My main issue is that when I store just one value into a simple integer variable, it gives me a big negative number.
My goal is to store a file that reads like this into arrays:
2014 1 23
2012 2 15
2013 1 25
etc
Where I would have the first column in an array, the second in another and the third in third array since I am not allowed to use multidimensional.
Is something like this possible and if not how can I make this work?
fscanf(in, "%d %d %d", &i, &x, &arr[i+x]);
I need to read input from a file , which contains multiple sentences of varying lengths. After each new line char, i need to store that sentence into an array.
#include <iostream>
#include <cstring>
#include <fstream>
#include <cstdlib>

I'm trying to read in lines for a file and storing it in an array. This is what I have so far. Am I allocating the memory correctly?
Code:
typedef struct {
/* declartion of variables */
} App
typedef struct {
[Code].....
How do I access the array content? I'm suppose to strtok the contents from the lines stored in the array and use it again.
I am creating a program and am having trouble with one part. The input file looks like:
Code:
2
3
Bill Jeff Steve
Linda Brittany Jessica
3 1 4
2 1 9
8 3 7
6 4 9
4 8 9
6 9 4
Where I am stuck is putting the numbers into the string array. For example, Bill's scores should be set up as Bill's scores should be set as
Code: bill_score = {3, 1, 4}
and when this code is ran
Code:
for (i=0; i<3; i++) {
printf("%s - ", men[i]);

here is my problem given below Input values (say 10) from user in array, if the value is even then place at even index else at odd index. Then how could i solve this problem?
View 2 Replies View RelatedThe problem deals with writing a program to geta series of integers from a user and storing those values into an array. Then use a function called selection_sort, when given an array with n elements, the function must sort the array from smallest to largest values.

I am working on a small c++ project where i read from a csv file with information in this format:
string,string,int
string,string,int
string,string,int
And all of the above information is one person. As is "John,Peter,23" is first name, last name, age. When there are multiple people in a csv file how can i parse through and separate the information in a string and int for later use?
I know how to do this in c++ with fstream and std::string and getline and so on and so forth. Im writing my code solely in c however. I can't get g++ installed so figured it was a good excuse to learn c instead of using the equivalent c++ abstracts.
My problem is, I'm making a game in c that I have made in c++ but have ran into an issue with my map. I want to read in my map from a file which just looks like this:
Name of Town
* * * * * * *
* * * * * * *
* * * * * * *
etc...
so i tried using fscanf to first read in the name of the town (stored in a char*) then read in the characters (in this case '*')(not including white spaces becuase i can just print those) into another char*. what is the better way to do this?
I would like to store the titles of a CD and then read them. I have started a program but not sure how to display or make sure it is storing it in the .txt file.
#include <iostream>

how to read a csv file where the data is seperated with commas so the csv file looks like:
programming,03,60,141,01,W,2015
programming,03,60,141,30,W,2015
Algebra,03,62,102,02,S,2013
Religion,08,98,938,20,F,2014
So i need the name of the course in one variable, the course code (ex 0360-141-01 for line 1) in another variable and the term (ie W2015 for line1). So i got the name done but cant figure out the course code since i need more than one value that is seperated by a comma. my code is:
#include<stdio.h>
#include<string.h>
typedef struct CourseInfo {
int courseID;

I've created a class that is supposed to store first name, last name, date of birth, date of death, and a fact about a person (all variables within the class). Im trying to fill these variables with a read function. it reads a .txt file like this
Firstname Lastname 1987 1988 this guy did this
The problem is, I don't know how to handle the last variable. the variable needs to hold the entire "this guy did this" sentence. i made it a string, just because i was clueless, and as expected, it only holds "this"
this is my .h:
#include <string>
#include <fstream>
#include <iostream>
using namespace std;
class Person {
public:
Person();
Person(const Person & person);
[Code] ....
Here is the read function in the .cpp:
bool Person::Read(ifstream & input) {
return (input >> fname >> lname >> dob >> dod >> fact);
}
I am trying to read and store a txt file with format below:
2.5;abc;2,4000
2.5;bef;3,2000
2.5;ref;3,1000
I try the fscanf( pFile, "%d;%s;%d,%d", buffer,buffer2,buffer3,buffer4 ); to store 2.5 to buffer, abc to buffer2, 2 to buffer 3 and 4000 to buffer 4 on first line.
However, it doesn't work. How can I achieve this? I want to read the 2nd line and so on.
Code:
char buffer[100]="";
char buffer2[100]="";
char buffer3[100]="";
char buffer4[100]="";
FILE * pFile=NULL;
pFile = fopen("C: est est.txt", "r");

Im tasked with reading a data file, this is an example snippet
list of trophy winners

