I have this code it sums the rows now I need it so it would sum all the columns in the output and put it in row 8 of the outcome. How would I go about doing that?
Code:
#include Code: "stdio.h"
#include "stdafx.h"
int main(void) {
int number[8][7];
}
[code]....
I have this code down except I'm very confused how to make the output come out in 3 columns.
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
int i, j, n, flag = 0, prime_number = 0, temp;
cout << "Enter first prime numbers that will be used or -1 to end:" << endl;
cin >> n;
[Code]...
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20
Twin Prime Number : (3,5)
Twin Prime Number : (5,7)
Twin Prime Number : (11,13)
Twin Prime Number : (17,19)
But what I want is: 1. {3;5} 2.{5,7} 3.{11,13} 4. {17,19}
I am trying to make a table class that will be able to have multiple columns of data. I want it to have something to hold data (I was using a 2D vector for only one data type) in it, somewhat like a pair, but for any number of data types. The class is a template to make it generalized.
I have looked a little at variadic templates, but I don't know how to declare the vectors for each data types then.

4. {17,19}
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.
View 2 Replies View RelatedI'm working with arrays and I get them column by column and need to print them. I as there a way to print in columns?
For example: I produce an array of A, B and C from a loop and then need to print them in one column and the go to the next column ....
so in the end I shall have an output like this:
A E
B F
C G
D h
... ...
My arrays are too long (over 50K) so I cant just store the arrays and then print them. I need to produce each column array, print them and delete it and go to the next column.
I have a basic question regarding 2d vectors. The following code makes a 2d vector and fills it with a matrix of integers. The vector tempVector3 gets added as a new row to the matrix. But what if I wanted to add the tempVector3 as a new column instead. How would this be done in the simplest way?
#include<iostream>
#include<vector>
int main(){
std::vector<std::vector<int>> numbers;
std::vector<int> tempVector1;
tempVector1.push_back(2);

I have a file that can range from 100 rows to 10000+ that is comma delimited with 8 columns. The first 32 rows (also comma delimited) will always be ignored (geographical header information). I will be wanting the data from column2 and column3.
For this I believe I would need (2) For Loops as such:
for(i=0;i<2;++i) {
getline("do something here");
}
and
for (i=0;i<3;++i) {
getline("do something here")
}
Also would using a vector or array with dynamic storage be the better way to tackle this problem? Where to start from after accessing the file.
I am trying to add labels to the data. I have data in a file divided by space:
1 2 3 4 5 6
7 8 9 10 11 12
I need it to look like this:
label_1: 1 2 3 4 5
label_2: 6
label_1: 7 8 9 10 11
label_2: 12
How can this be done?
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.
4 8 12 16
20 24 28 32
36 40 44 48
52 56 60 64
68 72 76 80
84 88 92 96
This is code that I have so far.

Ok so I'm working with a windows form in C# and sql server database. I'm trying to do something like what is in the image below using a datagridview. My question is how do I 1) ensure only 1 checkbox is checked per row 2) do math that 'links' a checkbox column with another column, and add the totals. I understand that asp.net and web forms would be easier but we have not reached that point in the course yet. Would this be on the right track:
foreach (DataGridViewRow row in dataGridView.Rows)
{
if ((bool)(row.Cells["Checkbox"]).Value || (CheckState)row.Cells["Checkbox"].Value == CheckState.Checked)
{
// Do something
}
}
Attached image(s)
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20
Twin Prime Number : (3,5)
Twin Prime Number : (5,7)
Twin Prime Number : (11,13)
Twin Prime Number : (17,19)
But what I want is:
1. {3;5} 2.{5,7} 3.{11,13}
4. {17,19}
else if (i - prime_number == 2)
{
cout << "{" << prime_number << ";" << i << "}" << endl << endl;
prime_number = i;
}
So I made a text file which goes like this
word word word word
word word word word word word word
word word word word word
word word word word
(word is actually word I just didnt type them)
Now i figured out how to get the rows to work
#include <iostream>
#include <fstream>
#include <istream>
#include <stdio.h>
int main()
{
FILE* fp;
int countLines = 1;
int i;
[Code]...
I cant figure out column to work... Is it the same method cause im getting confused a lot!
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.

How can I read just the first column of this from a text file?
ORG 100
LOAD X
ADD Y
STORE Z
HALT
X, DEC 49
Y, DEC -80

I have
while (! sourceCode.eof() )
{
getline(sourceCode,symbolValue,'

sourceCode >> symbolValue >> codeWord >> value;
symbolTable << symbolValue << endl;

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
This code is show all the composite numbers1 to 100. how can i add a limit of 5 column in this sample program??

The assignment is to plot the functions, by implementing a function having the following prototype:
void plotPoint(double y);
This function should print a single "*" symbol, in a position determined by the value of y, and then a newline. The position of the * symbol can span over 80 columns: each column should represent a delta of length 0.1 in the value of y, and the zero should be placed on the 40-th column.
For example:
• placePoint(0) should print the * symbol on the 40th column
• placePoint(0.1) should print the * symbol on the 41st column
• placePoint(1) should print the * symbol on the 50th column
• placePoint(-1) should print the * symbol on the 30th column
Here is what I have so far:
#include <iostream>
#include <cmath>
int a;
int b;
int x;
int y;
int Func1(double a, double b )/>
[Code] ....
I'm lost now as to where to go to plot. I know that depending on the option chosen I call the corresponding function to return a value for y which is just then plugged into a function to plot it on columns of y.
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:

//cout, standard output
// <<, stream insertion operator

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

using namespace std;
#include <stdlib.h> /* srand, rand */
#include <time.h> /* time */

I know I need to start somewhere with a void function and put in a selection sort.
i'm using DataGridView and the sorting operation,by clicking the column header, is working fine , but when i add the drag and drop operation it doesn't respond . i think it can be fixed by disabling the drag and drop for the headers, but i just couldn't find a way to do that.
View 7 Replies View RelatedI 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.

The program need to find mean of elements in columns which are divided by 3. And to print which colmn has the greater mean
Example
For matrix:
7 9 5
17 15 30
29 34 60
Program print: 0 12 45. The greater mean: 3 column.
I wrote this code and it prints 0 12 45 idk how to find which column has greater mean?
Code:
#include <stdio.h>
#define max 50
int main()
{int n,m,i,j,k,d,br=0,suma;
int a[max][max];
int b[max][max];
printf("Kolku redici i kolku koloni da imat matricite: ");
scanf("%d %d ", &n,&m);

I'm not sure why Im getting a wrong Sum. of the Columns.
Write a method that returns the sum of all the elements in a specific column in a matrix using the following header:
double sumColumn(const double m[] [SIZE], int rowSize, int columnIndex)
Write a test program that reads a 3-by-4 matrix and displays the sum of each column. here is a sample run:
Enter a 3-by-4 matrix row by row:
1.5 2 3 4
5.5 6 7 8
9.5 1 3 1
Sum of the elements at column 0 is 16.5
Sum of the elements at column 1 is 9.0
Sum of the elements at column 2 is 13.0
Sum of the elements at column 3 is 13.0
#include <iostream>
using namespace std;
const int SIZE = 4;
int rowSize=3;

So in my winform form, I have a table layout panel and I attach Controls on the row. I make some control span multiple columns... But since I use transparent for the background of the layout panel, it show the border between 2 cells that I span.. Like this:
How do I erase the border in the middle of IDLabel?
