I tried to make the program read from a file text the first name or last name but o cant seem to get it. i tried alot of different ways. how can i get the array of structure code to read form a file?
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;
const int NUM_STUDENTS = 17;
const int NUM_QUIZZES = 10;
const int NUM_EXAMS = 5;

So the premise of my code is to read in a 2d array from a .txt. The array is a game board but the first two lines are what determine the size of the board. After i read it in i want it to find wherever te character "U" is, and then display the array but only showing U and whats around it. Problem is i cant get the array to print the right size and the code for displaying the U is not working either.
ifstream inputFile;
int boardSizeRow;
int boardSizeCol;
inputFile.open("C:UsersMichaelDesktopfileboard2.txt");
inputFile >> boardSizeRow;
inputFile >> boardSizeCol;
inputFile.get();
[Code]...

I would like to write a complete structure array to a file and read it back, recovering all the data. I have tried the following:
Code:

#define NUM 256

typedef struct foo_s {
int intA;
int intB;

1.) A loop to prompt the user if they would like to place another order
2.) At least one user-defined function
3.) An enumerated data type, array or struct (structure)
I did one of these three, it's a "DO WHILE" loop asking users if they want to make another order, it's right at the beginning of the code.

For an assignment I have to write a program which basically converts 8 bit binary numbers to ASCII and outputs the assembled text. Here's the catch:
The 8-bit binary numbers are provided by some external file (which only contains 8 bit binary numbers); the name and hence length is not known. The external file is called with a pointer upon execution
(./"conversion program" < external_file.in).
I'm getting the 8 bits as a string, calculate/convert decimals, output char type. HOW do I know when to stop the loop? If I just pick an insanely high number I get random stuff at the end; no boundaries obviousely lead to an infinite loop. Can I determine the lenght of this random ext file somehow nonetheless?
Is it possible to create a vector which dynamically adjusts itself until there are no more strings = end of the file?
I need to be able to actually read my encrypted file..
I have the decryption code and works perfectly when running it through console app c++.
But, the way I decrypt is to decrypt from a file, and create a new file which is decrypted.

I am trying to use arithmetic on structure members read from separate text files into separate functions. I'm trying to do the math in the main function after calling the other two functions. I'm trying to divide nato_attack by pact_defence.
The warning I'm getting is: both are being used uninitialized in this function.
The goal is to read/write the info in the text files and to use them as any other variable, i.e. add, subtract, etc. in other locations in my code, i.e. functions, modules.
I "borrowed" most of this code from a youtube lesson and modified it for my needs.
Below is the contents of the two text files and my code.

I am trying to use struct to store variables from a text file and use them in the main program. I have first tried running the program without using struct and declaring the variables within the main program and it runs fine. But after using struct, it gives no compilation error and a segmentation fault as output. Also, if the size of file/variable size is unknown can I declare variables as char string[]??
The code is as below:
Code:
#include<stdio.h>
struct test {

I've got some code in C++ that does some basic analysis on price data and I run it from the cmd prompt. One of the functions I had built to read in the data is as follows:
void ReadPricesFromFile(constchar*filename,std::vector<PriceInfo>&prices)
{std::ifstreaminput(filename);
input>>prices;}
How would one merge this type of code into a Qt GUI? Ideally, I'd like to use something like QFileDialog to open up a folder with my data files, select a file, and then read the file that the user selects. Would the main.cpp look something like this?
int main (int argc, char *argv []) {
QApplication prog (argc, argv);
QPushButton *load_button = new QPushbutton ("Load File");
QObject:: connect (load_button, SIGNAL (clicked()), &prog, SLOT ( (ReadPricesfromFile function?);
load_button-> show ();
return prog.exec ();}
I am trying to read data from more than one file at once. The files are different types e.g. one is a text file one is an xml file like so, StudentInformation.txt, CollegeInformation.xml. The files are all stored in one place, in this case on the D drive of a local computer. I am trying to locate any files in the D drive with a file extension of .txt or of .xml (there may be more than two of these files in the future, so I'm trying to allow for that). Then I want to open all of these files, extract the information and output all the information in one display window. I want all the information from these two or more files to be displayed together in the display window.
Here is the code so far. It is throwing up errors.
//Load from txt files
private void btnLoad_Click(object sender, RoutedEventArgs e)
{
IEnumerable<string> fileContents = Directory.EnumerateFiles("D:\", "*.*", SearchOption.TopDirectoryOnly)
.Select(x => new FileInfo(x))
.Where(x => x.Extension == ".xml" || x.Extension == ".txt")
.Select(file => ParseFile(file));}

The error it throws up is:

View 3 Replies View RelatedAs a starter project I want convert a Neural net app from "AI Techniques for Game Programming (2002 Buckland)" to a Visual C++ CLI Forms application. I have created the interface and now I have to rewrite the in/output routines, amongst other things.
First question I have has to do with variable initialization used by Buckland. Code looks like this:
Excerpt from header file (CNeuralNet.h):
//-------------------------------------------------------------------
//define neuron struct
//-------------------------------------------------------------------
struct SNeuron
{
//the number of inputs into the neuron
int m_NumInputs;
//the weights for each input
vector<double>m_vecWeight;

Question I have: what is the the function of ": m_NumInputs(NumInputs+1)" after the method declaration? Buckland does this in many places in his code. In this case it's a struct, but he does it with classes too.

How to structure something like Game Menu. I was googling and did not find anything useful. I am coding a little game and Menu part with few sections like START GAME - SELECT LEVEL - SETTINGS (SOUND, MUSIC AND VIBRATION ON/OF) - CREDITS - EXIT.

But when i print A[3][3], it does not contain the correct value, but I strange value, like -36893488147419103000 .My idea was to pass line by line of the file, including the values that were not " ", to get only the numbers.
I have assignment which requires me to print out and array code and a pseudo code. I dont no what a pseudo code is,.
