The first two numbers are the Particle ID and its Energy, the rest of numbers are the loss of energy(different in number for every particle).
I have to elaborate 1000 events like this and to create a function able to read every line and to count the number of the loss energy measurement.
I use ifstream to read a file text, but my problem is: my program how to understand that it's passing to the new line? I have to divided every events in Arrays of different length, so i have to count each data for every particle and then create the array.
I would like to create program which will analyse bitmap so would need good concept to save data. I am interested about the theory and I realize that i must to think this carefully because bad concept could create insufficient memory or inefficient program. Basically I want my program work with HSV or HSL model so I would need to convert the bitmap to HSL, but I am not sure if I should convert it first and then analyse all pixels or should I start to analyse the bitmap and make the conversion to HSL during it. But my main question is what method to choose to save the data in memory.
Even that I would start with very small, it should work also with bigger image like image having 1200 or even 4200 px on height. So the program should first analyse all columns of pixels in the image so for example 1200x800 px image has 1200 columns. So I would like to know if is it possible to create such object which would have such structure like this
Obj->basicColumnData->black->columns[name]->group
and in the place of columns should be placed data for every column. I would look for groups of pixels in the column, so in the result the column x could bear e.g. 500 groups of information and every group should contain the range of pixels e.g. group 1 should contain y value from 0 to 20, group 2 should contain value from 25-27 and so on. So I would create 1200 columns bear many of groups. This would be contained in "black" or "white" member to contain the data. This is just simplified idea, but the whole object should contain next data not just basicColumnData... So there should be another members bearing information calculated from the selected data.
So my question is what kind of method of saving data use for this? Should I use heap and dynamic allocated memory or should I create custom class, which will define every member, but these members will have to be dynamic memory? With the dynamic memory is there problem that there could be not enough memory to create such big object?
I'm using an mbed micro-controller to retrieve register from Integra 1630 energy meter with modbus via a SIPEX SP485CS chip (RS485 level shiftier).
All the component and connection are working correctly.(Double checked) Using the same program with different reigster, i'm able to get good modbus reply from other type of energy meter with modbus. I always a register of 0x00 instead of good modbus reply.
#include "mbed.h" Serial RS485(p28,p27); DigitalOut ho(p26); int regvalue[9]; int main()
You are writing a program to calculate the area for 500 different measurements for a playground company in the region. The company must calculate square footage of each prospective playground, as well as the total cost to mulch each area. The cost of mulch changes frequently, so the company would like to be able to input the current cost per square foot of mulch each time they run the program. Since the quantity of data is large, the input should come from a file called “measurements.txt”. You can assume the file includes the length of each prospective playground, followed by the width. The file will be in the following format.
450300 120210 . . .
Ask the user the name of the file they would like to write to, as well as the current price of mulch per square foot. Output the area of each playground, along with the total price of mulch to the file that the user specifies. The playground company would like each column of output to be 20 characters in width. Each column should have an appropriate heading in the output file. You should format your output data appropriately. For example, for the input data displayed above, along with a $2.00 per square foot mulch price, the output would be:
Area Total Mulch Price 135000 $270000.00 25200 $50400.00
Assignment: Design a class to store measurements. The class should have two data items, feet and inches, both integers. The class must make sure that the number of inches never gets below zero or above 11. If inches is outside that range, adjust feet accordingly. (Yes this means feet might be a negative number.)
Create a default constructor and one which receives one integer, a number of inches.
Overload the following operators: addition, subtraction, equality, inequality, incrementation (both pre and post) (should add one to inches), and output (in the form of: F’I”)
Code: #include <iostream> using namespace std; class measurements {
private: int inches; double feet;

