In the following code I want to iterate through "Win32_OperatingSystem" to find all variables and their values. Using GetNames() I can get the names of all the variables but the subsequent Get() call fails to return a value.
I am trying to solve a MIP problem using C with Cplex linker. I need to find min value of two decision variables, as far as i know, i should write as a constraint because they are decision variables. "if" statement does not work for decision variables. here is some part of my model in C.
Code:
void TSPMIP(int Scenario, int Agency) { int i,j; double tmpDouble;
Question: State the values of each of these int variables after the calculation is performed. Assumed that, when each statement begins executing, all variables have the integer value 5.
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth.
I know that returning to main() is not a good idea but how will I loop the program to go back to the position selection when the voter is done voting for the last position.
when I run the program it seems fine. getting the votes from President to PRO Position is fine. The problem is how will the next voter vote without losing the vote (tally) of the previous voter?
FLOW: SELECT POSITION (a-e) ---> SELECT A CANDIDATE (a-c) ---> (this goes on until the position of PRO) ---> ( then go back to the POSITION SELECTION)
After every vote there is a case statement for which I can choose to vote for the next position, quit, or show results (and after showing the results it will go to the next position to vote)....
#include<iostream> #include<string> #include <conio.h> using namespace std; int pca=0,pcb=0,pcc=0,ptv=0;
The code below is suppose to output all the prime numbers between the values of startNum and endNum variables. but its not working correctly instead it display all the numbers between startnum and endNumber including non-prime numbers.

I'm trying to write a program to find values for arctan of x by using taylor series. An initial value of x is given by the user and then it should print solutions from arctan(x) to arctan(1) in increments of x+0.1. It prints correctly but gives incorrect values after the initial x. I'm new to c and need some way to 'reset' the functions f1 and f2 for each increment of x (I think...)
Here's the code
#include <stdio.h> #include <stdlib.h> #include <math.h> #include <iostream> #include <fstream> using namespace std; int main() { /* Define the beginning of the program and each variable. Also opens a text file to be written to */ FILE *f = fopen("arctan.txt", "w");
I have to do a project where a file with 60 rows and 17 columns is stored in an array. The purpose of the project is to find all the "peaks" and "valleys". A peak is considered a number that has a higher value than all 8 of its neighbors, while a valley is a number that has a lower value than all 8 of its neighbors. Here is an example where peaks are bolded and valleys are underlined.
im using a for loop to find the index values of the tied high scores and store them into string list then reference list in the second for loop to output it to screen however it isnt letting me use an array with index i as an index its self.
void printHighest(Student s[], int length){ int index; string list[10];//you're never going to have more than 10 people with a tieing highscore. index = findMax(s, length);
[Code] ....
For the time being I simply removed the idea of string list and just put the contents of the second for loop into the if statement above it. However, I am still curious as to if I can reference an index of an array in an index of another array.
I'm supposed to create a program that will find the min/max values of two ints, doubles, and chars, It's not completely done but here's what I have so far.

I seem to have reached a dead end in a program I am attempting to write.The purpose of the program is find the smallest, largest, and average values in a collection of N numbers. It needs to get the value of N before scanning each value in the collection of N numbers.I'm having trouble creating comparisons for each set. I have a feeling because of the way I structured my program, I'm unable to make a proper comparison. Maybe my approach was wrong as soon as I got to the for statement to loop N sets and N numbers.Here is my code so far:
Code:
#include <stdio.h> int main (void) { int num_sets, num_of_integers; int count, count2, set, sum = 0; int num, avg; }
[code]....
/* Here is where I would continue to attempt to make a comparison between sets to determine smallest to largest */
I am so close to finishing this program. It will find the median of an array of 5 values. I have one last error that I cannot seem to get to go away. Here's the code:
#include <algorithm> #include <functional> #include <array> #include <iostream> using namespace std; int main() { int integer1, integer2, integer3, integer4, integer5;
[Code] .....
The error states: "IntelliSense: no instance of overloaded function "std::nth_element" matches the argument list, argument types are: (std::_Array_iterator, std::_Array_iterator, unsigned int, std::_Array_iterator)
I am trying to create a simple interface on console to allow to input some values to some variables. For ex:
int main() { double a = 1.5; double b = 2.5; double c = 3.5; string x;
[Code] ....
