file mode is wrong?
Below is the code:
[QUOTE]
void SaveDocument(CString strFile) {
CFile file;
if( !file.Open(strFile, CFile::modeCreate | CFile::modeWrite | CFile::shareDenyNone)) {
CArchive ar(&file, CArchive::store);
// save now.
MyClass.Serialise(ar);
[Code]...
Attached is the printscreen of the FILE* pointer. the pointer is evaluated as bad pointer. Why the FILE* pointer not able point to the file being created?

I have written a CFD program that final results store at several 2D arrays. For instance, temperature of a square plate. For every point of plate i and j (i,j), I have a temperature amount. On the other hand, these temperatures change by time.
theSpace.TheCells[i, j,0].Temperature
I would like to save these data into an excel file and each sheet contains data for specific time (for example, an excel file with 50 sheets that cell number shows the coordinate of a point and the value in it is the temperature and next time step data's will be in the next sheet of current workbook )
I was thinking my code should be something like the following note, but it doesn't work:
// Implement time loop
int counter = 0;
for (int step= 1; step<= MaxSteps; step++) {
// call Excel output method
ExportData(ResultsArray,step,nx,ny);

I have a program that stores health information the user inputs, one person at a time. The program works perfectly with the exception of storing the data...I need to open a file and read what health data it has in it already, if any, but store the new changes, and appended data to the array of structures, to the data in memory. All of the information is only saved back in the file once the program terminates. I'm not sure how to go about doing this, so I am also not sure what to put in the function for "Save and Exit" that the user can choose in order to exit the program.
Code:
#include "stdio.h"
#include "stdlib.h"
#include "string.h"
struct strdatabase
{
char first[20];
char last[20];
char gender[2];
[Code]...
I tried playing around with this bit of code, but I'm not sure if I'm even on the right track.
Code:
FILE *fp;
fp = fopen ("students.txt","rb"); fseek(fp, 0, SEEK_END);
long pos = ftell(fp);
fseek(fp, 0, SEEK_SET);
char *bytes = malloc(pos);
fread(bytes, pos, 1, fp);
fclose(fp);

I want to input data into text file while not deleting the original data in the file and I use something as
ofstream writefile;
writefile.open("example1.txt");
if (writefile.is_open()) {
for(j=0; j<N; j++) {
[Code] ....
But this will delete the original data.

Ben has been administering a MBTI personality test. Now he has all the responses, but the task of scoring and compiling results seems daunting. The personality test* is a series of 70 questions for which the available responses are ‘A’ and ‘B’. Based upon the answers to the 70 questions, a personality profile is determined, categorizing the degree to which the responses place the person on four scales:
Extrovert vs. Introvert (E/I)
Sensation vs. iNtuition (S/N)
Thinking vs. Feeling (T/F)
Judging vs. Perceiving (J/P).
Each of the 70 questions relates to one of the four scales, with an ‘A’ response indicating the first of the corresponding pair (E, S, T, or J) and a ‘B’ indicating the second (I, N, F, or P). For instance, an ‘A’ response on the question: At a party do you:
A. Interact with many, including strangers
B. Interact with a few, known to you indicates an Extrovert rather than an Introvert; just the opposite for a ‘B’.
For this test, each question is designed to influence one of the four scales as follows:
questions 1, 8, 15, 22, 29 … are used to determine E/I,
questions 2, 9, 16, 23, 30 … and 3, 10, 17, 24, 31 … to determine S/N,
questions 4, 11, 18, 25, 32 … and 5, 12, 19, 26, 33 … to determine T/F, and
questions 6, 13, 20, 27, 34 … and 7, 14, 21, 28, 35 … to determine J/P.
Notice these come in sequences of “every 7th” question.
The goal of the test is to determine which end of each of the four scales a person leans, and to thus classify him/her based on those leanings (e.g., as ENFJ, INTJ, etc.). Since Ben would also like an indication of how strongly the test taker fell into each of the four, the program should print the percentage of ‘A’ responses for that scale.
Input for this program should come from a file responses.txt. The first line of the file will contain a single integer, n, indicating the number of test results to follow. Each of the following n lines will contain the first name of the test taker, a single blank, his/her last name, a single blank, then the 70 responses he/she gave on the test. Although the test instructions indicate that the results are most valid when all questions are answered, sometimes respondents leave questions blank. In that case, a dash appears at the corresponding place in the list of responses.
Output for the program should be written to the file types.txt. It should include a well-formatted report listing, for each test taker, his/her name, the percentage of ‘A’ responses in each scale, and the resulting personality type. A tie within a scale should result in a dash (‘-‘) for that part of the personality type.

I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?

How would I check for proper data type when someone is to input a value into the program? Ex:
int i;
string a;
cout << "Enter a number: ";
cin >> i;
cout >> "Enter a string: ";
cin >> a;
How would you check to make sure that int i would be an actual number and not a letter like "a"?

In class we were asked to create a C++ BTree program that would allow a user to input the following data types and then store said data in a .txt file:
0. ID 8 bytes
1. First name 30 char
2. Last Name 30 char
3. Street Address one 30 char
4. Street Adress two 30 char
5. City 30 char
6. State 20 char
7. Zip 10 char
8. Country 30 char
(I'm not particularly asking for full code, pseudo code would also be great). I had a great deal of my work done, unfortunately, the computer I was working on crashed, corrupting my files.

// Here is my code for displaying the data from the text file into a 2d array and height next to it, but I am not able to diaplay the height from 60 to 76 next to the row of the 2d array, as shown in the table below. This is my program:
Recently the health authorities have listed a new way to calculate the body mass index (BMI) of an individual.
Values of 20 – 24 are classified as normal, 25-29 as overweight, and 30-34 as heavy.
The table below is a portion of a typical BMI table.
BMI:202122232425262728293031323334
Height:
60102108113118123128133138143149154159164169174
61106111116122127132138143148153159164169175180
.
.
.
MY task is to write a program that does the following things:
1.Produce the table by reading in the data from bmi.txt (on Moodle) into a 2-D array.
2. Display the table neatly on the screen, with row and column headings. The BMI should go from 20 to 34. The height should go from 60 to 76 inches.
3. Prompt the use for their height (in inches) and their weight.
4. Make the program print the closest BMI.
If their weight is lower than the values on the table, use 20 as the BMI.
If their weight is higher than the values on the table, use 34 as the BMI.
5.Loop the program so the user can find more BMI’s.
