C++ :: Print Out All Input Values

Mar 16, 2013

I have a problem with how to print out all the numbers that the user enters the code looks like this so far:

Code:
#include <iostream>
using namespace std;
int main()

[Code] ....

I want the program to print out all the numbers that the user has entered after the program have said the higest and lowest number is ?. But I do not know how to do this I thought it could be something like this:

Code:
cout << input[0];
//or
cout << input[i];
/*

Because i is the number of how many enters of numbers the user can do*/ But that was totally wrong tried to do another "for loop" in the first for loop but that was meaningless because it can't change anything in the first "for loop".

C :: Print Values Of Array By Popularity

Jan 11, 2014

Given an array with integer values in the range [0, 100], print the values by popularity (number of time it appears in the array).

example: array: 60, 60, 70, 80, 80, 80, 80, 100;

output: 80 80 80 60 60 70 100.

complexity restriction: should be linear.cant use advance data structure like lists or hashmaps, only arrays. structs are not allowed.

my idea: to build counter array of buckets of size 101, and count each value.then i need to sort the counter array(its still linear), but how i can keep track that the value of 80 appeared 3 time?I mean i need to sort the values of the counter with the indexes as well.

C :: Possible To Print Float Values Without Decimal Point?

Apr 8, 2013

I was going through the exercises in one C programming ebook.There is this question which asks me to print a float variable in fixed decimal notation, field size of 6, right-justified, no digits after decimal point.I got printf("%6f", x );

x = float variable.

But the above code prints numbers after the decimal point, so I changed it to %d. But %d doesn't work with float variables..

C# :: Populate Datagrid In WPF

Apr 3, 2015

I am trying to get a datagrid working in my program with populating a simple set of data. Which i can then expand on and bring in data from a database.

But even this little simple test datagrid does not seems to be working.

XAML Code

<DataGrid Grid.Row="6" Grid.Column="0" Grid.ColumnSpan="2" Margin="10" Name="DataGrid_1" ItemsSource="{Binding DataGridData}"></DataGrid>
<Button Grid.Row="6" Grid.Column="2" Margin="10" FontSize="12" Command="{Binding Path=GetDataGridData_Command}">Get Data</Button>

C# :: WPF Cascading DataContext Like With DataGrid?

Dec 15, 2014

I'm trying to create custom WPF control, similar to DataGrid. DataGrid was great as a base class for a different custom control I needed, because I could do something like this:

<shared:MyDataGrid ItemsSource="{Binding Persons}" >
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Name}" Width="4*" />
<DataGridTextColumn Binding="{Binding Phone}" Width="3*" />
<DataGridTextColumn Binding="{Binding Email}" Width="3*" />
</DataGrid.Columns>
</shared:MyDataGrid>

where Person class would be like this:

public class Person
{
public string Name {get; set;}
public string Phone {get; set;}
public string Email {get; set;}
}

... and I can reuse it elsewhere with collections of different type, binding its properties to columns of different width and style.

What I need now is something similar, but differs in a way, that DataGrid is no longer good fit for the base class.

What I'm interested in is: how does DataGrid "tell" the columns in Columns collection, to have the type of ItemsSource bound collection as a DataContext? How does the Name property of Person class become available to the column in DataGrid.Columns?

C# :: Read SQL Table To Datagrid

Feb 9, 2014

I have been struggling to implement a method for reading data from SQL server to my C# program. In the C# program I prepared a DataGrid (not a DataGridView) for the data to be shown in it using a button "Load Table". Now I just want to read a table which has 4 different columns which I also added to the DataGrid.

I have a DataAccessDB class and this is the code for establishing a connection:

const string DB_CONNECTION = @"It is known to me";
SqlConnection con;
SqlCommand cmd;
Controller myController;

Then, there is a code to reference controller:

public DataAccessDB(Controller refController) {
con = new SqlConnection(DB_CONNECTION);
cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = CommandType.StoredProcedure;
myController = refController;
}

And this is the code for a List which I am going to use for filling the data to a DataGrid:

public List<ProductionStock> GetProductionStockFromDB() {
int productionStockId, amount;
decimal price;
string name, descript;

[code]....

And now the main part - how to read the data when I press a LoadTable button. The point here is that I already defined connection strings here as you can see, and in the method itself I guess I should not repeat it. The tutorials I have seen they do it everything in that one button.

Mar 30, 2014

i have the following code

protected void Page_Load(object sender, EventArgs e)
{
List<Product> Products = DbConnectivity.LoadProduct();
updateTable(Products);

[Code].....

the code works and produce a table and fills the grid, what im trying to do is get this information into a DataGrid, so i can get rows selected by user. ive tried many ways ie convert the list into a datatable and display but produces errors, ive done the following,

pageLoad....{
FillDataGrid();
DataGridProduct1.DataBind();
}

[Code].....

this populates, but couldnt seperate the SQL connection apart, and it makes no use of the class product

C# :: Populate Data In Datagrid?

