I'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.
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.
Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code: #include<stdio.h> #include<stdlib.h> #include<math.h> int main () {
# include <conio.h> # include <stdio.h> # include <stdlib.h> # include <string.h>

I tired changing the conditions in the for loops, but then I end up entering information multiple times and I want that to be the user's option. Do I have to change the for loops or something else? I've tried everything to get what I want but nothing works. When I print the receipt, only the last food Item that I entered prints.
I have 3 arrays (even, odd and negative), they are all different sizes, but they maximum elements they can have is 50. How do I write them to a file in this format
EVEN ODD NEGATIVE 2 3 -2 4 5 -4 6 7 -9
Code:
size = 50; //they dont all 50, its just that array cant be bigger than 50 for (int i =0; i < size; i++) { cout <<setw(5); if (even[i] != 0) { myfile << eList[i]; myfile << endl;
I have a problem in dealing with dynamic arrays. I have initialized the objects and now i want to print them.
Code: // main char* namesList[] = {"Brad Shaw","Aimen Adams","Sal Dimitry","Cristi Anreaz","Poala James"}; int idList[]={232,444,135,52,134}; Team t1( namesList,idList,5,"waqas"); t1.Print_team(); My class Team looks something like this:

The print function does not work. I have to implement the print function without taking any parameters.. How should i do that ?
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]; }
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; [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)
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 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:
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'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.
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)
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; }
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.

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
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:

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.
