I am struggling to find a replacement of NtQuerySystemInformation call for 64-bit Windows OS, like on Windows Server 2008 (64-bit). Need getting overall CPU utilization (average) over all CPU cores?
I'm trying to open a file (contains member information) and store the information in an object, which is then inserted into a linked list. However, the current code just leaves a blank command window hanging with nothing happening.
So I'm trying to make an employee list that holds the information so I can then delete or add from that array. I'm getting some errors regarding overloading function.
I have a method that traverses a list to compare a number from the list to user input from elsewhere in the program. I have tried a few different things and I am probably overlooking something simple but my problem is my if statement is executing the else statement every run no matter if the input matches. This function is to return the location in the list that the num matches. -1 if no match, 0, 1, 2, otherwise depending on the number of nodes.
int NumberList::find(int num) { int temp = 0, count = 0; ListNode *nodePtr;
Basically the question is to develop an application that allows: Create an application which stores information about people, along with a task list.
The user should be able to Store people's information
Name, Age, Telephone number, Address
-Retrieve information by entering name - Remove a person's record by entering their name -Return records for all people, sorted according to an information type other than age -Enter a task which needs doing, a priority entered for its urgency -View highest priority task on the list -User should be able to remove highest priority item on the list
How to develop this application on a console command line interface style or any other style.
I am making a console based database system. Because I have to keep inserting, editing , deleting data blocks from my record file I have decided to use either vectors or list to store the all records. From the file I shall read the entire vector/list and work with it to add , remove or edit record and then again write the entire vector/list to the file again. I figured it would stop all the weird things that happen when directly working with the file. Is it an efficient way ?Or is it totally unnecessary ?Is there a better way?
dynamically allocated arrays. int (*ttt)[2][10]; If I'm not mistaken this declares a pointer (that's all). This pointer has an intrinsic shape that makes it easier to access row, column without doing my own math to calculate the offset.
ttt = malloc(2 * 10 * sizeof(int));
So I should be able to access elements like this: ttt[i][j].
ttt[i][j] = 123;
But the compiler says: error C2440: '=' : cannot convert from 'int' to 'int [10]'...how to go about accessing a monolithic block of allocated memory using 2 or more dimensions, using some sort of casting to a known shaped array if possible. As opposed to doing i * cols + j type stuff.
Suppose you have defined a container of elements and you want do define a comparison function between elements based on the ordering of the elements in that container. What algorithm for the comparison would be the most efficient?
My current idea is to simply iterate from the beginning of the container, and whichever of the two elements is found first is the lesser (assuming the second is not the same as the first). It seems kind of naïve though. Any better performing algorithm? This is what I have so far:
Would perhaps forcing the container to have a random access iterator, like vector, and then writing a specialized comparison function based on that perform even faster? Or perhaps force the container to be a map to integers, and compare the elements by comparing the integer mapped values?
Now I would like to extract the data inside these comment tags and insert into excel sheet. Need to extract the comments in the xml tags shown in the able format? For example I want the value inside the <Autor> tag.
I'm building a simple little program for minecraft to reduce the repetitiveness, I'm using getpixel, it's slow, but i only need to grab about 6-12 pixels.
but the problem is, I can get the pixel data if I capture from the entire desktop display, but as soon as I tell it to grab from the active window (wich goes MUCH faster) it doesn't return any colour value's.
I'd rather not have to use getDIBits or program in java or anything since I want to keep it fairly kiss, and if it can't be done, then.. ah well, I'll just grab from the entire desktop, speed isn't to much of an issue, but it'll be a pain to keep the window at the same place.
Code: #include <Windows.h> #include <iostream> using namespace std; // vvv Ignore this, it's just used for retrieving the handle of a window without giving the full window name vvvv struct results {
I am trying to write a loop that will iterate through a char array in C and pull the IP addresses and test them to see if they respond. My ultimate goal is to have the first one that responds returned in the function, but the loop is not running correctly. It will run through right the first time, but then will start over again.

How do I do the operation of two integers that gives you the results?
I'm supposed to write a program that:
Asks the user for an integer Asks the user for one of '+', '-', '*', or '/' (as a character) Asks the user for another integer Performs the given operation on the two integers, and prints out the result of
Please enter an integer: 4 Please enter an operation (+, - , *, /): * Please enter another integer: 5
4 * 5 = 20
Code: #include <iostream> using namespace std; int main() { int x; int c; int d; char e;
I mean on the executable file. It just displays the results and quickly flashes away, cin.get() has no effect and system("PAUSE") is undeclared.
I never found a single sure way to pause effectively. Is there a method that works all the time? Sometimes cin.get() gets skipped even in the code itself. The IDE I am using is Code Blocks if that matters any.
I have created a game that functions correctly, however, for balancing and future changes, I would like to record results .txt document (its 1v1 btw). I already have code to determine who won and what I am looking for is some way to keep track of different match-ups for the different characters. Im looking for something like this:
the numbers are the amounts of wins a given character has over another character. I'm looking for code to open the .txt file and add 1 to the respective win total so I can do balance changes and such.
I am using Excel 2013, Visual Studio 2015. I began learning about Excel XLL. I wrote simple function which tests whether the argument is missing. Here's code:
The point of this program is to calculate how many cents the user would have after a certain number of days. The user is given .01 cent on day one, and this amount is doubled with each passing day. I cannot seem to figure out how to add all of the results. Currently, my program simply outputs them to the screen. How do I tell it to add all of the results and store the sum in one variable?
#include <iostream> #include <cmath> #include <iomanip> int main() { using namespace std; float totalF = 0;//total amount earned after number of days specified by user have passed
