C++ :: Mode In 2-D Array
May 2, 2014
I have to find mean,mode and median of a 2-D array :
2 5 2 5 9 5 8 3 6 10
8 1 10 10 7 1 4 4 3 8
4 3 1 2 4 10 3 9 8 5
6 10 8 3 6 10 5 1 2 5
2 2 9 2 5 5 1 1 7 5
7 9 9 2 1 5 2 2 2 4
3 6 1 9 3 4 10 7 4 6
7 10 4 6 2 10 10 8 7 6
7 1 3 6 2 4 6 7 8 9
8 5 9 2 3 2 1 5 1 8
I coded for mean but stuck for mode.
Code:
// Assign4_Q2.cpp : Defines the entry point for the console application.//
#include "stdafx.h"
#include<iostream>
#include<iomanip>
#include<conio.h>
using namespace std;
[Code] ......

I've been trying for over an hour to think of the logic to find the mode of an array.I left out code for initializing the arrays, but all the values in the array are between 0-9. Check out my code below.
Code:
int mode( int array[], int size ) {
int i;
int count;
int max = 0;
int num = 0;
int mode;
[code]....

How do you find a mode in array? This is what i got so far. I put this after i sort the array
for (int index = 0; index < size2; index ++) {
//count[mode[index] - 1]++;
if (mode[index] == mode[index + 1]) // compare the first to sec array {
again++;
cout <<"This is number " << again << endl;
}
}

I've been working to make program to find the mode of sorted array. But the program didn't return the results correctly. Here is the code:
#include <iostream>
using namespace std;
int main () {
cout<<"Enter the size"<<endl;
int size;
cin>>size;
int data [size];

My code seems to find the mode of the array I input sometimes. Sometimes it gives me the wrong number or multiple numbers. It just all depends on what is number is inputted into the array. I don't know what the problem is. I tried looking online and editing many times and can't find the answer. Maybe I'm overlooking something or doing something wrong. Here's my code.
#include <stdio.h>
void readArray(int arr[], int length)
{
printf("Enter data:
");
[Code].....
Maximum: 15
Mode: 2
As you can see the mode is clearly not 2 and I do not know why.

I'm writing a program that calculates the mode, mean and median of an array of integers. I've done the mean and median but i can't figure out mode.
I have to find the number of modes.
Ex array of integers: 10, 10, 4, 5, 6,5, 6, 7
My function has to return the number 3. Because there are 3 sets of mode; 10,5,6.
How do i implement this in my function because for now it just calculates the mode. It only return the number mode 10.

So I am trying to find the min, max, range, mean, median, and mode. The max number is right but the min isnt. Once that is corrected, i can get range and mean easily. Also, how to get mode and median. I am guessing the values in the arr2 would have to be sorted. This refers to the values in arr2 which are the calculated values in the formula. You can enter -2 and 2 for userMin and userMax.
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
cout << fixed << setprecision(1);
float userMin;

I'm trying to make a c++ program of this but i don't know how to use the bubble sorting.
Write a C++ application that asks the user to enter 10 numbers. The program then stores those numbers in an Array. The program should display the Mean , Median, and Mode.
Mean is the average of the 10 numbers.
Median is the average of the 5th and the 6th numbers. (But you have to arrange the numbers in ascending order first using Bubble Sort before calculating the Median.)
Mode is the most frequent number among the 10 numbers.

How can you get a monitor out of sleep mode in c#?
I tried the following, but then the monitor wakes up and falls back to sleep mode immediately.
Code:
uint SC_MONITORPOWER = 0xF170;
uint WM_SYSCOMMAND = 0x0112;
SendMessage(this.Handle, WM_SYSCOMMAND,
(IntPtr)SC_MONITORPOWER, (IntPtr)(-1));

I am writing code, which reads an input file (280 MB) containing a list of words. I would like to compute
1) total # of words
2) total # of unique/distinct words
3) mean/median/mode of word count (Link)
I managed to get done with 1) and 2), but my program crashes for 3). I am not quite sure whether there are memory issues or some bug in the code.
Code:
#include <iostream>
#include <fstream>
#include <string>
#include <map>
using namespace std;

I've been wondering if there's a function or procedure used to know the current video mode. An example of how this was done in Pascal:
function VideoMode : integer;
begin
if (lastmode = BW40) or (lastmode = BW80)
VideoMode := 40
else
VideoMode := 80;
end;
I've been told "conio.h" has a lastmode function, but it doesn't seem to be supported in Dev-C++ and Visual Studio C++. Is there a Windows function to know the number of columns in the current video mode?

I get this error when i try to run this code for an inventory in debug mode in VS. But for some reason it works just fine in release mode.
void Push_Back_Item(Item *item){
for(int y = 0; y < InvSizeY; y ++)
for(int x = 0; x < InvSizeX; x ++){
auto Iter = ItemList.find(std::make_pair(x,y));
if(Iter != ItemList.end()){
item->SetDead(); // ERROR
}
}
}
This isnt the full code though but it still gives me the same error.
The only thing "item->SetDead()" does is to set a bool to true.
This is the map i get the iterator from
std::map<std::pair<int,int>,Item*> ItemList;
This have been bugging me for quite some time now.

