The first row has two values - number of nodes (24) and number of links (76). Then it has all the link details (76 rows of data). I want to read this data. I have written out the following function:
First the structure definitions:
typedef struct {
int arcno;
int tail;
int head;
} arc_data;
typedef struct {
int forwardStarPoint;
int reverseStarPoint;
[Code] .....
The code is able to read the first line of data (i.e. it displays the numNodes and numArcs as 24 and 76). But then I get a lot of errors like this one
The problem is that ... Even though it is reading from a a file, it is not reading a one struct. In this piece of code I'm trying to read the last struct, which should be k... The struct itself is here
The problem is that i dont know how to do because 'getline' won't work i think.
the file looks like this:
******************* Inventory of MyInventory ******************* Some info More info ------------------- 000 Toys 6.25 a short description 126/44 Cards 2.25 some text ******************* Inventory of MyInventory2 ******************* Some info More info ------------------- 000 Toys 6.25 a short description 126/44 Cards 2.25 some text
So what I need to know:
- the name of the Inventory (MyInventory, MyInventory2...)
- the numbers in each row (000,126/44...)
- the name what it is (Toys,Cards...)
- the price (6.25,2.25...)
- and the description(problem here is, that there are not the same amount of words for each description)
I tried it with 'getline' but this is not working because the lines are so different each time.
I'm trying to get my program to read a series of comma delimited values from a file into a vector. However, I am unsure how to actually go about doing this. I've posted my best guess below but it's really just a stab in the dark and I always receive a compiler error.
I am building a program that will read from a particular web page. I have written it so that it will parse the page correctly, but I can only do it for a downloaded page right now. I would like for it to work simply with the URL.
I have seen things about "screen scraping", though I don't quite understand what it does - I think it's more for just parsing it, which I can already do.
If it is possible to automatically download that file, that is fine as well.
If it matters at all, the pages I am reading from are stories on Fanfiction.net.
Is not the first time I upload this program i know, but the problem now is that i try to export files, because i need to create an excel graph. But when I try to run it, I don't have any result, no file and no result of the program.
Code:
#include<stdio.h>#include <time.h> #include <cstdlib> #include <math.h> int randfun(double arrX[], double arrY[], int size); int cenfun(double arrX[], double arrY[], int size); int rotatefun(double arrX[], double arrY[], int size, double center_x, double center_y, const double angle);
So I am trying to create a program that reads a series of files and creates a graph plotting points from the file. So far my code looks a little something like this -
include <iostream> include "ccc_x11.h" include "ccc_shap.h" include "ccc_win.h" include <fstream> using namespace std ; int ccc_win_main() { cwin.coord(-10, -10, 10, 10);
[Code] ....
However when I run the program nothing happens. I think it has to do with the way I set up my files, which looks a little something like this-
The first thirteen numbers are the x values of the points, and the last thirteen are the y values of the points. Is there any other way to have my program read the file and display the given points?? I would use getline() however that would make my point into a string, and I dont really know how to convert a string to a double before putting the variable into a point.
In the usual case, its an easy problem. But it gets tricky in my case, since I am working with numbers up to 30 digits, unable to store them in any int, long, long long. Due to this obstacle, the user inputs a number and each digit is stored in my array individually.
I need these commas to print as I am cout the array. This means I only have array length to work with.
I want to use modulus, but I'm not sure how this would work. I have:
void prArray(int Array[], const int arrSize) { int mod = arrSize % 3; int remainingSize = arraySize; int counter = 0; for(int i=0; i <= arrSize; i++){ remainingSize--;
[Code] ....
Which outputs the first digits correctly, but leaves 4 digits at the end: 235423452345 -> 23,542,345,2345
I'm doing a project that takes in a input file with Quarterback statistics. It has their name, team, completions, sacks, touchdowns, etc. It has 16 different variables in all (17 if you count first/last name as two). So I'm trying to read them and I can't figure out how to jump to the new line after it's read the file and put the information in the variables I've created.
That's the program I've written. The loop keeps displaying the first line of the file over and over. How can I get it to go to the second line, then the third, then fourth, etc? I need it to display all the lines of the file until it reaches the end of the file.
I want to receive an information from a file. For instance, you created a file name "sample.txt" via fstream and stored a bunch of people's name, address, phone number in that "sample.txt".
Now, I want to see what's stored in this file. Suppose, I wanted some particular guys address, phone number by just typing is his/her name.
How to relate the name with address and phone number of particular people? I just started the file creating so I wanted to know about it.
#include<iostream> #include<conio.h> #include<fstream> #include<string> using namespace std; int main() { ofstream outputData;
I'm trying to add more student information to the specific txt file. I did struct my student information and separated it with an array with max size of 200.