Mar 29, 2014

im trying to populate a datagrid, i have a datbase class

public static List<Product> LoadProduct()
{
....................
}

i have a product class

gettor & settors
public Product(int id, string Name, double Price, int Quantity)
{
productId = id;
productName = Name;
productUnitPrice = Price;
productQuantity = Quantity;
}

ive added the HTML code to set up the datagrid, which i can see via design tab, but filling it up is harder.

i uderstand it needs a

protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
sqlDataAdapter1.Fill();// where it require a dataset or datatable
DataGridProduct.DataBind();

as it requires a datatable i converted the list to a datatable when i run it it says null, im not sure where im going wrong, i noe the list works as i tried populating on a table.

public static DataTable ToDataTable<T>(List<T> items)
{
}

C# :: Datagrid Not Updating Styling After Refresh

May 21, 2014

I have a datagrid, which has a column called Status. In the database, the field is a text field that can have the values up, down, or danger.

I needed to display the status as a "light" as per client request, so I have a StatusToImageConverter class that receives the status, and returns the proper image to display in the datagrid column. Works fine.

Now the issue I am having... I have a combo box above the datagrid for the user to filter the results if desired. The filtering works fine, but the newly displayed devices do not have their status light. In the Status column, nothing appears after the user filters. I think it may have to do with the fact that I am not re-initializing the datagrid, but just refreshing it? That's just my educated guess.

XAML:
In the UserControl Resources:

<local:StatusToImageConverter x:Key="ImageConverter" />
In the DataGrid Control:
<DataGridTemplateColumn Header="Status" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>

[Code].....

C Sharp :: How To Bind WPF Datagrid Radio-button Column To Entities Class

May 7, 2012

In my WPF application I created a LINQ to SQL entities class. Then I created a partial class and there add code to my entity class. Below is the code of it:

namespace Mynamespace {
    partial class rts_index {
        #region Fields  
        /// <summary>
        /// Status:
        /// "Selected" - true, "Unselected" - false.
        /// </summary>
        private bool _is_selected;

[code]....

Then I executed LINQ to SQL. Works perfectly well. Then I bound WPF Datagrid radiobutton column to is_selected property of the partial class. Below is XAML code:

.
.
.
<Window.Resources>
<CollectionViewSource x:Key="rts_indexViewSource" d:DesignSource="{d:DesignInstance my:rts_index, CreateList=True}" />
</Window.Resources>

[code]....

And here I have the problem. When I'm changing the radiobutton status from Unchecked to Checked it doesn't change the value of is_selected property from false to true in the partial class. I don't know why.

C :: Print Correct Normalized Value / Average And Values Above Average

Nov 14, 2013

I must write a function that has a one dimensional double array and the number of values in the array as its arguments. Normalize the values. I must also print the maximum, minimum, average and numbers of values above the average in the array.

The equation that computes the normalized value from a value x is:

Normalized x= (x-min(array))/(max(array)-min(array))

My code does not print the correct normalized value, average and values above average.

Code:
#include <stdio.h>
int findMax( double array1[], int num_elements) // This function computes the maximum value of the array
{
int i, max=-32000;
for (i=0; i<num_elements; i++)

C :: Print Values Of Array From Function By Passing Array?

Nov 1, 2014

I wanted to print the values of a array from a function by passing the array as well as the number of elements to be read. For a single dimensional array, this is how i have written it. It's pretty straight forward. I want to read 5 elements from the 5th element in the array.

Code:
#include<stdio.h>
void display(int array[],int size) {
int i;

[Code]....

With this code I want to print the five elements from the element present in [0][4].

But shows an error that

Code:
D:BennetCodeblocks CLearning CSingleDimentionalArray.c||In function 'main':|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|18|warning: passing argument 1 of 'display' from incompatible pointer type [enabled by default]|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|2|note: expected 'int (*)[10]' but argument is of type 'int *'|
||=== Build finished: 0 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|

I know when you pass a array as an argument it gets decomposed into a pointer, but with a multi-dimensional array this is not the case. how this works for mult- dimensional array's?

C/C++ :: Final Output Needs To Print Initial And Final Values

Jan 28, 2015

I have a program that is reading six characters from a text file, swapping every other character(ABCD would read BADC), and then adjusting their value based on a user's adjusted value input. If the adjusted value is 5 then letter A becomes F.

The final output line should print the initial six characters followed by the final six characters after the swap and encrypt adjustment.

I can only manage to print the final characters. Am I far off thinking I need to use pointers to point to the original character values?

One more thing: instructor wants us to complete this project as simply as possible meaning without the use of arrays, loops, switch statements, etc.

#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main() {
//declarations
char c1,