I'm trying to analyze Population Dynamics. I found some articles and read them but what kind of model i need to use. I tried Forest Fire model but i failed in modificating.
I am writing a program where I need to read a byte of char data and convert it into a text string of binary data that represents the hex value...
i.e. The char byte is 0x42 so I need a string that has 01000010 in it. I've written the following subroutine....
------------- My Subroutine ---------------------------------------------------------------------- void charbytetostring(char input, char *output){ int i, remainder; char BASE=0x2; int DIGITS=8; char digitsArray[3] = "01";
[Code] ....
When I submitted the byte 0x42 to the subroutine, the subroutine returned to the output variable 01000010... Life is good.
The next byte that came in was 0x91. When I submit this to the subroutine I get garbage out.
I am using a debugger and stepped through the subroutine a line at a time. When I feed it 0x42 I get what I expect for all variables at all points in the execution.
When I submit 0x91 When the line remainder = input % BASE; gets executed the remainder variable gets set to 0xFFFF (I expected 1). Also, when the next line gets executed..
input = input / BASE; I get C9 where I expected to get 48.
My question is, are there data limits on what can be used with the mod (%) operator? Or am I doing something more fundamentally incorrect?
I have written the following code to add data to text files which are required to store 3D scan data (I have to calculate the y-coordinate). My code seems to work except that it stops working when I want to create more than ten text files i.e. the directory I am trying to store them in will not hold any more than ten text files. Code is shown below.
#include <iostream> #include <fstream> using namespace std; int main() { int r = 0; int c = 0; int num[17][15] = { 0 }; [Code] ...

Am I missing anything or doing something wrong thats not causing it to page & only display 4 titles at a time?
I have a situation where I am accessing an ASP.NET Generic Handler to load data using JQuery. But since data loaded from Javascript is not visible to the search engine crawlers, I decided to load data from C# and then cache it for JQuery. My handler contains a lot of logic that I don't want to apply again on code behind. Here is my Handler code:
public void ProcessRequest(HttpContext context) { JavascriptSerializer jsonSerializer = new JavascriptSerializer(); string jsonString = string.Empty; context.Request.InputStream.Position = 0; using (var inputStream = new System.IO.StreamReader(context.Request.InputStream))
[Code] ....
I can call the function : getUserControlMarkup() from C# but I will have to apply some URL based conditions while calling it. The contentType.typeOfContent is actually based on URL parameters.
If possible to send JSON data to this handler then how to do that. I am trying to access the handler like this:
Since the calculation I performed gives me -71.77 Volts, I need to match this value to the time that this occurs closest to using my program, and output the time that this occurs at.

If you're curious, this program isn't for homework. It's part of the independent learning on C++ I'm doing for a Master's Thesis; the program will eventually model the APD90 of a ventricular action potential.
I am wanting to be able to add as many different instances of data, while the user has not stated 'n', but then it only ever writes back to the screen the input for the last set of data. Where as I want to display back to the screen all the data that has been entered.
I am very very new to C++. A bit of background. I have been writing in excel vba for large number crunching, and the code is now taking quite a while to run. A friend of mine suggested i start writing in C++, so i read up on it. And downloaded Code:Blocks.
My VBA Code is:
Sub arrayss() Dim NameArray As Variant Dim datarray As Byte Dim DirectionArray As Variant Dim WinArr As Variant
[Code] .....
Ultimately i would like to recode this to C++, but my first and probably silly question is how do i get the data from Excel to use in C++. I was thinking either to put the data in 3 csv files and convert into three Arrays in C++. Or maybe create a library of the data in C++. Ultimately it is speed i am looking for, so before i start recoding i wanted to start with the best way.
The data is like this in excel: (don't know how to create a table)
So the headers would be in one array, the 15's, 30's etc would be in another array and the 1's and 0's and Empty ( i need it to record an empty cell) would be in another array...
I need to perform operations on data from .data file i am able to load the file but how to use the data and perform operations on it. The file had roughly around 200 entries.
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.
I am trying to stream data to a file, and then return to the file to add further data. When I add data the second time, I then want to update the value of the second byte in the whole file. I can't seem to do this!
Here is my sample code:
Code: int a = 1; int b = 2; int c = 3; int d = 4; int e = 5; int f = 6; int g = 7; int x; fstream out1("file.dat", ios::out | ios::binary | ios::trunc);
[code]....
The output I get is "1, 2, 3, 4, 5, 6", but I want to be getting "1, 7, 3, 4, 5, 6", because in "out2", I seekp to the second integar entry, and change it to "7".
I have also tried using ios::ate in the constructor for "out2", but this gives me the out put "4, 7, 6, 6, 6, 6", which is suggesting that when I create my fstream object "in", any seekg commands are relative to the beginning of the "out2" stream, rather than the "out1" stream.