However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.
I am really desperate on trying to make my code work. The code is to find the eigen values of any given matrix of dimension NxN. The input can be the diagonal of any NxN matrix alongwith its subdiagonal. The code works fine for N~350 or so but when i go beyond that these errors appear.
First-chance exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000. Unhandled exception at 0x00425ea4 in divide.exe: 0xC0000005: Access violation writing location 0x01141000.
But as i have never declared any variable statically and when i dynamically allocating memory with variables it should work like it does for smaller N values.
I am using Visual C++ to write an app. One problem is that the application will allocate a lot of object instances of a specific class CMyObject, maybe 400, 000. This will cause "Out of memory" error when total allocated CMyObject reaches 400,000.
To solve this problem, I just wonder when a new CMyObject instance is created, is it possible to specify so that the instance will allocate on a disk cache, or file mapping instead of the memory space?
C++ Create a Triangle class that has the following member variables: side1 - a double side2 - a double side 3 - a double perimeter area
The class should have the following member functions:
- default constructor that sets the value of all 3 sides of a triangle to 0.0
- a constructor with arguments that accepts values for the three sides of a triangle (member variables) as arguments
- setDimensions - a function that allows the value of the three sides to be entered by the user through the keyboard
- testSides - a function that determines if the 3 values entered can actually be the sides of a triangle. If they do not create a triangle, print the values entered and an appropriate message --The sum of any two side lengths of a triangle must always be greater than the length of the third side: so side 1 + side 2 > side 3 and side 1 + side 3 > side 2 and side 2 + side 3 > side 1 ( all three must be true for the 3 values to make a triangle)
- getSide1 - a function that returns the value of side 1, getSide2 - a function that returns the value of side 2, getSide3 - a function that returns the value of side 3
- getArea - a function that returns the area of a triangle: The formula for the area of a triangle (when the height is not known) is: A = sqrt (p(p-side1)(p-side2)(p-side3)) where p = (side1+side2+side3)/2
- getPerimeter - a function that returns the perimeter of a triangle: Perimeter = side1 + side2+ Side 3
- A displayTriangleInfo function that displays side1, side2, side3, area, and perimeter for a triangle object.
After testing your code for a single object, create an array of 5 triangles. Use a for loop and the setDimensions function to allow the user to set the values for the 3 sides of a triangle, test the vales entered to determine if the 3 create a triangle. If they do create a triangle than use the getArea and getPerimeter functions to calculate the Area and Perimeter for the triangle and use the displayTriangleInfo function to display all of the data for that triangle. If the three values do not create a triangle then print the 3 numbers entered and an appropriate message. In either case the loop should then move on and get the data for the next triangle from the user.
I just started programming and want to make the game cows and bulls. The problem is that after the loop has ended and both vectors are not the same I want the user to 're-input' the starting variables a,b,c&d but I don't know how to.
Code: #include "std_lib_facilities.h" int comparison(int a, int b, int c, int d) { vector<int>bc={ 1, 2, 4, 9 };
I've simplified things slightly - but the basic point is that both functions are in the same source file and they both have a static std::string called 'x'. Being static, I guess they aren't (strictly) local variables. So how does the compiler know that they're different entities? Does it encode their signatures using the function name or something like that? If I call each function separately I do seem to get the correct string...
I have created a windows form project in visual studio so that I can use a windows form to interact with the game class that I'm creating, but I'm running into some problems.
For one thing, I would like to be able to call Image::FromFile() one time only during initialization, and store the result in a member variable (called mBGImage). From what I can tell, the variable needs to be of type String^ (this caret symbol is new to me, but I understand it is the "managed code" version of the standard pointer, which would look like String*).
When I try to compile the following code (located in my header file) I get the error :
"error C3265: cannot declare a managed 'mBGImage' in an unmanaged 'BSG::BSGame'".
How can I store the result of Image::FromFile() permanently in my class?
When I try to declare a global variable of type "Image^", I get "error C3145: global or static variable may not have managed type System:rawing::Image ^"