The inside of my current file looks like
Toshi Aka Nonal Donald
The first one represent student[0] and next one is student[1] and so on till student[199]. Right now, only 4 space is occupied, which means the array has information till student[3] but not from student[4] (I guess it has null condition).
What I want to do is, I want to add a new student information to student[4] and till student[199] once at each time.
So, my prompt will look like Would like to add a new student? Y/N (if yes goes to below statement and exit if NO) Hi. Please enter the information of new student. ___________ Student added. Please press any key to continue.
If the key is pressed, it goes back to my initial prompt and continues till I press N.
I sure I'm not using for loop to do this thing, because I'm adding student name one by one.
However, the array is already occupied by other student name till student[3] so, I want to add a new student information to student[4] (I don't want to overwrite the current information). And if student[4] is occupied, then [5] and so on.
I want to take the informaition from this file and save it into a struct the file conteins name age year (in char) and a grade it is somthing like this
file Nikos Tolis 19 A 8 Iwanna Nikolaou 20 B 9 Kwstas Doukas 20 Β 6 Georgios Pappas 19 A 7 Iwannis Lekatis 20 Β 7 Nikos Ntoumas 19 A 5 Maria Oikonomou 20 B 6 Kwstas Argyrou 19 A 10 Irw Ntouma 20 B 8 Leuteris Doukas 19 A 6
I want to read till i found the '32' the space in ascii here is my code so far
Code: #include<stdio.h> #include<string.h> #include<stdlib.h> struct students { char *name; int age;
Create a simple data file like the example shown below containing the 4 dates below plus 10 or more additional dates. The file should include 1 date per line and each date should have the form MonthNumber-DayOfTheMonth-Last2DigitsOfTheYear with no extra spaces. All dates should be in this century. No error checking for invalid dates is necessary.
My Output displays like
February -19,1991
How do I get my program to ignore the dash between the dates?
#include <fstream> #include <iostream> #include <string> #include <cmath> using namespace std; int main(){ const int M = 13;
I'm trying to open a file (contains member information) and store the information in an object, which is then inserted into a linked list. However, the current code just leaves a blank command window hanging with nothing happening.
I created a simple program that writes some text to two different text files. how to create a program that would retrieve the information from those two files, and put them in a single file, first the content of input1 and then the content of input2. how to do this. Here is the program that I created that creates the two files.
#include <iostream> #include <fstream> #include <string> int main() { using namespace std; string input1; ofstream fout("input1.txt");
this last few days I've been coding this one particular file
Hero.cpp
namespace Hero { namespace { // all data here } }
then the code grew a bit to about 700 line
Then now I want to implement hero skill system It needs the access to data inside the unnamed namespace where I put just about everything.. but it's unnamed namespace, it's only valid within one file and I should hide all that data from Hero interface in Hero.h How should I do this ?
For my intro to c programming class, our homework requires us to read a data file and emit various bits of information. the data file looks like this
#Domain: the URL #Alexa: some kind ranking, small numbers are better #Rank: another sort of ranking, big numbers are better
#Domain Alexa Rank Site Name #------------ ----- ------- --------- amazon.com 13 1177136 Amazon.com google.com 1 4533883 Google youtube.com 3 3637788 YouTube
[Code] ....
I've started and am able to get the correct number of lines, and the alexa number, but I keep getting some errors and am just unsure where to correct my code. This is what it looks like;
Code: // Lexi Anderson //CS 156 #include <stdio.h> int main() {
I was trying to make a program in C that could take Personality Information from the user and store it in a text file. Then, when asked, could compare the results to other entries in the so called "data-base" and tell which is the best match. I tried a whole lot but couldn't think of a proper way.
(Stings and File IO are not my strong points)
I am using Code Blocks 10.05 and the standard GCC compiler.
So I have to read from a file, and store the information in separate variables. My problem is that for some of the information I need multiple words, and for others I don't, so I cant simply store 1 word into a variable and store the next in another in so on. To demonstrate what I mean let me give an example.
Dog Cat Blue Bird Snake White Horse
I am able to store "Dog","Cat","Blue","Bird"...etc in variables but I don't know how to make it so I can store "Dog" in one variable, "Cat" in a second variable. and "Blue Bird" in a third variable. "Snake" would be the 4th and "White Horse" would be the fifth. How can I read a file and manipulate the pointer to grab what I need?
cheapest item = Oranges most expensive item = Raspberries total cost = 55.44 shopper = Winnie B. The Pooh
When I run my code however, it doesn't get past shampoo and will continue to add shampoo to the total cost infinitely. How can I change the code to produce the proper information?
