C/C++ :: Application Which Reads Input From Server And Write To A File
May 6, 2014
Currently I'm working on a application which reads the input from the server and write to a file. Message stored in server : idle_message="维杰PC时钟" key_prompt="在按键"
Server will send a xml reply with encode type as "UTF-8". In my code I'm store in a char array. [ char * ch = "idle_message="缁存澃PC鏃堕挓" key_prompt="鍦ㄦ寜閿" msg came from server and copied from vs2005 watch point] After this I'm writing the same to a file in my desk using the API WriteFile. When i open the file in Editplus below is the content.
idle_message="维杰PC时钟" key_prompt="在按键" Again I'm trying to read the file and storing into the char array. Below is the content viewed by the watchpoint in VS2005.
idle_message="缁存澃PC鏃堕挓" key_prompt="鍦ㄦ寜閿? I'm trying to find the starting and ending chinese char and I'm converting that char to wchar_t using the API mcstowcs() for display, its coming as completely junk chars.
I can able to every place the chinese char are different. how to overcome this problem.

I am trying to write a program for class that reads from an input file the month, year & total collected. I am using notepad for the input file.
This is what the notepad file looks like
-----------------------------------
March 2013 63924.62
Why does it give me random numbers in the output rather than what the notepad has?
Also, the outfile is completely blank.
#include <iostream>
#include <iomanip>
#include <fstream>

I need to write a program that reads four float numbers from the input.txt file, then it prints out the greatest of the four numbers into the output.txt file. I did everything, but the numbers don't print out.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile;
ofstream outFile;
float number1, number2, number3, number4;

Write a program that reads data from a file (use the attached data file). These data are a student name and 3 test scores. The program should calculate the average of the 3 test scores, and display the name, 3 test scores, and the average to the monitor.
Useful tips:
a) Include the following header files: iostream, fstream, iomanip, and string
b) The name of the data file is “datafile.txt”, you need to save the file in the same folder of the source file.
c) use the manipulators (setw, setprecision, setfill, showpoint, fixed) to format the average with 1 digits after decimal point as following.
d) Use character ‘ ’ for tab.

I have an application that reads a process and return values from it. The problem it works fine with small processes but i have some processes that are about 1GB or even 2GB and when i try to read such big processes the application crashes. I'm trying to find a way to read the process memory in chunks of maximum 10 MB. The read code looks like:
Code:
HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, entry.th32ProcessID);
unsigned char *p = NULL;
MEMORY_BASIC_INFORMATION info;
for (p = NULL; VirtualQueryEx(hProcess, p, &info, sizeof(info)) == sizeof(info); p += info.RegionSize)
[Code] ....
This reads the info.regionsize which can be as large as 100 MB. Is there any way to read it in chunks ?

I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?

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>
[Code]....

I have a lab with the following instructions:
Manually create an input text file called Lab22BInput.txt with the following data:
Dove
Doe
Alston
Zebra
Egg
Write a program that will read the names from the input file. Print out each of the names read to the screen. The program should go through the list of names and determine which comes 1st in the alphabet. The program should determine how many letters are in this name. Print out the name that comes first in the alphabet and the length of the name.
I have created the input file, and the data correctly outputs to the screen when I run the program. However, I do not know what kind of logic to use to sort them alphabetically and determine the amounts of characters.
So far I have the following:
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
string str1, str2, str3, str4, str5;
[Code]...

I am trying to build a c++ that reads user input and arrange letters in ascending order.
for example, if the user input: Hello my name is Moe! the output will be: !aeeehillmmmnoos (ascending order)
my problem is that when i input hello my name is moe the output will be ehllo (not completing other letters) also when i change class size to 50, it outputs unknown weird letters.
This is my code:
#define CLASS_SIZE 10
#include <stdio.h>
#include <iostream>
void bubbleSortAWriteToB(const char a[], char b[]);
using namespace std;
int main(void){
int i;

I want to open one new CMD from console application, write text into the new CMD and then coming back to the control on the old cmd. (like interactively working on the both)
look into the below code
Process P1 = Process.Start(@"C:WINDOWSsystem32cmd.exe");
P1.StartInfo.RedirectStandardInput = true;
P1.StartInfo.RedirectStandardOutput = true;
P1.StartInfo.UseShellExecute = false;
StreamWriter wr = P1.StandardInput;
wr.WriteLine("First line in New Cmd");
Console.WriteLine("First line in Old Cmd");
wr.WriteLine("Second line in New Cmd");
Console.WriteLine("Second line in Old Cmd");
it is giving the exception "StandardIn has not been redirected"

I am attempting to break up a file into smaller chunks and have it process the different parts of the file in parallel to speed up the entire process. I was thinking maybe 4 chunks at a time. How do I get my program to do this? Is there a good book explaining parallel processing in C?

