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.
C++ :: Student Registration System - File Updating
Feb 14, 2012I have been creating this program for a student registration system. For the file handling So far I can write in to a file , view all records, and search a single record. now i got the problem with updating details . my coding is as bellow ..
void file_update() {
int r;
struct student stu;
fstream stu_file;
cout <<"========Update Record======"<< endl;
stu_file.open("student.txt", ios::app );

My problem is it won't update the record. it just adding a new record.

May 9, 2013I am doing something wrong since for me 4 threads perform 2 times slower then 1.I have 2 vectors with bunch of data to process, there is no concurrency (not moving elements and are independent of each other) so i just need to calculate some data from one and copy result in another.

C/C++ :: Student ADT - How To Delete A Record
Feb 24, 2014My 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.
Student.h:
#include <iostream>
#include <cstdlib>
using namespace std;
#ifndef _STUDENT_H_
#define _STUDENT_H_
struct Student {

C :: Add More Student Information To The Specific Txt File?
Mar 12, 2013I'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.

C/C++ :: Writing And Sorting Student Report
Sep 27, 2014I'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.
C :: Trying To Match Student ID With Highest Score Along With Grade
Nov 25, 2013I 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.

C++ :: Student Database - Ifstream And Ofstream Operators
Apr 23, 2013I've been working on a student data base that reads in the students name, birth date, social security, and department name (or major). I have all these items in the header files respectively; nameType, dateType, personType, and studentType.
I am now to create another header file called HWONEHEADER that contains the functions showMenu, loadStudent, insertStudent, searchByName, and SaveStudents. This is how far ive gotten
#ifndef HW
#define HW
#include <iostream>
#include <fstream>
#include <iomanip>
#include "studentType.h"
[Code] .....
Here is the cpp file i have.
int main() {
studentType department;
cin>>department;
cout<<department;
[Code] .....
I need with the HWONEHEADER using the ifstream and ofstream operators to load all the students information into a file called student.dat I'am extremely confused because i can't find anything in my textbook about using ifstream and ofstream operators.

C++ :: Stuck On Student Project / Classes And Objects
Aug 28, 2014Working on a project for a c++ class and got a bit stuck.
What I am trying to do is include a class for calculating home square footage in a program I have written for my last project. When I do this, I get errors in codeblocks, on lines 74 and 87, "expected ; before 'box', and 'box' was not declared, respectively. Unsure what my snafu is... I had these two programs separate and both run without errors until I combine the two into one program.
C++ :: Manipulate Array Of Student Record Objects
May 15, 2014Create 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).
