C++ ::  Algorithm To Read Duplicate Array Elements - Return First Duplicate Value Only

Oct 23, 2014

I have an algorithm which uses nested for loops, which looks for duplicate elements in an array. However, as soon as one duplicate element is found... the program will stop looking for more duplicates? My program continues to look for more even though one is found? I know there is a break command but I can't get it to work. Code is below:

output of program: Repeating element found first was: 2, 1

Although I want the outcome to be; Repeating element found first was: 2

#include<stdio.h>
#include<stdlib.h>
#include <iostream>
using namespace std;
void printRepeating(int arr[], int size) {
int i, j;

C++ :: How To Prevent Loop Running Over

Feb 18, 2014

i am writing a function that takes a delimited string and splits the strings into it's respective words according to the delimeter.

1) iterate through string and store delimeter position in vector array.

2) iterate through again and use substr to split into words and store again in a vector.

I then have a dictionary file, and am comapring each values in the string with each in the dictionary, problem is that it overruns the loop and obviously gives a subscript out of range error.

Code:
#include <iostream>#include <fstream>
#include <vector>
using namespace std;
//Start with string inputString
//Find delimeters ::pos as ints and stores positions in vector <int> array
//Run though string using 'find' and seperate string by positions of char32s
//Build vector<string> array of individual words in string
//Open dictionary file and loop though testing each words in vector string array against each word in dictionary

C++ :: Null Statement - Prevent Optimization

Dec 7, 2014

Recently I was looking into embedded programing of AVR microcontrollers.

At this site [URL] ....

I have encounter some code that implements delay

asm volatile ("nop");

From what I understand it is assembler code that creates delay - one processor clock long.

For C/C++ language it should be like ; or {} = null statement.

Now my question is how to implement this C/C++ code and prevent my compiler (WinAVR: AVR-GCC) to delete this command during optimization (-Os or -O2). Or is it simply better to use the assembler function.

I know I can use for-loop

volatile uint8_t foo
for(foo=0; foo<2; ++foo){}

but for that I have to create a variable = wasting 1 byte of RAM; correct?

C++ :: How To Prevent The Main Thread From Blocking

Feb 14, 2014

I have an issue where I iterate through devices and make driver API calls. Unfortunately, these calls take too much time and they are interrupting my real-time scheduler. I have 12 cores, of which one is 100% and the others are < 1%.

I'd like to multi-thread this thing. So far, I've replaced:

for (DeviceIterator d = devices.begin(); d != devices.end(); ++d) {
d->Write(words, numwords);
}

with

void* ThreadedWrite(void* p) {
WritePackage* wp = (WritePackage*)p;
wp->device->Write(wp->words, wp->numwords);
delete[] wp->words;
delete wp;

[Code]...

My problem is that this didn't improve performance at all. The main thread still takes too long to execute. Is there something I need to do to prevent the main thread from blocking?

C/C++ :: Prevent Endless Output Of Sentences?

Nov 16, 2014

After I have compiled and executed code below, and I have made an input of a string, the while loop takes over the control and outputs an endless flow sentences. How can I make sure when an input of string is made, such a thing does not happen? In Python, one can make a type check by the use of type() command, but such a command does not exist in C, so how can I prevent an endless output in case a string input is made by the user?

(The code below is supposed to check whether the number entered by the user is divisible by 7 or not.)

#include <stdio.h>
int main() {
int a = 0;
printf("Input a number!");
while (1 < 2){
scanf("%d", &a);
if (a % 7 == 0) {

Visual C++ :: Prevent DLL From Being Loaded / Injected

Dec 12, 2012

If you're writing a .dll you can prevent that dll from getting loaded into some processes by returning false from the dllmain.

I'm looking for a way to do it the other ay around. I have an exe, and I want to prevent a certain hook dll from getting loaded/injected into my exe.

A customer is running some software which loads a hook dll into our exe, and this is subsequently preventing our application from running as intended. Both our software as well as the third party app is required, and there is no way to get the third party dll changed. (no longer supported).

C :: Removing Duplicate Elements From Array

Nov 4, 2013

While removing duplicate elements from an array, if more than 4 array elements are same then removal does not work. however my logic seems to be alright. i reckon there is a problem with the conditions and assignments in the three for loops that i have used. the program is as follows:

Code:
/*c program to remove duplicate elements in an array*/
#include<stdio.h>
int main(void)
{
int array[30],i,j,k,n;
printf("

[Code] ....

Take for instance if the input elements are 1,1,1,1,1,2,2,3,5 then after removal of duplicacy the array is 1,1,2,3,5.

Visual C++ :: How To Prevent A Window From Being Moved Or Resized

May 20, 2014

I know I can set the window properties on creation, but I'm trying to figure out how to prevent a window from being able to be moved or resized. I've been looking online and it looks like it involves overriding the WM_SIZE, WM_SIZING, or perhaps the WM_WINDOWPOSCHANGED message handlers. I want to be able to have a menu option that "locks" the window position, and of course allows normal window behavior when the option isn't checked.
