I'm using Codeblocks 13.12 in Windows. I want to compile and run c++ files with the console inputs are automatically extracted from a file. More importantly, I do not want to change the code to read files. I just have written codes to read them from the console. Any change in settings?

But when i got to the point where I needed to install the SDL image extension library I thought I had everything correct but when I tried running a program using it I got errors. The non-extension SDL apps work just fine but when I try using SDL_image functions in my code I get problems, although when I begin typing the function the name shows up and i do not get issues with the .h, I feel its a link issue because I get errors such as:
ld.exe||cannot find -lSDL_image|
ld.exe||cannot find -lSDL_image|
||=== Build finished: 2 errors, 0 warnings (0 minutes, 0 seconds) ===|
I'm confident I have my /includes installed correctly. Also I was unable to find the 1.2 version for the Img extension so i reluctantly went ahead with 2.0 if that is perhaps causing issues.

I've recently started to learn C++ and I'm using codeblocks as my IDE, but I keep getting problems with AVG free edition picking up random pieces of code as Trojans ?! I've put an example of some code that sets it off below, and the error message I get. Is there anyway I can set AVG not to trigger with any codeblocks coding I've done? I guess I could tell AVG not to trigger for that folder, if that's even possible?

I upgraded to code::blocks and now I have the errors while trying to install sfml and sdl (to use in a dual project): Codeblocks libs:Permission Denied
Codeblocks libs is a custom folder I created and copied libs from the lib folders to because I got the same errors in the actual folders and thought it might be because of their location. What should I do?
The user will be allowed to pick:
-the number of problems they want to do
-the type of problem (addition, subtraction, multiplication, division)
-the range of numbers for the problems (like 0 to 9, -100 to 100, etc.) [random numbers in the range]
Your program will then display the given number of problems and get the answer from the user. It will tell the user it they are correct or not. If they are incorrect, it will print the correct answer.
After the given number of problems are displayed, the program will give the user the final number correct and percentage correct. The user will be asked if they want to go again. If so, you will reprompt the user for all the information and run again.
I came up with code thinking I was going in the right direction but it doesn't work correctly at all. We have to use functions. My main issue is how do i call variables from another function so all of the functions work together. I repeat I don't understand parameters and calling functions. here's the code:
#include <iostream>
#include <cstdlib>
#include <iomanip>
using namespace std;
int get_user_range(int &x, int &y);

I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?
One of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows:
John K. 99, 87, 57, 89, 90, 95
Amanda B. Jones 100, 88, 76, 99, 86, 92
etc..
The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the last (2) at 30% each.
Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

I have a program where I will read in a certain .txt file, such as "financial_data.txt" and I will be doing some sorting with this data.
I want my program to write out the sorted data to an output file and I want the name of the output file to be based off of the input name. For example, since my input file is "financial_data.txt", I want the output file name to be "financial_data_out.txt".

I have code that reads an input file and generates an output file .For reading the input file we have a xml file.If there is an error while reading or writing the output file the an errored file is generated. But in the errrored file the fields are not coming as in accordance with the reader xml . They are coming randomly . In the module for reading and writing the errored file list is being used . What should be done to write in the errored file as the reader xml fields.

I'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
// Password Log
#include <iostream.h>
#include <fstream.h>
#include <string>
#include <time.h>
using namespace std;
ofstream login;
[Code] ....
What my problem is when I choose "Input new login info" it automatically inputs I have no clue, and calls next program.
Following is the program I wrote it basically takes 9 inputs and then save them into binary file. then print out the data stored in binary data and find inverse of it then print the inverse out. but its stuck in a loop somewhere.
Code:
#include <stdio.h>
int main() {
int a[3][3],i,j;
float determinant=0;
int x;
FILE *fp = fopen ("file.bin", "wb");

I am reading in a file where each line contains two octal numbers separated by a comma (and perhaps a whitespace). I would like to read these lines into a two dimensional array. So for example
E19, 2A4
9423, F15
would be Code: {{E19, 2A4},{9423, F15}}
Is there a way to check how many lines are in the file so I could initialize my array to the proper length? How would I obtain an octal number with more than one character? So get would grab a single character, but how would I grab however many characters prior to the comma as a single value?
Currently I'm trying to write a program that searches a file named "Babynameranking.txt" for a persons name, sex, and ranking. I'm currently having trouble with just being able to search the first line of the text file, which is somewhat of a precursor to being able to finish the program. My current code is:
#include <iostream>
#include <fstream>
#include <string>
[Code]....
Anyways when I run the program I wind up getting an output of
-858993460 -858993460
Done
I'm thinking that because the text file is formatted like this(just an example):
1 Jacob32509 Emily 25048
2 Michael29666 Madison 22149
(the spaces between everything are actually tabbed over)
that it's the large amount of whitespace messing it up.
I finally accomplished what I'd asked for earlier.
I'm able to input data from txt file to c++ array.
the Text file contains around 60,000 lines "numbers" to be loaded into a c++ array to calculate some stuff.
I'm able to load 60,000 lines "txt file size 1.1MB" no problem, but sometimes when I try to load more lines "from a file around 1.4MB", the process terminates and gives me an error message "n.exe has stopped working, Windows is checking a solution to this problem" and Code::Block shows error "Process terminated with status -1073741819 "
I am trying to read from my input file Transactions.data which is set up as follows
V 250190
A 250190 2008 4 8788.00 0.00 000
and so on and so forth.
I am trying to read my V then go to switch (decision) to choose my case and preform further functions. My problem is that i cannot get past the first line so if it was
V 213400
V 123456
My code is supposed to check that the ID (213400) is valid then go on to the next line but it wont do that and prints out the first ID 6 times. My code is as follows:
char descision;
ifstream input;
input.open("Transaction.data");
if (input.fail()) {cout << "File could not be opened." << endl;}
input >> decision;

For particular assignment, I am asked to evaluate data from an inputfile, let it be named "infile.dat". Next, it is required to output to this same file, but with the name of this file altered to reflect the changes of data. For example, if I want to change the original file name to "changed_infile.dat.altered" by adding the "changed_" prefix and ".altered" suffix, how could this be done?
From my understanding, there are no functions in <fstream> that could change the file name. However, there is a rename function in <stdio>, but it's not exactly what I am looking for because I want to append a prefix and suffix to this existing inputfile name. Although I could apply a brute force method by simply doing rename("infile.dat", "changed_infile.dat.altered"), I want to have my program to work with various input files of different names.
