I'm still learning intro to C language. Currently I'm having problem with my code. The task is to ask user to input information about staff and write them into a text file. The problem occur when:
1) output in text/.exe file display random characters.
2) Data obtained from New_Staff unable to pass into Export_Profile.
3) a new output will overwrite the existing information in the text/.exe file
4) the delete function unable to delete correctly after the first time i delete a staff information in text file.
I am working on my final project for my intro to c++. Its a simple program where you buy a car, choose parts for it, see the price of it in total, buying option, and to view past records.
So my problem lies with displaying the records. For some reason(doesn't many how many records there are) the very last record displays again without the "Model" part, but displays the rest of them fine. In other words, there are 2 problems, the last record is displayed twice, 2nd that added record displayed is missing the "model"(this problem doesn't matter really if you can solve the first problem, but would still like to know why it does that).
I tried debugging it and I believe the problem lies with the --------while(fName.good()). It just decides to repeat it again even though in the text file, it does not have that extra record.
My 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.
i want to create 100 gmail accounts instantaneously....what i want from you guys is i have written a program that create a text file i want that once i give the program the imput of 1 it should delete the first 3 lines from the file i.e. the first account details coz that is already been created and shift the rest of it 3 lines upwards after that i'll write a javascript that will automatically fill and create the accounts with those names in web browser.....my lil program is here:
In my project i need to update the attn_dateTimeOut in database.After i updated it will automatic delete the specific row record that had been updated. I had two question:
1) in my database there are a few table is assign not null."attn_dateTimeOut" is a table that haven insert any record. When i update it using below code,it work and can update but it comes out error.Error show "record cannot be null".
2) I want t make it when i updated the "attn_dateTimeOut",it will auto delete the row of updated record.I do usign back code "DeleteRecord" but it nothing change!How should i do?
Here my code:
private void txt_proximity_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == (char)13) { TMPB_attn row_TMPN_attn = BusinessLogicLayer.TMS_GET_PROXIMITY_VALID_TO_USE(txt_proximity.Text); if (!String.IsNullOrEmpty(txt_proximity.Text)) {
I have a Gridview ,in that one of the Column is DropDownList .I have 10 Records in my Grid and my DropDown Values are like this 1,2,3....10.This is the format to store my DropDown values ,if i delete 4th Row ,then my DropDown Values are Changed like 1,2,3,4....9.This is my task ,but i'm getting this format 1,2,3,--,5...10.
The program i wrote can run but did not work. I want to delete a line from the textfile "StaffList.txt" but when i cin the name, for example "Ben". After the program ran finished and i open the textfile, the name "Ben" and the whole line is still inside the textfile! I have created the "temp.txt" file before i run the program.

I'm trying to make a simple phonebook app that can show contacts, add, and delete. I'm pretty new to C++ and fstream functions, deleting a line in my bool erase() function?
General Purpose: Delete all "white spaces" in text file, until the read-in char is _not_ a whitespace (mark as start of text file).
Problem: Cannot seem to shift char's over properly. (I think my problem is the inner loop - however other code may lead to this problem - I do not know)
Code:
#include <fstream> #include <iostream> using namespace std;
bool trimWhiteSpace(fstream &file, char * charMemoryBlock) { if (!file.is_open()) {
How to validate the data if the data already exist in the table record in c#?
For example I wanted to add the student roll no. if roll no. is 134 and if we are adding rollno. 134 student then we get the warning like roll no. 134 is already exist ....
I have a program I have to do that counts the number of words in a text file. I have tried the code on 2 computers now since my programming teacher told me the code was fine. Here is my code:
#include <iostream> #include <string> #include <fstream> using namespace std; int main() { ifstream infile; infile.open("tj.text" , ios::in);
read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2 139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
1. first my professor required me NOT to change the MAIN function(because he made it)
2. I have to make 3 getlogs() STRING FUNCTIONS:
a. string getlogs(); - accepts no paramters, SHOWS ALL THE CONTENTS OF TEXT FILE b. string getLogs(const string & a); - accepts 1 parameter -SHOWS ONLY THE LINE WHICH CONTAINS THE SPECIFIED DATE FROM MAIN FUNCTION which is "2014-08-01" c. string getLogs(const string & b, const string & c); - accepts 2 parameters, SHOWS ONLY THE LINES FROM THE DATE START to DATE END specified at THE MAIN FUNCTION which is date start-"2014-08-01";DateEnd = "2014-08-10";
Code to write data(Double type e.g 12345.67891) in text file like pattern given below. Remember to put tab between each column.
----------------------------------------------------- Column1 Column2 Column3 Value 1 Value 2 Value 3 Value 4 Value 5 Value 6 Value 7 Value 8 Value 9 ----------------------------------------------------
I have a program that saves all information temporarily into memory (into the array), however, I need a permanent save solution. I have the full program working correctly, formatted perfectly, but it's missing the file array to file output.
Essentially, whenever I'm presented with the menu I'll be able to add entries, search by last name, show the entire list, and exit and save. Whenever I select option 4 the program should save to a file "address_book.txt". Whenever I reload the program, it should load from "address_book.txt" and populate the array with the preexisting data.
My question is focused on how and where I should implement the file output. What I have thus far:
#include <iostream> #include <string.h> //Required to use string compare #include <fstream> //Eventually used to store array into file using namespace std; class AddBook{
