This is the code I have so far. The goal of the assignment is to sort two parallel arrays, one with names and another with their ages, at the same time to alphabetize them. I am stuck with trying to pull the data from the file itself and concatinating it. I have searched ways to do so and this is the best I understood. So the error is it will get me the first person's name, but it won't get the age and move to the next line in the file. It just keeps repeating the same thing and I can't figure out why.
I attached the sample file with names and ages to view the format of the text file itself.
PS the other defined variables are used later for sorting the data. right now I am just trying to get the data itself and put it in an array but between my book and the internet I can't seem to store the data properly. That is also why I am printing it in the while loop as well so I can see what my arrays look like but I will take that out too once I know the data is good
using namespace std; const int SIZE = 40; const int COLUMN = 5; void getData(ifstream& inf, string n[], double tstData[][COLUMN], int count);

when I compile and run the code and have it display it does not read the first item into the 1-d array, instead it appears to read the 4th number from the left into the 1-d array and then into the second spot in the 2-d array, then again in its proper place and finally it has this number repeating through the rest of the arrays:
-92559631349317830000000000000000000000000000000000000000000.00 followed by the number 59.7 from the .txt and the long number again.
I am trying to learn about parallel arrays and files. I believe that I wrote a program that properly writes the data of the arrays into a file, but I am not quite sure how to take the next step and make a second program by bringing in the file I created and reading the information of the file back into two arrays to display them.
i'm facing some problems with the array, as I have my .h and .cpp files so do i declare them as per norm of how we usually declare a function?
pointtwod.h class PointTwoD { private: int xcord,ycord; float civIndex; LocationData locationdata;

when i compile the error message i get was even when i i put in int xord[]; in my PointTwoD.h file:

I am attempting to reconfigure a working code that before used while loops and if statements to convert a numeric score to a letter grade. I now wish to take this same code however I want to change the char convertGrade(int numScore) to simply use a parallel array as a replacement to the if statements.
The array needs to consist of 3 arrays of fixed size 5: int minScores[SIZE] int maxScores[SIZE] char letterGrade[SIZE]
I know the declarations need to go in the function convertGrade but this is the first time I have worked with arrays and I am having trouble trying to figure out how this array will replace my previous if statement.
In order to access the array elements I need to write specifications such as minScores[i] maxScores[i] letterGrade[i]
So the point in this code is to promt the user to enter a product ID. It then should search the ids array and display the corresponding price and quantity from the prices and quantities arrays. I'm sure this is quite simple but I am new to programming and having trouble understanding arrays. All it is doing is giving me the first subscript when I input a -1.
//Advanced34.cpp - displays the price and quantity //associated with a product ID //Created by Scott Knight on April 12, 2014 #include <iostream> using namespace std; int main() { //declare arrays and variables int ids[5] = {10, 14, 34, 45, 78};
I am having a problem with my program to calculate the GPA of a student. The problem that I am having is that I am not able to get my Total Point Value to display the sum of the two arrays. The multiplication for the array is correct and will display correctly, but instead of putting the total into the accumulator it will display the totals in a column. I have tried moving the coding for the calculation out of the loop that converts the letter grade into a point value,and placing it in it's own loop, but I still get the same display output. Below is the code that I have so far. I still have a few elements to add to the code, but they will be easy once I get this display to work right.
#include <iostream> #include <iomanip> #include <fstream> using namespace std; // Global const // prototype int main () { // Varialbes, Arrays
Class programming project where we declare two arrays, a sting array containing the names of the boroughs and an int array which which holds accident number for each borough. The main function calls getNumAccidents() function to fill the array. it then calls findLowest() to learn which borough had the fewest accidents. It should print out the accident numbers for each borough and then out the borough and accident number with the fewest accidents.
I'm able to get the program to kind of work. When I run it everything works fine but I am not able to get the arrays to sort and match up correctly..

