C++ :: Read Uneven Records From File Into Class

Oct 20, 2014

The following shows a sample input file for class called Training. How can I read these uneven records in to class?

An array of Training (based on the number read from the file) should be created dynamically then load all the details into each Training object.

C :: Pointer Jumping Over Address In Uneven Array

Jan 1, 2015

Why my pointer skips over the colour addresses, it jumps to the next size address when I use Pointer++. I have tried changing the the char array to 4 bytes instead of 32 and whatnot but it doesn't work.

If I set the Pointer = the first colour address, it skips over the size addresses and only get the colour addresses. I know using 2 arrays would easily solve everything, but sadly I must use only 1.

I'll post whatever relevant code here:

C :: Using Struct To Pull Records From A Colon Delimited File

Dec 15, 2014

I'm trying to write a C program that will take a file that is delimited by colons and separate it out in to 5 sections:

I have the struct code in place but not sure how to actually store each of the 5 parts in memory. Here is the code below:

C++ :: Read And Write Multiple Class Objects From File - Fstream Won't Work Correctly

Apr 28, 2014

So I have a small program which is supposed to write and read multiple objects from a file, but for some reason it doesn't write the information when I use "fstream" to create the object from the fstream class, but it does when I use "ofstream". Also, it doesn't read the information from the file no matter if I use "fstream" or "ifstream". I watched a video where this exact code worked just fine, but it just won't work when I run it. I'm using Dev C++ 4.9.9.2, I don't know if that has anything to do with it, I also tried it with Code::Blocks, didn't work either.

Here's the code.

#include <iostream>
#include <fstream>
using namespace std;
class Person

C :: Read Contents Of A File Using Low I/O Read Statements

May 15, 2013

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?

C# :: Dataset Loading Most Recent Records?

May 16, 2014

what I need to do is load a dataset with the most recent record for each item in the database table. Each item has an ID, location ID and date along with some numeric data. the item ID, location ID, and date is referenced in each record of the table. So each item will have multiple records with different dates that could be anything. To make things worse there may be the same item in multiple locations. and each locations items most recent record needs to loaded in to the dateset and then displayed in a data grid. At a later time there will be a location sort as well so only items in a particular location or group of locations will be loaded. More question on the data grid to come.
