I am trying to write a program that prints a 2d array to the screen and then compares each row and column to see if there is any pairs of letters. basically something that looks like this:
--------------------------- V T A Y U C B D F W Q Q C R D A L Y M F G O A S S D T I
Number of horizontal pairs: 2 Number of vertical pairs: 3 ---------------------------
so far this is my code below, but i dont know how to approach the comparisons
Code:
#include<stdio.h> #include<stdlib.h> #include<time.h> int main( void )
Here's my code for adding the rows and columns. My problem is that my program displays an incorrect output.
main() { int a[20][20],r,c,y,x,sum=0,rn,cn,cs=0,rs=0; cout<<"Enter number of columns : "; cin>>cn;
[Code] .....
This should be the output Enter number of columns: 4 Enter number of rows: 3 Enter twelve numbers: 9 2 3 4 2 3 1 2 5 6 7 8
The numbers are: 9234 2312 5678 Sum of number 1 column is: 16 Sum of number 2 column is: 11 Sum of number 3 column is: 11 Sum of number 4 column is: 14 Sum of number 1 row is: 18 Sum of number 2 row is: 8 Sum of number 3 row is: 26
You will write a program that uses a multidimensional array having 3 rows and 8 columns and sorts each of the rows using both a bubble sort and a selection sort.
You must declare the array inside of main. You will have a for loop containing the calls to bubbleSort and selectionSort. You need to pass into function bubbleSort and selectionSort the following: 1) each column of the multidimensional array, 2) the size of the column, and 3) a particular row number of the multidimensional array to be used for printing out the "pass" shown on the following pages.
I keep getting an error that the identifier for bubbleSort and selectionSort is not found. (Error C3861)
Also, I feel like I'm missing something in int main() to get it to sort properly.
Code: # include <iostream> using namespace std; int main() { const int SIZE1 = 3; const int SIZE2 = 8; int arr [SIZE1][SIZE2] = { { 105, 102, 107, 103, 106, 100, 104, 101 },
how to make the it all work later...but in the mean time how can i get this to display this? Note it has to be made using as a console program. The "Description" and "Cost/ib" collums will be referenced through use of a header file. all else is done by user input and calculations.
I'm having trouble trying to get my loop program to display multiples of 4 in rows and columns. My objective is to print multiples of 4 that are less than 100 in a 4 by 4 format.
So far when I write the code I get 4 8 12 16 20 .... 96 all on the same line.
This is what I expect the code to look like if done correctly.
I want to swap the value of two rows in matrix among themselves, the index of rows are user defined.
void swapRows(int matrix[M][N], int m, int n, unsigned short R1, unsigned short R2) { for (int i=0; i<m; i++) { for (int j=0; j<n; j++) { //dunno what to put in here
Code: int a[6]={1,3,5,8,10,12}; int b[3]={3,5,9}; int c[6]={0}; if a is equal to ANY of the data in b, then c= a*2 if a isn't equal to any of the data in b, then c=a.
Here is the answer I want
Code: c[6]={1,6,10,8,10,12}
I tried using two for loop, but it isn't correct.....
Code: int a[6]={1,3,5,8,10,12}; int b[3]={3,5,9}; int c[6]={0};
i want to print Largest number from any 5 rows.Th number printed should be any one of the largest in the five rows of 2d arrays.I have created code for largest number in each row but how to pick and print them randomly?.
Code:
#include<conio.h> main( ) { int a,b,c,d,e,x; int arr[] = {a,b,c,d,e}; int Matrix[5][5] ={ /*Initializing array*/ 2,4,3,5,9, 6,8,2,2,10,
How i draw such a thing in .TXT file using file handling. This output must be in columns and rows and in well arranged form.

I have to make a grid 40 X 40 with random numbers 0-9. I have already done this and it prints out great. My problem is I need to be able to choose a row number and output the sum of the number in that row. Here is what I have so far.
