C/C++ :: Find Number Of 1 In Array For Error Detection
Mar 24, 2015
I'm receiving a char array consist of 8 characters, what I want to do is find the number of set bits in that array and then send it(total number) as a character to the transmitter so he can check, data is transmitted using serial port(RS232), where processing of data is done by DE0 FPGA.I've tried to use TestBit but the compiler doesn't know this function(I added #include "bit-manipulation.h" but it doesn't recognize this either) ...
-- the code of my project:
filed = open( "/dev/uart_0", O_RDWR );
if (filed < 0){
printf("the port can't be opened
");
[Code] .....

Q. WAP to find the next palindrome number larger than the input number.
for eg:-
Input=25
Output=33
The program is giving correct output for number with all digits '9';
why is it not giving output.
#include<iostream>
#include<string>
using namespace std;
int main() {
int len,flag=1,count=0,num,ind;

I want to find number of comparison and number of exchanges from a list or other than a list. My list is this
12 5 11 19 4 7 8 10 9 6 22 2 9 1 32
First, I am looking for number of comparisons from a list of 10 numbers with 21inversions made by selection sort, insertion sort, exchange sort.
Also, I like to find number of exchanges from a list of 10 numbers with 21inversions made by selection sort, insertion sort, exchange sort.

Using VC++ 2010 Express. I am creating a dll to export a simple Multiply function so I can use it in Excel/VBA
These e are the steps I am following :
. Create a Win32 C++ Project and give a name. For example: CallDllFromVBA
. Select the DLL option in the Wizard and click Finish
. In the CPP file (here CallDllFromVBA.cpp), add the following code
#include "stdafx.h"
int _stdcall Multiply(int x, int y) {
return x * y;
[Code] ....
The Build output show everything is ok as follows :
CallDllFromVBA.cpp
CallDllFromVBA.vcxproj -> c:documents and settingsadministrateurmes documentsvisual studio 2010ProjectsCallDllFromVBADebugCallDllFromVBA.dll
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
In VBA, I insert a module and add the following code:
Declare Function Multiply Lib _
"c:documents and settingsadministrateurmes documentsvisual studio 2010ProjectsCallDllFromVBADebugCallDllFromVBA.dll" _
(ByVal x As Long, ByVal y As Long) As Long
Sub test()
MsgBox Multiply(2, 4)
End Sub
When I run the Test sub I get the error: 453 - Can't find dll entry point
I also opened the CallDllFromVBA dll with Dependency walker and I can't find the Multiply export function - In fact, the dependency walker doesn't show any function exports at all for the CallDllFromVBA dll !

I can't seem to find the logic error in my perceptron. The perceptron's feedback function pushes back a bias of 1.0 into the input vector, and calculates the dot product of the input vector and it's weight vector, and returns 1 if the dot product is > 0, and -1 otherwise. This will determine whether the inputted point is above or below the hyperplane given by the functor.
The training function instantiates a trainer object , which feeds it a vector random numbers, along with the correct answer (in this case, whether the point is above or below the hyperplane given by a functor). It then calls the feedback function, and subtracts its answer from the correct answer, and updates the weights by adding the input vector to the weight vector, and multiplying the weight vector by the error, and by a correction factor, in this case 0.01.
Typedef.hpp
Code:
#ifndef TYPEDEF_HPP
#define TYPEDEF_HPP
#include <vector>
#include <random>
typedef std::vector<float> FloatV;
typedef std::random_device RNG;
typedef std::uniform_int_distribution<> UID;

I am trying to find the max number entered by the user, and it should terminate when a negative number is entered. For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.
#include <iostream>
using namespace std;
int Max(int x);
int main() {
int x;

take a look at this project : [URL] i want to change this project for this purpose : when a USB PRINTER is connected show a message that tell us -> hey this is a printer. which part of this project should i change and how can i separate printer devices from the others?
note: if you are using visual studio 2010 or higher and get error for this line after conversion :
#define _WIN32_WINNT 0x403
just replace all of such these lines to stdafx.cpp file. means stdafx.cpp at last should be like this :
// stdafx.cpp : source file that includes just the standard includes
// HWDetect.pch will be the pre-compiled header
// stdafx.obj will contain the pre-compiled type information
#define _WIN32_WINNT 0x403
#include "stdafx.h"

"Unhandled exception at 0x001631c6 in DiasQuarkP1V0.exe: 0xC0000005: Access violation reading location 0xd5bf0c38." and it shows the xstring library.
this is my main, is their anything wrong with my code?

I wrote a program with a recursive() called finder. But it dose not work properly,at run time it becomes to a infinite status. How to detect the error at runtime. Here is the code.
#include<stdio.h>
void finder(int x,int y);
int tot;
[Code] ....
I think the error is the changing value of x after a round of for loop.

Still working with SDL2 and c++ my map collision is messed up since I implemented my Camera.
I do understand that everything has a relative Position on the Screen, depending on the camera.
Problem No. 1: The camera is not moving as fast as the Player, despite having the absolutly same velocity (4/-4)??? How can this be O_o
Problem No. 2: My tile collision is totally messed now. Probably its because of the difference between the Player Position and the camera :/ So if you can solve Problem no. 1, Problem number 2 might work out on its own :)
I will upload the code to github [URL] .....

i am having trouble finding a way to detect integers from an external text file. i currently have this code:
while(inputfile.get(wc))
{
char character = inputfile.get(wc);
if (character + 1 != NULL)
{
cout << character << endl;
}
}
this does not work as if (character + 1 != NULL) comes up with errors.
is there a way to detect ints?

I've been working on my 2D platformer for a while, and I'm running into a couple of problems. It seems to become laggy even when only about 25 entities need to do collision detection with the 8 walls in the area.
Only one thing to note: the BOOST_FOREACH(const Edge& edge, this->GetCollisonBoxEdges()) { sections actually aren't a loop, all players and enemies are basically a vertical line for purposes of hitting walls, so that's why there is some weird stuff in there (like assuming the edge is oriented a certain way, etc).
Asset::WallCollision Asset::GetClosestWallCollision(const std::vector<const Room::Wall*>& walls) const {
typedef std::pair< sf::Vector2<CoordT>, sf::Vector2<CoordT> > Edge;
const Room::Wall* wall_hit = NULL, * landing_wall = NULL;
util::intersect_ret temp, closest;
VelocityT para_vel;
if(this->m_StandingOn) para_vel = this->m_StandingOn->get_unit_parallel_vector() * this->mVelocity.x;
else para_vel = this->mVelocity;

Write a function which takes string of integer numbers and length of a string. Function need to return value of element which is close to mean of all numbers and transform string without that element. If are more numbers in same "distance" of mean, function need to find first and throw that number-element.
In function without []..
with pointers.
I wrote this code below, programm find mean of elements and if mean is equal to any element of string.. the programm return that number. Idk how to delete that number and how to find closest.. for ex:
String=[4,7,10,3]
sum=24
mean=6
The progoramm need to delete 7 and new string look like String=[4,10,3]
insert Code:
#include <stdio.h>
int main()
{
int n,i;
printf("Elements of string ?
