I have to write a program to display multiplication tables. I have written the following code:
Code:
#include <iostream>
#include <cstdio>
using namespace std;
int main(){
[Code] ....
i need the output to display the product of every whole number from 1-3 in a table format.
this is the code i have so far. i know some brackets are missing but i just pasted the meat of the code. when i run the program i keep getting the number 1 displayed in a straight line going on forever
int multiply1 = 1;
int multiply2 = 1;
while(num1<=3)
{ // num1*num2;
//num1 = 0;
while(num2<=3)
{ Console.WriteLine(multiply1*multiply2);
if(num1>=3)
{ Console.Write();
}
}
num1++;
}
I just want to know the code of the program: Write code to accept matrix as aurgument and display its multiplication matrix which return its multiplication matrix.

I just started Linear Algebra for my programming degree and to full understand everything I want to put it into code and make my own "matrix calculator." I have all the theory but I am having issues keeping the matrix variable and moving it around the class' functions to create it and output it. Once I know I have it saved I think I can get the addition/multiplication to work. Here is the code I have so far:

I have made a Biginteger class that performs multiplication operation according to Karatsuba's algorithm. But it seems that the code is not working perfectly.In the class I have made a function named karatsuba(BigInteger a1, BigInteger b1)that performs the Multilplication operation. There might be problems in this function as I have tried to store the original digits(neglecting the leading zeros) of the two big integer values into two integers or there might be problems in somewhere else. corrected version of this function? My code is given below:
#include <stdio.h>

I have a program matrix multiplication but it work not for big arrays. n should be bis 200.

Write a program that prints a multiplication table using nested loops. In main ask the user for the smallest column number , the largest column number and the size of the increment. Ask the user for the same information for the row values.
In the example the column values entered are: 5, 15 and 2 and the row values 3, 6 and 1.
Given those numbers you would generate the following table.
Multiplication Table
| 5 7 9 11 13 15 ___|___________________________________ | 3 |
15 21 27 33 39 45 4 | 20 28 36 44 52 60 5 | 25 35 45 55 65 75 6 | 30 42 54 66 78 90
Print the 24 values with the grey background. The other numbers show the values to be multiplied.
Code:
#include<stdio.h>
main() {
int a,b,c,d,e,f;
int i,j,total;
printf("Please enter smallest column number: ");
scanf("%i",&a);
printf("

Challenge:
As an added challenge try to print out the column
headings (5 7 9 11 13 15) and the row headings (3 4 5 6)

View 1 Replies View RelatedI need to run some basic statistics on about ~150 tables that are currently in dBase format.

View 4 Replies View RelatedIn my code I have lots of structures. I try to make tables of structures and then get access to elements of the structures to use them all along my code: here is an example to clarify things
typedef struct {
Fabric **closfabric;
}Network;
Net is part of another structure called Switch and Fabric itself is a composed structure. I have done the following
aSwitch->net.closfabric = (Fabric **)malloc(3* sizeof(Fabric *));
aSwitch->net.closfabric[0] = (Fabric *)malloc(m * sizeof(Fabric ));
aSwitch->net.closfabric[1] = (Fabric *)malloc(k * sizeof(Fabric ));
aSwitch->net.closfabric[2] = (Fabric *)malloc(m * sizeof(Fabric ));
The compilation returns a segmentation fault because aSwitch->net.closfabric is NULL (0) .
Surprisingly, in other codes the same analogy of using tables made of double pointers works perfectly with no problems and I have no problem of core dumped and NULL pointers.
Why am I getting this problem. It is the case whenever I try to use large dimension tables (tab *** struct for example)...
i'm trying to update multiple table values with same column using one query.
Here's what i've tried so far:
mySql.CommandText = "Update tbl_employees,tbl_emp_additional_info,tbl_allocated_deductions,tbl_benefits,
tbl_cashadvances,tbl_deduction_history,"+
"tbl_dtr,tbl_empabsences,tbl_empstatus,tbl_otherdeductions

"set tbl_employees.emp_id=@newemp_id,tbl_emp_additional_info.emp_id=@newemp_id,tbl_allocated_deductions.

I've also tried removing all the other "and" operators but still no luck.It doesn't throw in exception yet it doesn't update my tables column values.

