I am trying to copy the stats from the save file "lol.txt" to main. I posted what the contents of the file below, but for some reason the I get for output jiberish and I cannot seem to figure out why.

I need a way to count lines in a .dat file using fscanf. I must use a regex to check that the characters in the file are alphanumeric. In essence I need to count the ' ' character. I know fscanf ignores this character. I need to exit if it detects anything other than alphanumeric with the digit that is "problem" along with the line number. My .dat file is:
Code:
howard jim dave
joe
(
Maggie My fileCheck.c is: Code: #include "main.h"
int fileCheck(FILE *fp)
{
int ret_val;
int line_count = 0;
char file[BUFF];
[Code]...
The output I am getting is:
Code:
file opened Digit: ( is not an alphanumeric character on line: 5 Program will exit! File closed As you can see, the character "(" is not on the 5th line but the 3rd. It is the 5th "string."
I also wanted to show the regex I am using.
Code:
#define to_find "^[a-zA-Z0-9]+$"
How this can be accomplished?
I am trying to read the name, phone number and address from a file ... Here is the code but it doesn't work and i don't know where is the problem ...

int phoneNumber;
char address[50];

The program is supposed to read in a text file, load it into an array and assign a character to each number in the array (so for this I'm thinking I'll be creating 2 arrays, an int array with the numbers read in from the file, and a char array with the characters assigned to the numbers). It will then print these two arrays. It's then supposed to go through the initial int array and search for any numbers whose values differ from their neighboring values by more than one, if such a value is found, it's supposed to give the number the value of the average of it's neighboring values. It's supposed to make all these corrections and then assign characters to these corrected numbers and print out both arrays.
How to load the array from the file. My textbook seems to do a good job of covering arrays and files, but it doesn't really bring them together and talk about building arrays from files. Here is what the file looks like, the first number is the size of the array.

What is the most efficient (fastest) way to load data from a file on HDD to RAM? (which would allow to only load a limited section of that file - eg. load only half of the file etc.)

What is the best / most efficient way to load polymorphic data from a file? I thought you could have an enumeration and for each item to load from a file you could have an integer at the start specifying the type of data, but I think there must be a better way I'm just not sure what.
Example of what I mean:
//The syntax isn't really that important for explanation
class base;
class a: base, b: base;
enum polymorphicType {
A,
B
};
and in the loading code you would have (this is the bit I think could be improved):
polymorphicType t;
File >> t;
if(t == A) {
newObject = new A;
} else if(t == B) {
newObject = new B;
}
I think there is probably a more efficient/better way of doing this I am just unaware of it.

This is a simple example from and old Lafore C++ book, with a few tweaks by me. The point is simple. Save object person to a *.dat file, exit the program, then start up program again, open up *.dat file, and load contents.
The first problem is the compiler is printing a bunch of Asian characters to the file (is this normal?)
The second problem is, it's not loading the object as it should, giving me a bunch of gibberish.

Heres what I am suppose to do, So it doesnt seem hard to understand my messy code!
1. Gotta load the file "FactoryData.txt"
2. Load all values in my 2D array (array[5][3])
3. Print out the array to ensure that the copying went by well.
Heres my problem:
1. The for loops is REALLY off in my eyes. From my knowledge (correct me if im wrong), its suppose to be for(r=0;r<5;r++) not <=. BUT somehow im getting the results I want (in terms of formatting). HERE IS MY OUTPUT

I am doing a project in C++ - a simple data base (with "one table"). I want to build that data base using a LIFO or FIFO list, but this doesn't matter here
The only problem I have is that the structure of the data base is not "locked" in the code of the program, but when the program starts, it is "loaded / implemented" from a "configuration file" called "data.txt".
So the user, before she or he runs my program opens the file "data.txt" and writes the structure of the data base that se/he wants to create. This means that one time my program can be used to create a data base of students with fields such as "name / surname / gender / age / idnumber / university" but the next time it can be used for a data base of CD's with fields like - "author / release date / no. of tracks / etc.".

I want to display a bmp file of resolution 600*420 (using c compiler like code block ) by manual loading. I tried to display the image by loading the pixel value. but this method has a limitation that it take up pixel value of image upto 64kb size.
So now i am trying to load it manually. What are the steps that i has to follow, what are the header files that i has to use ?

I'm struggling loading a class (and it's two derived classes) from an input file. I'm trying to create an array of class objects (and derived objects) and then load them based upon what is in the file.
Main class: Code: class Book

string sTitle;

Basically if the getline get's a P it's supposed to create a new object using the PrintedBook derived class and then store it to an array, if the getline get's to the "A" it's supposed to create an AudioBook object.
What I'm struggling with is writing something to parse the file line by line and create the objects on the fly and then store them into the array.
I've been making a multilayer game for a while and have a config that the game loads for the IP and stuff. I just recently put all the loading stuff into a function just so its easier to go through the code, but now the game isn't really working. It works fine on my computer connecting to the server myself, but when someone else tries to do it it seems like the game is working like it says the IP and everything from the config. When it tries to connect it either doesn't work or crashes just saying the program stopped working. Here is the code... I don't know if this is what is causing it to not work or something else.
string LoadConfig(int &loadPort, bool &fullscreen) {
string file;
string loadIP;
vector<string> fileLines;

I am currently working on a project that requires me to "load the data in the file into array at the beginning of the program."
I have a text file with data, and I need to populate an array with the information. From then on, I am supposed to be able to add, display, and search that array. However, I can't figure out how to add the data from the file into an array. I was trying to find out how to search the text file itself. So it threw me off balance and I've been staring so long at the screen I can't really focus.
I want to load a file to rich text box component. I have this line:

I probably write it wrong, but I can't remember the correct way. In examples I only see that instead of -> dot is used, but it doesn't work either.

View 1 Replies View RelatedI have two classes, productListType and buyerListType, that are each basically linked lists. To create the linked list for an object of productListType, I successfully wrote a non-class function createProductList to read the product data from a text file. The class definition for buyerListType has a data member productBoughtRecord that is of type productListType to aggregate the details of the products purchased by a particular buyer during transactions. I decided to make productBoughtRecord a pointer since the contents of this data member would wax and wane over the course of several transactions, depending on the amount and frequency of payments made by the buyer. I have provided a rough sketch of the class below:
class buyerListType
{
public:
setCustomerInfo( ....., productListType* p);
.
.
.
private:
productListType* productBoughtRecord;
.
.
};
I'm similarly trying to write a non-class function createBuyerList to load the record of customers from a text file. How do I determine what the value of the formal parameter p in member function setCustomerInfo is, in order to be able to set the data member productBoughtRecord? take into consideration that an object of class buyerListType would have multiple buyers with varying amounts of products purchased.
I have been playing around with .txt and .dat files lately. I only manage to load the files, but I don't seem to be able to load files using a variable.
Also modifying the data after it is imported is also currently problematic. I know how to go about the process without the need to import anything, but whenever I import the data I am having trouble modifying/ editing the ".txt" or ".dat" data.

#include <fstream>

ifstream file;

char in_file_name[8], out_file_name[8];

I am trying to scan a list of 3 by 4 numbers and the 4 numbers of each column to the 4 different arrays, so if I read from the data above, i get an array with numbers 1,5,8; another with 2,6,9 and so on. Is it how its done in my code?
I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:
FILE *d;
d=fopen("t.dat","rb");
where a, n are all strings.
fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,..(etc)..,&n);
