C# :: Looping Through Text File And Recalculating Some Values

Jan 20, 2014

I have chosen C# as our language . Students have to enter a name of a recipe, followed by the number of people it will serve, followed by a list of ingredients for a recipe. This, then, needs to be exported to a text file. This bit I am fine with.

They then have to import the file back into C# and recalculate for a new number of people. This is the bit I am struggling with. The calculation is fine, I can do that. The issue is getting it to loop around each column of data to not only perform a calculation (I have just set it up to multiply by an entered value for now). I have set up a text file with the following data in it:

2 grams sugar
350 ml milk
4 tsp lemon
5 tsp vanilla
6 cloves garlic

I want it to come back with, (if multiplied by 2 for example) something like:

4 grams sugar
700 ml milk
8 tsp lemon
10 tsp vanilla
12 cloves garlic

At present, it comes back with

4 grams sugar
4 grams sugar
4 grams sugar
4 grams sugar
4 grams sugar

Code is below.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace ConsoleApplication1{

C++ :: Looping With Different Values?

Dec 9, 2013

I want to write a loop to check for prime numbers. So I'm going to check only numbers ending with 1,3,7,9.

So I need a loop that will increment with 2,4,2,2 and again 2,4,2,2...

What king of loop is best, a 'for loop' or a 'while' with switches in it or something else?

Basically I need to increment three times with 2 and then with 4, three times with 2 and then with 4...

C# :: How To Edit Hex Values Of A Text File

Jan 5, 2015

I have a report that's generated by a piece of software, and (I'm assuming because it was intended for Linux/Unix) when I open to read it in notepad, it has a bunch of funky symbols in it, and incorrect line feed characters instead of returns that windows uses.

I looked at the txt file with a hex editor and can see all the hex codes for the symbols I want deleted. One of the symbols 0A.

How can I do a "find and replace" command but do it with hex codes? These symbols cant be simply placed into my code file because VS does not know how to interpret it.

C++ :: Removing NULL Values In Text File

Sep 2, 2013

I have a measuring board that writes a .txt file in the following format:

board number;type;NUL;channel;measured value;date and time
DS207;5000007;NUL;0;20251;11.07.2013 12:30:02 MESZ
DS207;5000007;NUL;1;10159;11.07.2013 12:30:02 MESZ
DS207;5000007;NUL;4;27.18;11.07.2013 12:30:02 MESZ
DS207;5000007;NUL;0;20233;11.07.2013 12:35:02 MESZ
DS207;5000007;NUL;1;10149;11.07.2013 12:35:02 MESZ
DS207;5000007;NUL;4;27.31;11.07.2013 12:35:02 MESZ
DS207;5000007;NUL;0;20256;11.07.2013 12:40:02 MESZ
...

I would like to extract and analyse the data but the data behind the NUL entry is not accessible for me maybe due to the fact that NUL normally marks the end of a line. Is there a method to remove the NUL entries in this text file?

C++ :: Take Values From Text File And Store Them In Variable And Use For Later Calculation

I have a text file in the form

5502 5202.3
1523 2536.1
1254 1256.2
17846 8956.2 and so on

left one is time and right one is pressure, I need to show the time value as it is but i need to use the pressure value to calculate air speed. I don't know how to use the strings to pick up the list properly. I did the calculation formula for the air speed but i can't pick the pressure value up from the text file. here's what i did:

#include <iostream>
#include <fstream>

C/C++ :: How To Assign Values From Text File To Structure Of Arrays

Sep 5, 2014

have to do an election program in C.

There are 7 candidates and 365 votes in total. I need to do this using an array of structures. I need to read from a text file each of the names of the candidate and the number of votes they get. At the end i need to output the winner of the election.

Here is a sample of my code so far

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct candidates {
char name[20];
int votes;

[code]....

Here is a sample of my text file:

Robert Bloom
John Brown
Michelle Dawn
Michael Hall
Sean O’Rielly
Arthur Smith
Carl White

1 2 4 5 1 2 3 4 4 1 2 3 7 4 4 5 3 7 7 7 7 7 7 7 7 7

Each candidate gets +1 vote for their number electionCandidate[0] for each one he gets one vote and so on for the rest. 365 voters in total.

I was able to input the name for each Candidate from the text file. Now the problem is putting each vote to the corresponding candidate. Also any vote that is above 7 is a spoilt vote which i am trying to count in the above code. The code compiles but it crashes.

I am using while(!feof) but it seems that its not working or this is not the correct way.

C++ :: Looping In CPP Class File

Jan 4, 2014

I have a class with a .h and a .cpp file. (I'm unique!) In the .cpp file, I have a loop and a nested loop. It worked fine when it wasn't in a separate file. Now, the loops will not loop and the value found at the end is some random out of the all park number because no looping took place. I am positive that the conditions and variables are set properly.

C :: Possible To Mix Characters And Integer Values In A Text Document

Jul 23, 2013

I was just wondering whether or not it is possible to "mix" characters and integer values in a text document that is to be read by C.

I am to read and use values for length around the hip, neck and such, however, most of the tutoring examples I am finding online seem to strictly deal with either integers or characters alone.

Basically my text file looks a bit like:

Abdominal length: 90.000
Neck length: 26.500
and so on

So, before I move further into this subject, is it possible at all to isolate and use only the double values or will I have to format my text file differently?

C :: Read A Line From Screen / Takes ASCII Values From Entered Text And Edit It

May 10, 2013

This is a small program that reads a line from the screen, takes the ASCII values from the entered text, and edits it. Next, the ASCII values are reinterpreted (am i misspelling?) as text, and displayed. However, my final output has (allways?) at least 7 characters, even if you enter only one. I'm also trying to accomplish, that the part of the string which isn't filled, will be printed empty. In spaces.

compiled with -std=c99.

Code:
#include <stdio.h>
int main(){
int maxsize;

C/C++ :: Infinite Looping For Map?

Jan 13, 2015

I have been trying to get this piece of code to work but it seems to be running infinitely. What i'm trying to do is that whenever the iterator points to the map element, I check whether the element is 1 or 0. If it is 0, *do something*. But if it isn't, it should not do anything and proceed to the next element in the map.

//infinite loop - not working!
for (MapType::iterator p = pwCounter.begin(); p != pwCounter.end(); ++p) {
if (p->second.second != 1) {

C# :: Looping Through A Range Of IP Addresses

Feb 6, 2014

I want to take a starting IP on a local network, and loop through to an ending IP on a local network, pinging all the IP addresses in between. For instance, ping all IP addresses between 192.168.1.1 - 192.168.1.255 (user enters desired starting IP and ending IP in text boxes).

I have the ping functionality working, and i can make it all work with lots of messy string parsing.. but it seems sloppy to me.

I have to split the strings (start and end IP) to get the last octet, then subtract to get the range of IPs. Then loop through, adding 1 to the last octet, and converting back to a string each time.

The C# Ping class can use either a string or an IPaddress for its Send method. If I use IPAddress, I just have to convert it from the text box it originates in, but the adding 1 to the last octet in the loop is a hassle.

Anyway, I guess the only question I have is, if you had to loop through a range of IP addresses, how would YOU do it?

public Job(string ipStartIn, string ipEndIn) {
long ip1 = Convert.ToInt64(ipStartIn);
long ip2 = Convert.ToInt64(ipEndIn);
IPStart = new IPAddress(ip1);
IPEnd = new IPAddress (ip2);
this.deviceAlive = false;
