C++ :: Trying To Get Void Getscore To Read A File And Report
Jun 30, 2014
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
// Function prototype
void getScore(int &);
void calcAverage(int, int, int, int, int);
[Code] ....
this is what I have so far but I a stuck. The name of the file is grades.txt.I am trying to get the program to read 5 grades from a file and report back lowest grade that will be dropped and average of 4 left. It runs but is not reading the file.

I'm having trouble with how to find the count and sum of all numbers.
The file, called question1.txt, contains numbers:
1
2
3
4
5
0
0
0
-2
-2
Here's my code:
Code:
#include <stdio.h>
#include <stdlib.h>
int main (void)
{
FILE* spIn;
FILE* spOut; //for output file
int numIn;

I'm writing a program that writes to a report in a text file. It uses a struct but with no array. How can I write this so that the report comes out as it should because as of now after i removed the brackets from record which is the variable of the struct my report isn't printing right.

Here is the assignment... Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;
and define two namespace globalTypes (tys and fys) for the function :
class_level deriveClassLevel(int num_of_credits) ;
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy. And the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
and this is the code I have so far...
#include <cstdlib>
#include <iostream>
#include <cctype>
#include <fstream>
using namespace std;
enum class_level {FRESHMAN, SOPHOMORE,JUNIOR,SENIOR};
class_level classLevel;
[Code] .....
My main question is did I use the namespaces and enum correctly? And my second question is whats the best way to input the data from the text file? This is really where I get stuck.

The first namespace globalType tys should derive the class level based on a two year school policy.
The second namespace globalType fys should derive the class level based on a four year school policy.
So I basically did it in parts and got everything working and then had to make the namespace so I had this:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
[Code] ......
I know I have to clean it up and change it but it ran like it was suppose to. Then I tried adding the global namespaces and I this:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;
[Code] ....
with this i keep getting an error saying tys::deriveClassLevel: must return a value and tys::fys::deriveClassLevel: must return a value. I have been messing around with this part and struggling I thought I used the namespace to run the if statements with the criteria for the years of school. Basically I have been stuck for awhile and trying to change things around but I cant seem to get it to work.

Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.
….
}
I did this in parts so I got it working with a four year criteria without the user defined name spaces.
include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
[Code] ....
So that worked fine then I tried with name spaces -
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;
[Code] ....
I know I have some stuff to mess around with but I am currently stuck with two errors, first -
Error1error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartupC:UsersstephenDocumentsVisual Studio 2013ProjectsinputConsoleApplication1MSVCRTD.lib(crtexe.obj)ConsoleApplication1

I am having trouble with outputing on the file2.
here is what I have:
Code:
#include<iostream>
#include<fstream>
using namespace std;
ifstream file1;

I have a .txt file that I need to input into two parallel arrays. The first array needs to be on dimension and the second needs to be two dimensions.
This is a sample from the .txt file:

Austria052.853.154.6
Belgium30.430.327.525.3

Greece30.326.925.013.1
Hungary032.521.818.6
Iceland068.271.666.0
this is what I have for code so far:
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
using namespace std;
const int SIZE = 40;
const int COLUMN = 5;
void getData(ifstream& inf, string n[], double tstData[][COLUMN], int count);
[Code] .....
when I compile and run the code and have it display it does not read the first item into the 1-d array, instead it appears to read the 4th number from the left into the 1-d array and then into the second spot in the 2-d array, then again in its proper place and finally it has this number repeating through the rest of the arrays:
-92559631349317830000000000000000000000000000000000000000000.00 followed by the number 59.7 from the .txt and the long number again.

I declared all functions in header file, such as:
bool readCase();
bool meshing();
bool readMesh();
bool calculateFlowfield();
bool readFlowfield();
bool calculateEvaporation();
And then I define them in separated .cpp files, each .cpp file include the header, but I got multiple definition error, why?
Even the int main() function, which only decalred and defined once got this error, why?

I want to read the contents of a file block (512 bytes) by block using low I/O read statements. Each record is 64 bytes long and has a pre-defined structure. The first 4 bytes are an unsigned integer; the next 20 bytes are ascii text, etc.
I have a buffer which I can access with buf[0] to buf[63] to read the first record and then buf[64] to buf[127] for the second, etc. However, I was wondering how to map a record so that I can refer to an integer as an integer and a float as float, etc. I can't create a struct and move the 64 bytes to it, as I will have alllignment/padding problems.
What is the standard way to deal with records in C?

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'.
Here's what I have:
#include <ctime>
#include <string>
#include <iomanip>
#include <iostream>
using namespace std;
ints=12,p=6;
stringnames[20];
[Code] ....
And then, I need to show interactively the same report with all types of sorting:
sort table by any row, (user enters the row number)
sort table by any column. (user enters the col number)
sort table sorted by student names as well.

I created a dataset that contains an empty dataTable that has several columns , and then I created a new report that is linked to this datatable using the report wizard. In my form there is a button when clicked should fill the datatable mentioned above ( I checked if it is being filled by displaying its content in a dataGridView and by firing a messagebox that is triggered when 'datatable.rows.count > 0' ).
The reason that the datatable is initially empty is that it depends on some conditions that may alter the query used to fill it.
But finally when I load the form that has the report viewer it only has the names of the columns of the datatable and no contents. What's wrong ?

The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.
How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?
If "Y" Than Inputs Are Taken From Next Line Else Input Ends.
But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.
Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Code:
readlength=2500000
start=0
finish=25000000
cutoff=20000
samplingfreq=250000
poles=10
filterpadding=500
}
[code]....
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.
