Afterwards I'm using this as a check throughout my application:
if (dbCount > 0) { // do something }
When I execute this code I'm getting the following error: "Operator '>' cannot be applied to operands of type 'method group' and 'int'"
So I'm guessing it has something to do with the cast of the dbCount-object but I don't understand why as I already stated that the count-object to be an Int32.
Basically, say i wanted to sum all the values enter for x. First, i ask the user how many x's there are, then create a "for" loop to ask for x1, x2, x3, .. xn. Then i want to know the cumulative total of x. How would i do this? This is the sample code i have made right now inside of my main function:
Code: int N; int I; int X; //This is where i ask for how many x's there are// }
i am doing some practice problems and i can't seem to figure out how to do this. basically we have a students number of test scores, then the name followed by the scores they have in a text file. Then we have to make a class with a constructor, copy constructor, destructor, and overload the = operator and the input and output operator. Are we suppose to call the text file in the input overload operator?
Here is what i have so far.
This is my header file.
#ifndef STUDENTTESTSCORES_H #define STUDENTTESTSCORES_H #include <string> #include <iostream> using namespace std; class StudentTestScores{ private: string studentName;
[Code]...
i am 100% sure the overloading the input is wrong
here is the implementation of the constructor copy constructor and desctructor
#include <iostream> #include "StudentTestScores.h" using namespace std; StudentTestScores::StudentTestScores(string name = "", int numScores = 0) { studentName = name; numTestScores = numScores; if (numScores <= 0) testScores = NULL; else

The program is suppose to use all the information and read from the notepad and output the exact things as the notepad file
I'm using CStatic inherited class in my code and creating static text boxes dynamically. Now for assigning unique control ID I'm creating a static control from resource editor and destroying it before calling CStatic::Create() and using its control ID say ID_STATIC_SAMPLE.
If I do not use this parameter of Create(), the static control is also being created, so what is the use of this unique ID. And any other better way to assign a ID for dynamically created static controls.
I'm trying to write to a named pipe created by a service, as we all know the session 0 isolation implemented in vista and forward makes this task a bit complicated.
well at this point i managed to make almost all to work but my real problem comes when i try to write on the named pipe from my GUI application with no administrator rights
If i run the GUI application with admin rights it works 100% but, I don't need that application to require the user admin rights and for security reasons i rather to leave it without admin...
so i started my research and i found that there is a way to achieve this by calling CreateNamedPipe() with a low integrity security attributes...
well how to implement but i finally made it, the problem is that it gets worse than passing null security attributes, it works with admin rights with NULL security attributes, but when i pass the low integrity security attributes it gives "access denied" even when using admin rights, so i guess im passing the wrong security attributes but how to manually create the security descriptor string.
[URL] when I try to write my output to a file. I am building a life insurance premium calculator with c++. What my calculator does is read in a text file called "policies.txt" containing a number of different policies. For example:
Pol1 M N 20 100000 1 .04 99 Pol2 F S 30 100000 1 .05 99 Pol3 M S 72 750000 1 .03 99 Pol4 F N 45 1000000 1 .05 99
And using this, it creates a single premium. Once the calculator calculates the premium of each policy, I want it to write out the premium amount of each policy to a textfile called "output.txt". The problem is that when I check my "output.txt" file, only the premium for the last policy shows up. It only reads:
Premium for Pol4 is 220384 When I want it to read:
Premium for Pol1 is 14101.6 Premium for Pol2 is 14221.2 Premium for Pol3 is 582391 Premium for Pol4 is 220384
How come only the last policy is showing up? and is there any way to make all four policies appear in my output text file? Here is my code:
My program involves trajectory planning using cubic spline method for a robotic arm. In the process, I had to calculate joint angles for each point in the path. In the last few lines of the code I need to write the values for counter and theta1 into a text file which I called "Test.txt". I am doing this using a nested for loop(the counter runs until it reaches 19 and hence need 19 theta1 values corresponding to it). However, I can't get all the theta1 values transferred to the text file.The statement within my inner loop is wrong and don't know how to fix it.
Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
using namespace std; int main(){ int number; int count = 0; int numOfGuess = 0;

I am getting an anomalous output. Before all the iterations of for loop could finish, the program enters into the invoke_thread_S() and I can see the remaining iterations of for loop happening after thread S is finished.
What could be the problem here. Can I put a 'sleep' before I enter into invoke_thread_S() function, I tried it with a very small amount (in nano seconds), but that did not solve the problem.
How to ADD a call to the FindMostExpensive function AFTER the main display loop, and use the index returned to display the information about the most expensive car?

I need starting a do-while loop in my program that runs up to 10 time that asks the user to enter up to 10 scores, which include the slope and rating for the course, and calculates the handicap for each score.
Here's what I have so far:
Code: { //This program calculates a golfers handicap. #include <iostream> #include <string> using namespace std;
I'm new to programming and i'm trying to do a certain task. I want to use a for loop to read certain data from a txt file and print them to a console. I'm trying to read student names and their grades.

I am creating a binary search program that lets the user input up to 10 integers and then the program displays the array and sorts it. When the user is prompted to select an integer, if the integer is in the array, the program responds with the array subscript part. I can get the loop to work once and maximum twice, but then it wont search for the array or say value not found even though the number in in the array. I tried making the values NULL but that only lets me go through it one more time.
Here is my code:
#include <iostream> using namespace std; //Functions void printArray(int); void selection(int); int binarySearch(int,int,int);
The user will first enter the file name to be processed. The program can do the following 5 tasks:
1. Count the number of words 2. Count the number of alphabets (without punctuation marks) 3. Count number of sentences. 4. Count the frequency of each vowel. 5. Count frequency of the following three words individually: FAST, computer and engineering
There should be a proper menu through which the user can select the desired task. The program should continue until the user asks to terminate it.
Here is what i have done so far:
#include <iostream> #include <cstring> #include <fstream> #include <cstdlib> using namespace std; int main(void) { int opt=0; //option number ifstream fin; string filename;

There are a few problems.
1- When I enter option 'q', an infinite loop starts. 2- The first time, the program gives the correct value. After that, each time it gives answer ZERO. 3- The last part is not working. I experimented something which failed. I don't know how to do the last part.
From the example given below, I would like to Generate a matrix who stores a generated array for each iteration. I have an understanding of inputting single elements to a matrix but how can I input an array to a matrix. let's say I would like to input and array of 4 elements that should be stored as a single row of the generated matrix and do this for an infinite while{true} loop.
I am attempting to create multiple labels in a for each loop for each tag text (using htmlagility pack). My current code only creates one and doesn't change the first value (Which is AAE). I am using the labels to later input all the label.text into a database after the initial loop has finished (not shown).
foreach (var tag in tdTags) { MessageBox.Show(tag.InnerHtml); Label label = new Label(); label.Name = "contentName" + tag.InnerHtml; label.Text = tag.InnerHtml;
I have this if block that is supposed to be creating a pipe then forking and I would like to combine the while loop below it with it. How would I do that?

I am doing an exercise that reads in a text file and loads the data into a struct. My problem is it doesn't read anything from the text file. I think it's the way I'm loading the data. Oh, it does read in the first record that tells the program how many contributor records to create, but nothing after that. Here it is:
Code: // #include <iostream> #include <fstream> #include <cstdlib> const int strsize = 30; const int SIZE = 60;