I've been working on a program that displays the number of digits in each line of a file, but I feel stuck. Take for example a file that contains these characters:
6347aaa9
54j
811111
6a
709
And I'm trying to display a result like this
1 //that's the number of the line 5 //the number of digits
2 2
3 6
4 1
5 3
Here's what I've written so far:
Code:
#include<stdio.h>
int main() {
char a=0;
int number_of_digits=0, linescount=0, num, number_of_digits_per_line=0;
FILE *inputFile;
if(!(inputFile=fopen("C:TestTest.txt","r")))
[Code]..
I also thought of using fgets and strlen but I am not very good with them and couldn't get the program to work correctly. It did work but it displayed all characters, letters included, not only digits.

Ben has been administering a MBTI personality test. Now he has all the responses, but the task of scoring and compiling results seems daunting. The personality test* is a series of 70 questions for which the available responses are ‘A’ and ‘B’. Based upon the answers to the 70 questions, a personality profile is determined, categorizing the degree to which the responses place the person on four scales:
Extrovert vs. Introvert (E/I)
Sensation vs. iNtuition (S/N)
Thinking vs. Feeling (T/F)
Judging vs. Perceiving (J/P).
Each of the 70 questions relates to one of the four scales, with an ‘A’ response indicating the first of the corresponding pair (E, S, T, or J) and a ‘B’ indicating the second (I, N, F, or P). For instance, an ‘A’ response on the question: At a party do you:
A. Interact with many, including strangers
B. Interact with a few, known to you indicates an Extrovert rather than an Introvert; just the opposite for a ‘B’.
For this test, each question is designed to influence one of the four scales as follows:
questions 1, 8, 15, 22, 29 … are used to determine E/I,
questions 2, 9, 16, 23, 30 … and 3, 10, 17, 24, 31 … to determine S/N,
questions 4, 11, 18, 25, 32 … and 5, 12, 19, 26, 33 … to determine T/F, and
questions 6, 13, 20, 27, 34 … and 7, 14, 21, 28, 35 … to determine J/P.
Notice these come in sequences of “every 7th” question.
The goal of the test is to determine which end of each of the four scales a person leans, and to thus classify him/her based on those leanings (e.g., as ENFJ, INTJ, etc.). Since Ben would also like an indication of how strongly the test taker fell into each of the four, the program should print the percentage of ‘A’ responses for that scale.
Input for this program should come from a file responses.txt. The first line of the file will contain a single integer, n, indicating the number of test results to follow. Each of the following n lines will contain the first name of the test taker, a single blank, his/her last name, a single blank, then the 70 responses he/she gave on the test. Although the test instructions indicate that the results are most valid when all questions are answered, sometimes respondents leave questions blank. In that case, a dash appears at the corresponding place in the list of responses.
Output for the program should be written to the file types.txt. It should include a well-formatted report listing, for each test taker, his/her name, the percentage of ‘A’ responses in each scale, and the resulting personality type. A tie within a scale should result in a dash (‘-‘) for that part of the personality type.

Is there any way to input a picture into an application? I want to make the console of my C++ program display an image across it for a short while. The picture in mind is a gif. If there is no way to make it display in the console, is there a way to make only the image and not the webpage pop up on the screen?
I am trying to replicate the Skyfall "M gets hacked" scene. But this would be useful for other purposes as well.
I am not familiar with using header files or any other files other than the .cpp file and I only use one .cpp file for all my programs.

I am trying to make a simple login program that reads username and password from a text file.
In my text file I have:
name1;pass1
name2;pass2
name3;pass3
name4;pass4
name5;pass5
Everything is working okay with name1 and pass1, but if I try to log in with different credentials, for example name2 and pass2 it says "invalid details"
Here is my code:
string user, chuser;
string pass, chpass;
string los;
ifstream loginData("logindata.txt");
cout << "Please type in your username:" << endl;
getline(cin, user);

Here is my code and basically these are the steps. I feel like we have something good to work on but we keep getting errors.
a. Data to the program is input from a file of an unspecified length; that is, the program does not know in advance how many numbers are in the file.
b. Save the output of the program in a file.
c. Modify the function getNumber so that it reads a number from the input file (opened in the function main), outputs the number to the output file (opened in the function main), and sends
the number read to the function main. Print only 10 numbers per line.
d. Have the program find the sum and average of the numbers.
e. Modify the function printResult so that it outputs the final results to the output file (opened in the function main). Other than outputting the appropriate counts, this new definition of the function printResult should also output the sum and average of the numbers.

I seem to be missing a concept or 2 here ... I am tasked with writing a program that reads text from a file and outputs each line to the screen as well as to another file PRECEDED by a line number ...
In addition, I have to Print the line number at the start of the line and right-adjusted in a field of 3 spaces ...
Follow the line number with a colon then 1 space, then the text of the line.
Another kicker, is I have to grab the data 1 character at a time and write code to ignore leading blanks on each line.
Here is what I have so far:
#include <iostream>
#include <conio.h>
#include <fstream>
#include <string>
#include <cstdlib>
#include <cctype>
using namespace std;
int main() {
char next;
int count = 0;
[Code] ....
