how to insert a variable for the size of array and prompt user to insert the elements for the array?
View 13 Replies View RelatedI have N vectors which look like this:
[1→m] [m+1→2m] [2m+1→3m] [3m+1→4m] [4m+1→5m]..... [{(N-1)m}+1→Nm]
I want to select 1 element from each vector without duplication of any combinations. Essentially only when all combinations are done with 1st element in first vector ,only then it should move to next element in first vector.
Say i have elements :[123] [456] [789]
my combinations should be like
147
148
149
157
158
159
167
168
169
247....
Also, I cant have any repetitions and only after all combinations of 1 are done only then the loop has to move to next combination ie 247 combination and so on.
I tried NCK (n choose k) command but it gave me random combinations. How should i go about it with using minimal for loops?
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

I want to prevent to type zero as the first digit in value in c code
Code:
char next_buffer[ 5 ];

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?
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;

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);

I would like to programmatically monitor a directory for new files, and if the file happens to be an executable, I want to prevent it from running. Something like a AV program.
However, I don't know where to start. Simple is best.
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).
I know how to do it in C, but in C++?
Here is my code. Let the variables be of type double.

View 2 Replies View RelatedI 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.

View 3 Replies View RelatedI created a C program that extracts some information from computer and displays it on screen. It is completed today and is going to be applied to startup programs of domain machines. It runs at logon and takes somewhat 5-10 seconds to finish execution. The output is shown on console screen & user can either close the window by clicking on 'x' or pressing 'Ctrl+c' during execution. How do i prevent both of these events?
Basically the most time consuming processes are
Code: popen("systeminfo","r");
popen("wmic qfe get installedon","r");
1st command is getting OS name,version and hotfixes installed.
2nd command gives me the date of updates installed.
I then filter out data & print required information only.

Parent > Multiple Child(Parent parent) > Child destructor deleting parent => next Child destructor crash
Example code: without using:
class Parent {
public:
Parent() {
for(int i = 0; i < x; ++i) {
for(int j = 0; j < y; ++j)
childs[i][j] = new Child(this);

If you read code, on Parent destructor i = 0 & j = 1 its going crash.
Parent will be deleted aswell, but it give me assert: _block_type_is_valid(phead- nblockuse)
I have a class 'A' which is almost perfect for my needs. Class 'B' uses class 'A' I've now designed Class 'C' and Class 'D' and noticed that there is a good chunk of code in class 'B', 'C' and 'D' for using Class 'A' is duplicated. I've separated out this code in specific, standalone functions in each of the classes. Now I'm wondering where this code should go. At the moment, the functions are duplicated in the three calling classes (B, C and D). Placing the functions into class 'A' would break the single responsibility principle. Inheritance to add functionality would likely break both SRP and LSP. The one that seems that it may work is composition.
However, Is designing a complete class just for a few functions over kill?
Would it be valid for classes 'B', 'C' and 'D' to access both the new class 'E' (which would depend on A) and the old class 'A' (which would have to be the same instance as the instance in the new class 'E'), or should the new class 'E' provide sufficient functionality so that Classes B, C and D don't need to access Class A directly? It would seem that its then an incomplete interface of the original object with additional functionality (ie, incompatible) Or should I do it a completely different way?
