I'm trying to read values from a file to store them in an array in C++ and then output the values in a table format for everyday of the month: morning, noon, evening and night. My text file looks something like this:
38
210
14
3
214
222
82
176
225

#include <iostream>

How can I Figure out and store the sum of EACH COLUMN in the 2D array values in a 1D array? And to the same for the average?

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>
#include <string>
using namespace std;

So I have this text file that I am trying to read from and store the values of each line in multiple variables.
Let's say my text file contains
AXSYZ3482 Tom 100 112
and my code below here works fine when the lines in the text file is separated by spaces.
while (fscanf(fp, "%s %s %d %d
", userID, name, &startLoc, &endLoc) != EOF) {
printf("%s %s %d %d
", userID, name, startLoc, endLoc);
}
But let's say my file was to look like this instead.
AXSYZ3482:Tom:100:112
But if i try this below...
while (fscanf(fp, "%s:%s:%d:%d
", userID, name, &startLoc, &endLoc) != EOF) {
printf("%s %s %d %d
", userID, name, startLoc, endLoc);
}
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth. How I can accomplish this?
I have a file this is made by 7 column. I want to separated them as columns and stores as arrays.lines should be 0 ,1 ,2 ,3 .. and arrays are the name 0,1,2,3,.. my program is not opening and giving me mistakes such:,
read_from_file
ead_from_file
eading_from_file.cpp(26): error C2784: 'std::basic_istream<_Elem,_Traits> &std::operator >>(std::basic_istream<_Elem,_Traits> &,std::basic_string<_Elem,_Traits,_Alloc> &)' : could not deduce template argument for 'std::basic_istream<_Elem,_Traits> &' from 'std::basic_ostream<_Elem,_Traits>'
And my code is
#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>
#include <string>
using namespace std;

int i;

That;s what i have so far: problem: the output data is not correct.

read a text file and store the file contents into a 2D array?

int array[ROWS][COLS];

When i run the program and try and display the array, it doesn't work.
I am trying to store the contents of a text file into a char array. However the function i am using ifstream member function get(); seems to stop working when fed with certain characters. Is there another solution besides the get() function that will accept all types of characters from files?
char text[1000];
for (int i = 0; i <= textlen; ++i)
{
text[i] = text_in.get();
}
I'm trying to read the data from a file i/o and put them into an array of structs. But when I run the program, it gives me a bunch of "garbage" as an output. my code and see

I am trying to store a large text file into an array so I can count the number of characters.
View 2 Replies View RelatedI am working on a text based RPG. As with most RPGs the character has attributes that grant modifiers. Lets take strength for instance. Suppose the character can have a strength score that ranges from 1 to 10. Based on strength the modifiers could be like the following:
Strength = 1 grants +1 to hit and +1 damage
Strength = 2 grants +1 to hit and +2 damage
Strength = 3 grants +2 to hit and +3 damage
I want to set these values at design time and be able to retrieve the modifiers based on the strength value from multiple places in my program.
What is the best method of designing this. I looked around online and saw references to Lists with Tuples and Dictionaries with Tuples but these did not seem to be a very efficient way of handling the scenario above.
I just wanted to know how to store big numbers (like more than 20 digit values) in a variable?
For those type of big values, whether float variable is good or int variable is good?
And finally, all these challenges i am facing in the process of coding for an application which contains calculator and it should give the accurate results as our windows pc calculator.
I can`t seem to store multiple values into my vector when a user keys in an input. Lets say a user inputs 1,2 as the first set and later keys in 3,4.
My vector gets overridden by 3 and 4. I'm trying to pass these values into a function to store them into a vector and use them in the function.
Below is my code snippet
int reconstructSecret(int x, int y) {
int getX,getY;
getX=x;
getY=y;

I serialize a XML file, and i have this values here:
public class ServiceConfig {
public List<DatabaseDescriptor> Databases { get; set; }
} public class DatabaseDescriptor {
[XmlElement("Name")]
[Code] ....
I have a form1 which is a datagrid view and get's updated like this:
dataGridView1.DataSource = xmlData.Databases;
Now i have a button: get tables, and it opens up form 2, there it's supposed to appear all the tables of the selected Database, when i click on the row i get the database name so i get all the list of Tables from
DatabaseDescriptor
where
DatabaseDescriptor.Name == name
(I get this when i select the row)
But then on the 2nd form, i also have 2 textbox so i add a new table, i add the tablename and id. the new value should appear in the datagridview of the tables, and when i close it and reopen it, it should be there. Maybe i should concatenate first the values or something, how do i do?

I want to store values permanently in a variable. The same variable should be able to be edited and saved by user, and whatever it is I need the value of the variable from the last time I modified it, like a database. database because i need this to set my connection string of the database.
View 1 Replies View RelatedMy problem is that I need to take a csv or excel file with tens of thousands of datapoints, write all points in a section of column to an array, perform calculations on them, and then write it back into another column.
I've been looking all over the internet for ways to do this easily. So far I have not found anything that I can follow and implement.Some codes have been slightly useful, but they aren't commented in a way I can understand. How to write code to take, for instance, lines from column b between 500-1000, write them to an array, and write another array 500 characters in column c. If that code could be commented, I have tried a few different techniques (counting commas), but haven't gotten anything to work.
i need to display the current time and date in my program and use variable to store each of the time values like
a = 10
b = 29
c = 31
printf(``%d : %d : %d``, a,b,c);
which then give the output as - 10:29:31

I have a datatable which comprises values from 1st January to march, something like this:
DataTable datatable = new DataTable("Employee");
datatable.Columns.Add("Date", typeof(string));
datatable.Columns.Add("Employee", typeof(string));
datatable.Columns.Add("Job1", typeof(double));
datatable.Columns.Add("Job2", typeof(double));
datatable.Rows.Add(new Object[] { "1/4/2013", "A", 1.3, 2 });

The result should look like this for Job1:
Employee 1/7-1/13 1/14-1/20 1/21-1/27 1/28-2/3 and so on...
A sum of values for this 7 days

I had to change my array initialization to one with a star in front of it:
char a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
to:
char *a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
I also changed my 2nd array to one with a star in front of it: char *a2[20];
What does this mean exactly? Putting a star in front of an array?
Also, I am now getting an "unhandled exception" when I try to get input for my 2nd array:

I am attempting to read values from a file into a 2d array temp[31][2] (31 rows, 3 columns).I only want the values from the file to be read into the first two columns.I believe I am accomplishing that but when I go to print the array, I expect the first two columns to have the file data and the third column to have all zeros. The third column, however is printing such that the value is the next row/first column.
I'm not sure for instance why on the bottom loop for line 1 it doesn't print:
temp[0][0] temp[0][1] temp[0][2] 20 49 0 It instead prints: 20 49 1
Code:
#include <stdio.h> Code: #include <math.h>
FILE *inptr;
int main() {
int temp[31][2] = {0}, tempavg[31][2] = {0};
int i, j, k, sum;