I've been working on an assignment that deals with newspaper advertisements. I have two arrays:
categoryCode (the code for the advertisement's category such as pets, cars, etc) and numWords (number of words in the ad).
The arrays are dynamic.
My assignment has the category listed each time there is an ad associated with it and then its number of words for that ad. If this were a real-world issue I would want my output to list each category only once despite how many ads were in it, list how many individual ads are in the category, and its total number of words for the ads in that category. When using parallel arrays, is there a way to do this?
Let's say I have categoryCode with three elements {5, 5, 7} and numWords {10, 12, 15}.
How would I make the numWords add together only when the categoryCode values are the same?
I would want the output to print: Category 5 Ads 2 Words 22 Category 7 Ads 1 Words 15
rather than how my instructor is having us do it like this: Category 5 Words 10 Category 5 Words 12 Category 7 Words 15
I think I'm getting hung up because my mind is confusing the element's location in the array with the element's actual value and I'm probably making this harder than it should be. How would I compare the categoryCode values in a dynamic array? If it were a fixed size I think I could just compare categoryCode[0] to categoryCode[1] and so on, right? But in this case I'm not sure how I would go about that.
In pseudocode and in C code, declare two 1-dimensional parallel arrays of Integers to store the age and weight of a group of people that will hold the information of up to 10 people. Use a For loop to iterate through the array and input the values. This is the code i have, but my array is showing up as 11 and not 10?
Say I have 5 vectors of unsigned char each of size 5. I want to take the max of each index and store it in a new vector. What is the most optimal way to accomplish this?
I'm making a Jeopardy game and when I read text from a file into arrays to set the categories, questions and answers a couple of the strings are not terminating and they are printing that junk box thing at the end.
When I use the debugger and print the problem strings they are showing up as "Thanksgiving21" or "Calvin Klein21" but all the other strings aren't having that problem.
Then for example I will change "line[strlen(line)-1] = '';" to "line[strlen(line)] = '';" and other strings will have that problem but not those stated ones. I'm using line[strlen(line) - 1] = '' to get rid of the newline fgets appends on the end of the strings.
I have an EDI file whose structure is given below. This file has multiple records, each record contains a header (e.g EDI.DD.0000000001.20130809), then contents (i.e multiple paragraphs of text) and then footer (e.g End of Report/No EDI Activity). I have to read that entire file using regular expression using three groups.
I am using following regular expression to read the file.
That expression reads the "header" and "footer" in respective groups properly but didn't pick the contents between header and footer in "contents" group.
I have changed the font of header and footer in below file to understand the format. I am using asp.net 3.5 framework.

how I can read information from a text file into an array so afterwards I can display the array and it will show the contents of the text file?
the information inside my text files consist of names and numbers like so: "Collins,Bills 80" should I separate the numbers and names into two separate text files one for names and one for numbers?
So I have a small program which is supposed to write and read multiple objects from a file, but for some reason it doesn't write the information when I use "fstream" to create the object from the fstream class, but it does when I use "ofstream". Also, it doesn't read the information from the file no matter if I use "fstream" or "ifstream". I watched a video where this exact code worked just fine, but it just won't work when I run it. I'm using Dev C++ 4.9.9.2, I don't know if that has anything to do with it, I also tried it with Code::Blocks, didn't work either.
Here's the code.
#include <iostream> #include <fstream> using namespace std; class Person
A company uses two text files: one to store employees' details and another to log their sign in/out time.
The details file - called details.txt" has the following format: ID, Name, Date of Birth, SSN, Department, Position - separated by spaces.
An extract from the file looks like this:

I used to use map to access elements. map has a good feature that it sort the element automatically. Now I need a map which can access element through multiple key values. So I choosed boost::multi_index_container. I defined a container as follows.
struct elem { int a,b; elem(int aa,int bb):a(aa),b(bb) {} };
typedef multi_index_container <
[Code] ....
What I am wondering is whether boost::multi_index_container can sort elements automatically. Specifically, are all elements extracted through iterator from begin to end shown below having b values between 2 and 100?
test t; test::iterator begin = t.lower_bound(make_tuple(1,2)); test::iterator end = t.upper_bound(make_tuple(1,100));
I have array of 100 elements and I'm trying to write elements which index is smaller than the index of the maximum element of the array. My problem is that I can't determine how big this array should be . I found which is my biggest index.