I'm currently working with linear VRAM (a buffer with 256KB memory, divided into four 64k planes, so plane 0 at 0x00000, plane 1 at 0x10000, plane 2 at 0x20000, plane 3 at 0x30000). Just add the index of the plane to that for the full address in VRAM.
I'm still wondering how to get a specific pixel from VRAM (x,y coordinate) when doing graphic modes (none color modes work, only the black/white pixels (1-bit) graphic mode works).
how I can get specific pixels from the VGA VRAM (having linear access described above) using Shift Register Interleave mode (VGA modes 4&5), 16-bit planar mode (Most VGA modes) etc.

i've got an assigment that requires me to overload some operators and add some objects together.
I will show the code and explain as good as I can.
void SArray::operator+= (const SArray &obj)
{
Sphere * tmp_arr;
tmp_arr = new Sphere[obj.antalobjekt+this->antalobjekt]; //antalobjekt = //Gets amount of elements in the arrays.
[Code]......
m_arr is the inner array for storing elements, do ask if something is not clear enough. The copy constructor works, so i have not included it.

I needed to know if there is any possible way to make a colorful text in graphics mode
Like each letter will have different colors using setcolor(random(20));

I am creating a C# windows application which allows it to connect to our devices and communicate with them.
Often we need to customise this application and I have made this easier by defining its appearance and actions within an XML file which gets read in every time the application starts up. This is working really well.
However editing this XML file can be pretty laborious and often requires many cycles to get everything correct again. So I have started to create a graphical editor which allows for the XML to be generated.
The problem I am facing is that I am using the same controls in the final program and the editor so my question is how should I structure the code so that each control knows when it is in "Normal" mode and when it is in "Edit" mode?
I have started using a simple boolean flag to indicate its mode, however this now means that within every function I need to check this flag and run code appropriate to that mode, this seems a bit over the top. Is there a better/standard way this sort of this is done?

I have a file in which I have written a structure called "Record".
Here is the struct definition:
Code:
#define IDSIZE 10
struct Record{
char id[IDSIZE];
int score;
};
Here's the code where I wrote to the file:
Code:
Record record;
char* id = "H12345678";
int score = 50;
record.id = id;
record.score = score;
file.write((const char*)&record, sizeof(record));
}
Here's a screenshot of the file in windows: [URL].... To the left is the id, 9 characters. To the right, well I'm assuming that's the score that I wrote.
And here's the problem, reading from the binary file:
Code:
Record record;
fstream file(argv[1], ios::in | ios::binary);
if(!file){
cerr << "Could not open the file." << endl;
return 1;
}
char* id = new char[IDSIZE];
[Code]...
The ID reads perfectly. The score...always returns 0, despite that it should show "50".

Use of the port series mode blocked under CBuilder RAD Communication with the robot to the Modbus Protocol, This is a c++ program which serves as a force a bit of %M65. And also to calculate the CRC16 at the end.
I supports M340 automaton.
I have not a force several bits at the same time

I have an idea which i will try to implement in C++,I want to compress file size through making my own numbering system which is 80-based number, I do really want to know whether this even possible ? I learnet that Hexadecimal uses symbols like A, B, C, D, E, F to represent 10,11,12,13,14,15 -- and that's what i want to do to my own numbering system but in a bigger scale .if possible: How can i use C++ to open a file in Hex mode ?

I needed to compute average median and mode for numbers in a vector. Im having a few issues I have already figured out how to calculate average and median just not mode. Also the program crashes when 0 is entered instead of exiting nicely. Also i keep getting a error on line 47 saying primary expression expected before else.
#include <iostream>
#include <conio.h>
#include <math.h>

I was doing a side project from my textbook about finding the mode, which is the number that occurs most often in a sequence of numbers. I racked my brain on this for an embarrassing amount of time and finally came up with this, which I think works but for some reason I still feel like I'm not done.
#include "stdafx.h"
#include <iostream>
using namespace std;
void mode(int *, int);
void main() {
const int NUMBERS = 15;
int list[NUMBERS] = {99,73,56,14,28,42,93,64,51,26,56,16,38,81,98};
mode(list,NUMBERS);
[Code] ....
Console Output:
Final Mode 56
Press any key to continue . . .
There it is, I would have commented more but I couldnt think of the right words to explain everything.

tell me where the errors in the below code are?
Extra info:
getrowsize() gives the size of a row in bytes (see VGA CRTC register).
getVRAMMemAddrSize() gives the size of a pixel in memory (1=byte,2=word,4=dword)
set/getBitPlaneBit(startaddr,plane,offset,bit[,on when writing]) sets/gets a bit on a specific bit plane offset (start addr is the start address register from VGA,
plane is the plane to read/write,
offset is the offset within the plane,
bit is the bit to read/write (0-7),
[on(when writing) is the value of the bit)]
[code]....
