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 ..
When I run the program, when it displays the lowest temtpature, it shows the address instead of the actual number.
Code: /********************************************* * File: b.cpp * 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.
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; }
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.
//This program lets the user enter 10 numbers and then display the highest and lowest number.
#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;
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'm using the memcpy method, for that i'm getting the below error. memmove function also giving the same error message.
File Name : memcopy.asm rep movsd ;N - move all of our dwords

I have an assignment to create an address book in c++ where you can enter contact information and then search all entries via last name. I am trouble figuring out how to write a function that will be able to search an entry by last name. Here is my code so far:
#include <iostream> using namespace::std; class addBook {
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.
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;
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.
The following lines are giving trouble:
Code: DialogBox(pApp->getInstance(), MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, pApp->About); error: 'App::About': function call missing argument list; use '&App::About' to create a pointer to member
Code: wcex.lpfnWndProc= &App::WndProc; error: '=' : cannot convert from 'LRESULT (__stdcall App::* )(HWND,UINT,WPARAM,LPARAM)' to 'WNDPROC'
There is no context in which this conversion is possible
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
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 an assignment where i have to prompt the user to enter the name of a file then open that file and read names of students and what level they are at university
eg : John Wilkins, sophomore Dan Robertson, junior etc..
i did the code and it compiles perfectly, but when i input the name of the file it gives me error: string subscript out of range.
here's the code:
Code: #include <iostream> #include <cstring> #include <string> #include<ctime> #include <fstream> using namespace std; int * read_file(string filename)
