How can I obtain the length of an array that has been sent throughout a function. In the following code, I obtain "2" as output, while I was expecting "5".
I am trying to use fscanf to obtain a set of 14 or so strings per line, in a line where there are around 80 or so different sets of strings. I only need the first 14 and whenever I call scan f it starts at column 209 as opposed to column 1 where it should. Here's a sample of the code:
FILE *d; d=fopen("t.dat","rb"); where a, n are all strings. fscanf(d,"%s %s %s %s %s %s %s %s %s %s %s %s %s %s",&a,&b,&c,..(etc)..,&n);
I was just reviewing some code, and my eye fell on a bit of regex that's intended to parse a date/time stamp into a date and time.
The timestamp uses shorted month names. The regex had all the possible month names to match the entire pattern. If it does, it went through a 2Nd loop to convert the month name into a 1 to 12 numeric value...
This made me wonder, since the regex is already doing the work to verify the alternation, can't it at the same time tell me which of the possible alternations it matched and use that to calculate the numeric value. So basically
Code: std::regex reMonth("Some more regex stuff here (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)."); CString strTest("Some more regex stuff here Aug."); std::cmatch res; if (std::regex_match(strTest.GetString(), res, reMonth)) { //int iMonthNum = res[1].something(); // some code here that returns 8 for Aug. }
Or is there really no other way out than doing a 2nd level verification to figure out the actual month number. (The real regex is a bit more complex than this).
I'm using SQLBulkOperations to insert rows in bulk. I'm using SQLBindCol to bind the columns before SQLBulkOperations().
But how do I obtain the Identities? The bound buffer for the Identity column does not get filled after SQLBulkOperations()
At first I tried to use Bookmarks (column 0), but it seems that that is some other value (thought it would be filled with identities). But now I thought it must be that the bound buffer for the Identity column itself must be updated, but it's not happening. Maybe I need to do something extra?
I have to obtain a check number from a datafile and then also get company information also from a datafile.
So my first question is about the:
Code: char outputFilename[]= "out.list"
Is this the name of the output file I'm going to write to? And also the file has to be created before being used...is that line of code creating the file or do i have to create it in notepad?
I am facing a problem which i could not obtain the total numbers which is greater than the average value. For example:
#include <iostream> using namespace std; int main (){ int size , count; double no, max, min ,total, sum , average;
[Code] ....
In this case im able to compute the average of the numbers but when it comes to capture the total of numbers which is greater than the average value, how to compile the code , because the average number is only been compute once all the value capture by the input of user is sum up.
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] ...
// Here is my code for displaying the data from the text file into a 2d array and height next to it, but I am not able to diaplay the height from 60 to 76 next to the row of the 2d array, as shown in the table below. This is my program:
Recently the health authorities have listed a new way to calculate the body mass index (BMI) of an individual. Values of 20 – 24 are classified as normal, 25-29 as overweight, and 30-34 as heavy.
The table below is a portion of a typical BMI table.
Been trying to configure the GridView to display ony 4 rows of data at a time. I thought it wasn't working because I forgot to set AllowPaging to True, but after I did that, I just get the error of
The data source does not support server-side data paging.
Source Error: Line 66: titlesGridView.DataBind(); // displays query results
Here is my Books.aspx.cs code:
// Fig. 29.11: Books.aspx.cs // Code-behind file for the password-protected Books page. using System; using System.Data.Entity; using System.Linq; namespace Bug2Bug.ProtectedContent { public partial class Books : System.Web.UI.Page {
[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.
Here is my program so far: int main() { std::ifstream inFile; inFile.open("AP.txt"); ofstream results_file ("maxvaluewithinput.txt"); float TimeAtdVMax = 0; float VoltsAtdVmax = 0;
[Code]...
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.
developing an algorithm with use of minimum system resources. I have an embedded board with sends data through rs232 port to system.
the moment i give the command it starts transmiting data to my pc(buffer array) Now the first 317 bytes are read as strings and i am able to get that read successfully.
The rest of the data is to be read in int form.i.e 2 bytes(short int) short quick way to read int data without much manipulation(which may cause loss of data as baudrate is very high).
Here is what i have going so far: Code: ///Reading Data // while(rzBuff[0] != ' ') for(i=0;i<=318;i++)
