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.
#include <stdio.h> /* fopen, fclose */ #include <stdlib.h> /* exit function */ #include <string.h> /* string library */ #define STRSIZENAME1 41 /* length of name */ #define STRSIZENAME2 100 /* amount of names */ #define STRSIZEAGE 100 /* amount of ages */
/* Name: main */ int main(int argc, char* argv[]) { [Xode] ....
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
I'm trying to pass 2 arrays into a void funtion, and return values to one function.
this is the the program I'm working with, after I'm done I have to split it into 3 files, a header, a main, and a separate cpp file for the functions to live in.
#include <iostream> using namespace std; void processArrary(int numberCount[], int Numbers[], int intnumberSize, int numberCountSize); int main() { int Scores[26] = {76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189}; int numberCount[8] = { 0 };
[code]...
The goal of this program is to separate and count the groups of numbers then output the amount of numbers in each group. Near as I can tell, everthing should work, but I'm getting all zeros to be displayed in each group.
That this will execute those binary instructions in hexadecimal notation BUT WHY? I don't get why that works since that's an array of data not a function?
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;
[Code] ....
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..
#include<iostream> #include<iomanip> #include<string> #include<cstring> using namespace std; class combineSort { public: combineSort() {
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?
So I am writing this code that analyzes a file called "analysis.txt" and prints out in an ouput file (called "report.txt") the results of the analysis, i.e.,(the frequency of all alphabet letters present in the file).
I am having trouble with outputing on the file2.
here is what I have:
Code:
#include<iostream> #include<fstream> using namespace std; ifstream file1;
[Code]....
I tried to lose the "<<" after the file 2, but it's still giving me an error. how to output a void function on a text file?
I have to write this program that is to store the name, address, id number, etc of a student. The data is supposed to be brought in through main and there will be multiple students. I'm not sure what commands I should use to bring it in.
EDIT: This will make more sense. In the .txt file the info will be written like
Name Last name Address etc.
I need to input that and use that for the appropriate number of students.
I want to write a code that gets three values from the user and puts them into three arrays. When the user enters -999, I want to print out a chart showing all the values they put in. This is what I have so far but it wont build. It tells me std::string is requested, but I'm not sure where to put it, and printArrays is declared void. How can I fix this?
#include <iostream> #include <string> using namespace std; const int ARSIZE = 400; void printArrays (string reportTitle, int levelsArray[], int scoresArray[], int starsArray[], int i);

I have a module that pings the network to find available devices using threading.
the money line:
var valids = range.AsParallel().AsOrdered().Where(ip => ip.Ping()).ToList();
The problem is, I need to display a progress bar while this function runs. I have the progress bar implemented with a background worker, but it won't update while the ping module is executing. I *think* it's because I'm using the available threads for the ping module.
When the user clicks a button, I need the ping module to run while the progress bar updates, or even just set IsIndeterminite to true. What would be the best way to accomplish this?
I was reading about void as function argument, but I did not fully understand it's meaning in C.
In C++ void foo(void) {} and void foo() {}
are the same. It means no arguments for foo function. But in C it's different. First function means the same as in C++, but second means
In C, an empty parameter list means that the number and type of the function arguments are unknown. But if it is unknown you can't use this arguments if user specifies same. Because here are no variables to store them. So doesn't result are the some? You do not get any arguments. O do I can get this arguments from some hidden variable?
For example.
void foo() { printf("%d", var); } foo(5);
It is very unclear for me. Do this apply to main function too?
int main(void) int main()
or can I use arguments given to int main() like given to int main(int argc, char* argv[])