#include <iostream> using namespace std; int main(){ int Values[40][40]; int rows, cols;
I wanted to retrieve all rows from database and display in listview using list<string>
con.Open(); MySqlCommand view = new MySqlCommand("Select Cust_ID,Fname,Mname from Customer;", con); MySqlDataReader v1 = view.ExecuteReader(); while (v1.Read()) { for (int i = 0; i < v1.FieldCount; i++){ result.Add(v1["Cust_ID"].ToString());
Basically when I type in different widths and heights for the col and rows, the buttons that make up the width get cut off. Something is messed up but I'm not sure what!
InitializeComponent(); int _col = int.Parse(cols); int _row = int.Parse(rows); int width = groupBox1.Width; int height = groupBox1.Height; int bW = width / _col; int bH = height / _row;
Im using apmatrix and im inputting values into a 4 by 4 matrix and im getting all these errors that have nothing to do with my cpp file so im guessing its apmatrixies fault. Also I put in the cpp and header file of both apmatrix and apvector into my project folder. Heres my code:
error C1189: #error : The C++ Standard Library forbids macroizing keywords. Enable warning C4005 to find the forbidden macro.c:program filesmicrosoft visual studio 11.0vcincludexkeycheck.h2421TheMatrix

I am trying to sort a Report Table by which the user can enter any column or row number and output the results. And also sort by names as well. And from my code
#include "stdafx.h" #include<iostream> #include <string> #include<iomanip> using namespace std; #include <stdlib.h> /* srand, rand */ #include <time.h> /* time */
[Code] .....
I know I need to start somewhere with a void function and put in a selection sort.
I want know if the query returned zero rows or not.
Don't want to use count(*)
sql = "select * from TABLE where employeefirstname = @First order by EmploymentStatusDescription"; using (SqlCommand cmd = new SqlCommand(sql, conn)) { cmd.Parameters.AddWithValue("@First", First); reader = cmd.ExecuteReader(); } while (reader.Read())
I want to be able to keep on adding a row to my datagrid every time i click a button, the row will hold the text of the text box and the combobox in its individual cells, is there a way to do this without inserting a ridiculous amount of code?
I retrieve all the row values from database into text box.But I could not Update it.It shows error message is : The variable name '@value' has already been declared. Variable names must be unique within a query batch or stored procedure. Must declare the scalar variable "@keyValue".
my code is here:
public partial class ECB_ECBConfiguration : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { DataTable dt = ECBDal.GetECBConfiguration(); foreach(DataColumn col in dt.Columns)
I am having a problem with deleting gridview rows. I am populating my gridview by selecting value in a dropdownlist then by clicking the add button, value will be added in my gridview, here is my code:
In my aspx:
<asp:GridView ID="GridView1" runat="server" CssClass="mGrid" EmptyDataText = "There are no records to display"> <Columns> <asp:TemplateField ItemStyle-Width="10"> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="CheckBox1" runat="server"/>
[Code] ....
With the btnRemove codes above, If I clicked it, it'll remove all values in my gridview even the unchecked rows, what I want is that just the checked rows not all. And are there any other simple way of removing rows in a gridview than using checkbox? I am using c# with asp.net.
I'm getting an error when I want t add a file to my dataGridView that I can't add any data because it is databound. I've been working around this but still gives me the same error. heres the snippet of the code:
I have a N queens (actually 8 queens to be specific) program that accepts the numbers in order by row. I need to get it so it accepts the numbers in order by column. At first glance I thought it was just one space different, but it turned out not to be and how to get the one space difference in there. My current code (which I'm aware isn't doing the column accepting right) is:
Code:
#include <iostream> using namespace std; int main() { int board[8]; cout << "Enter the columns containing queens, in order by column: "; for(int i = 0; i < 8; ++i) { cin >> board[i];
[Code]...
What the output should be:
Code:
Enter the rows containing queens, in order by column:
