I am getting an error...
Error1error C2109: subscript requires array or pointer type451
PHP Code:
#include "stdafx.h"
#include <conio.h>
#include <iostream>
using namespace std;
//Function prototype
int searchList (const int [ ], int);
[code].....
The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code:
#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>
using namespace std;
int main(int argc, char *argv[]) {
ifstream inFile;
string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.
Basically I initialize an int array of size 10 with zeros. Then element 7 is changed to 1. Via cin I collect a user input (integer) which is the number to be searched.
Now the problem is that the search function from the book is somehow not working. I added a function to see how the array looks like and there is definitely one element with value 1 that should be found, but it simply isn't. The function always returns -1 (element not found).
The program compiles, but doesn't work as it is supposed to.

I have to search an array of struct students on the basis of their first names, last names and roll numbers .. so far i am done with the input of the student first , last names and roll numbers . I have problem in searching the array ..
Code:
#include <iostream> Code: #include <string>
using namespace std;
struct Student {
string FirstName ;
string LastName ;

When I run the program, when it displays the lowest temtpature, it shows the address instead of the actual number.
Code:

* Description: Create a C++ program that declares a 100-element array of doubles representing temperature readings. Pass the array to a function to be partially filled by the user. When the user is done entering temperatures, the function should return the number of elements added to the array. The main function should then display the maximum and minimum temperatures in the array.

I have a linear search algorithm set up to search through an array of class objects it works but the output does not match, when i search for a particluar name in the array the 1st and third values int the array are found but the second value is not found..
below is my code:
int linsearch(string val) {
for (int j=0; j <= 3; j++) {
if (player[j].getLastName()==val)
return j ;

I'm trying to open a text file from my computer and randomly output a random line of text (string) onto the console. How do I go about doing this?
So for example, if my text file, "StringTextFile.txt" had 50 rows of strings datas (not integers or chars), how would I randomly generate a line of word from the 50 rows of words in the StringTextFile.txt and output it onto the console?
This is how far I've gotten, which isn't much, but somewhere. I don't even know if my code even makes sense, at this point I'm just randomly shoving code together.
#include <fstream>
#include <iostream>
#include <string>
#include <iomanip>
#include <string>
#include <cstdlib>
#include <ctime>
[code]......
My program generates an array of random numbers. I want to then search a specific number within the array. If the number is in the array then a message apopears on the console saying that its there. I'm using the binary search algorithm to do this.
#include <iostream>
#include <ctime>
#include <cstdlib>
#include <iomanip>
#include <cstring>
using namespace std;
int size;
int getSize() { return size; }
[Code] ......
What is the program of this pseudo code?
Set found to false.
Set position to -1.
Set index to 0.
While found is false and index < number of elements
If list[index] is equal to search value
found = true.
position = index.
End If
Add 1 to index.
End While.
Return position
I am having a problem printing out the results for my code, It is supposed to print out the largest and smallest value in the array, but keeps giving me a value not entered and I don't know why.

#include <iostream>
#include<stdio.h>
using namespace std;
int main() {
const int NUM_ENTERED = 9;
int number[NUM_ENTERED], highestValue = number[0], lowestValue = number[0], count=0;

on a customers pc I have the following problem:
I want to run an exe file with CreateProcess, but this generates the error 193 which means
ERROR_BAD_EXE_FORMAT
%1 is not a valid Win32 application.
This is strange because there are no known problems with this file before for many years on many different windows versions.
The customers uses win7/32.
I use it with win xp and win7/64.
The file was compiled with vc 6.0.
What can cause this problem?
I load an image(768*256) using a file path(OpenImageFilePath).
After load an image, I start to read the loaded Image data using GetBits method and plot the same image data(768*256).

I have successfully declared and opened connectionPtr and recordSetPtr objects.
The follwoing code is giving an error message that "item cannot be found in the collection"

If i replace "[String]" with "String" then above statement executed successfully.
How can i execute the above statement with "[String]" without errors?

My .csv file is like:
Bone,origin,deep/superficial,location, action.
with list of 38 bones.
This is my main.cpp:
#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>
#include <cstdlib>
#include "Action.h"
#include "Action.cpp"
[Code] .....
For action, if user enters action, it will output the bones involved with that action.
For strengthening, if user enters location, it will output bones involved with that location.
For dagnostic, if user enters bone, it will output location of bone and whether bone is deep/superficial.
How I could search in csv file for these.
WPF window I'm working on. I have a window that has a textbox to enter a name to search a database table for, and when the search button is clicked, the ID for that username will be returned to a separate textbox. The code I've written atm doesn't seem to be working, but it looks fine to me. Here's what I've got;
private void btn_SearchUsers_Click(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrWhiteSpace(txtb_SearchName.Text))
{
SqlConnection sqlCon = new SqlConnection(conStr);
[Code] .....
So, I have the value entered into the textbox to be searched for stored in a variable, I'm selecting the ID from the table when the name in the variable is found, storing the result in a DataTable, and then in my foreach loop, if I find the name (the name column being index 1 in the table), I set set the ID result textbox to equal the ID for that name (the ID column being index 0 in the table). I think the foreach part is what's throwing me off. Maybe the column stuff? My Users table is like;
ID Name
1 John
2 Roger
3 Mike
The following code it taken from msdn library but it is failing to compile.
the following code has a header where all the variables used here are stored in header App.h.

I haven't had to modify them much for VS2010 so far. Right now, (I think) I have created the dialog box, and the menu as a class and a resource, respectively. However, when I call
Code:
void MFC_Tutorial_Window::OnClickDialogNew()
{
NewDialog dlg;
dlg.DoModal();
}
I get an error 'DoModal' : is not a member of 'NewDialog'
I suppose somehow I need to link the menu to the dialog box?
I believe I've added the references, included the libraries and essentially followed the instructions. Apparently I'm not very clear on how to make resources interact with new classes.

I have a VC solution . This solution contain 1 execute project and 10 library projects. The libraries added to the execute project by
#pragma comment(lib,"../outputbin64/lib/mylib").
When i comment these lines to not be added these libraries to the execute project , i will have link error like this :
LINK : fatal error LNK1104: cannot open file '../outputbin64/lib/mylib.lib'
My library projects not added to execute project with another way.
My question is why the execute project will link the libraries that not added to project programmatically?