Currently I have to manually look up values on several different tables in different locations. I have 8 or 10 tables with 100 to 500 parts.
I would like to write a program so if I enter a value it will return the corresponding correct answers from the tables.
If I entered 2.5 for a value it would return the following three items from the tables since they all meet the requirement.
Table 2
Part min max
235 2.4 2.9
Table 6
Part min max
589 2.3 2.5
Table 7
Part min max
12 2.3 2.7
What would the best method be for setting up and accessing tables like this? Is C++ good at representing something like this or should I be looking at a different language?
i have stuck in a join and i cant figure out where the problem is, i have those tables
public class Themes
{
[PrimaryKey, AutoIncrement]
public int Id { get; set; }
[Code].....
The problem is that the data table doesn't show at all. Here is the code:
<%@ Page Title="" Language="C#" MasterPageFile="~/LB/MasterPage.master" AutoEventWireup="true" CodeFile="InsertedInfo.aspx.cs" Inherits="LB_InsertedInfo" %>

Basically I have a few tables in my Database.
So I have one table that is like so:
Item_ID, Name, Parent ID.
1 , jeff , 5
and another table like this:
Parent_ID, parent_Name
5,jackson
What I would like to happen, when I run my code is that I'll get the following
Item_ID, Name, parent_Name
1 , jeff , jackson
DataSet DS = new DataSet();
if (this.OpenConnection() == true) {
mySqlDataAdapter = new MySqlDataAdapter("select Item_ID, NAME, Parent_ID from table1, table2", connection);
mySqlDataAdapter.Fill(DS);
dataGridView1.DataSource = DS.Tables[0];
//close connection
this.CloseConnection();
}
So this spit out parent ID = 5.
I've not worked with Dataset before and I was just wondering what is the best approach? Can this be done via a SQL command or will I have to replace the value(5) with the string(jackson) using a large IF loop to search and replace.
I'm trying ultimately to do a radix sort. I'm going with the implementation using two tables. One will initially hold the unsorted values then hold the partially sorted values thereafter. The other will be an array of linked lists which will be where the radix sort is done. Here is my code thus far:
Main
#include <iostream>
#include <fstream>
#include "radix.h"
#include "radix.cpp"
using namespace std ;
int main ( int argc , char * argv [ ] ) {
ifstream input ( argv [ 1 ] ) ;
[Code] ....
It appears to be crashing during void insert_into_sorted ( int to_insert , int place ) ; and I'm not sure why.
I'm having a bit of trouble with something. What I'm trying to do is create a new Access table by combining other already existing Tables.
For instance, let's consider Table1 (with columns A, B and C), Table2 (with columns A, D and E) and Table3 (with columns A, F and G), where Table1.A = Table2.A = Table3.A.
From these, I want to create a new table TableResult, with columns A, B, C, D, E, F and G, with all the data contained in them. There's one catch: I want the code to get the names of the other columns, apart from column A.
I've thought about using Union, but I need to actually create a new table by combining the previous tables.
i have 2 tables with primary and foreign key
Customer Details
EID - Primary Key
PurchaseDetails

This one works fine and it's a great commented code to understand even for beginners like myself, but it only works with one table per sheet. Once I add second table in sheet, it throws an error that something is wrong in one of the columns in my spreadsheet: It says: " Error occurs! The error message is: Cannot find column 4. "
Basically, I have this type of tables in my spreadsheet:
So I want that my program would export those two tables in a single .XML file (just read them both). And those two tables should be separated in two XML childs: the upper one should be Order-Header and the lower one - Line-Items, like this:
<ROOT>
<Order-Header>
.....
</Order-Header>
<Line-Items>
.....
</Line-Items>
</ROOT>

[Code] ....
I copied all the code because I think it is the easier way to spot where to change it, to read those two tables in one spreadsheet and export them both in one XML file. How could I achieve this kind of functionality.
I need to show in a comboBox thats shows infor from Entity framework but i need to select a specific colum in the tables..
All in C# visual studio xaml form
So I created a var but i get and output: name of programe.NLHEntities
using (var context = new NLHEntities()) {
var blog = context.EtagesChambres
.Where(b => b.TypeChanbre == "Prive")
.FirstOrDefault();
textBox2Type.Text = Convert.ToString(blog);// i put a text box to see what the output would be..
}