1960/61 Tottenham Hotspur Aston Villa Tottenham Hotspur Ipswich Town
1961/62 Tottenham Hotspur Norwich City Ipswich Town Liverpool
1962/63 Manchester Utd Birmingham City Everton Stoke City
The file starts in 1892 and is up to 2011/12, there is data missing for some years due to the wars etc,
once ive read the file, i need to store the data, for me to re-use.
There are a lot of useful link regarding reading data in, but they tend to be with very small files with say 10 lines of numbers.
I've a text file : Random.txt which comprises of
Jade
12MS234
Male
18
Rocky
12MS324
Male
18
Marx
12MS632

Now in my program i've a class
class stud
{
char name[10];
char reg[10];
char gender[10];
int age;
};
Now I've to write a code in c++, where i've to read the given data and store this into 3 objects of stud class(array of objects) ...then further i've to manipulate the above stored data. I think i'm getting error while storing...variables are showing random characters... give me the code.for this program..in C++
I am trying to read a file use the data line by line to create into an object. The current file I have is like this and the code reading the file will be found below.
1223 Fake1 Name1 60 70 80 24 89 add1 Male
1224 Fake2 Name2 61 70 81 80 24 add2 Male
1225 Fake3 Name3 63 70 82 80 89 add3 Male
1226 Fake4 Name4 63 70 83 80 88 add4 Male
The problem I am having is that I need to put delimiters in the file so that a person can have more than one name and also the address can now hold multiple strings until the delimiter.
I would like to change my file to this;
1223 : Fake1 Name1 : 60 : 70 : 80 : 24 :89 : This will be address1 : Male
1224 : Fake2 Name2 : 61 : 70 : 81 : 80 :24 : This will be address2 : Male
1225 : Fake3 Name3 : 63 : 70 : 82 : 80 :89 : This will be address3 : Male
1226 : Fake4 Name4 : 63 : 70 : 83 : 80 :88 : This will be address4 : Male
How can I update the code below so that it can use the delimiters to create an object?
void loadFile(Person people[], int* i) {
ifstream infile("people2.txt");
if ( !infile.is_open()) {
// The file could not be opened
cout << "Error";

I'm basically trying to make a simple program that reads integers out of a text file and only adds the positive ones and not the negatives.
All is well except it won't take the last integer (the last line, I presume.) I took the negative out, nothing to do with that. I put more numbers in and I made the txt file less, no answer. No matter what the last number is, the program won't read it. I've been researching online and I've been seeing that it might be an issue with "while "!inFile.eof())".
Anyway here's the program:
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile;
ofstream outFile;
[Code] .....
Here's the txt file:
5
6
-9
21
3
I'm always getting 32 for some reason.
So I'm reading a file line by line and storing it backwards into a list. So if the file has has this format...
1
2
3
4
The code should store each line in a list as such...
4, 3, 2 ,1
Instead the code will store the last variable in all nodes. So the final list will look like this...
4, 4, 4, 4
Here is my code...
struct node *head = NULL;
int i;
while(read(in, &i, sizeof(int)) != 0) {
struct node *temp = malloc(sizeof(*temp));
temp->line = &i;
temp->next = head;
head = temp;
}
I have a structure
struct Wine
{
string wineName;
int vintage;
int rating;
double price;
};
how can i store the file data below in an array with the structure type???
Dow Vintage Port ;2011;99;82
Mollydooker Shiraz Carnival of Love ;2012;95;75
Prats & Symington Douro Chryseia ;2011;97;55
Quinta do Vale Meão Douro ;2011;97;76

what I need is to get the first integer from a file and assign it to a variable and the others integers to an array. Example: Thats my file content 5 4 6 7 8 0 and that would be the code:
Code:
struct Array{
int n;
int *v;
}

I am reading data from a text file into a program. I am well aware of the subtle distinctions in the mode of data input/entry when using the stream extraction operator, the get() function, and the getline() function.
My problem is that all of them do not read and/or store the newline character alongside the data read!
Any function that reads and stores data and the terminating newline character together??
This is my code!! but it's not working at all.
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main () {
ofstream fout("datain.txt",ios::out);
int array[6][6];

I am doing SerialPort communication program where i am opening the port and reading data from port and storing in one document.
I debug my program and check that my read function is reading the data properly but when checking the document i find only unicode.
Suppose I am sending 1,2,3,4 to port i able to read same but my document showes þÿÿ þÿÿ þÿÿ þÿÿ
//My Read Function which read data from serial port
tInt serialport::Read(tVoid* pvBuffer, tInt nBufferSize) {
tInt nBytesRead = 0;
[Code] ....
Why I am getting unicode instead of 1,2,3,4 in my document ....
I am doing a program and i need to read integers that are in a string and i dont know if i am doing it correctly.
Code:
unsigned int j=0, h1;
char num[100] , str1[100], str2[100], a[100], b[100];
sscanf(str1, "%[^;] ; %[^;] ; %d ", a, b, &h1); the string is : "0048915433190;24/10/2013;13h 7m 47s;13h 8m 59s;0;1;"
And what i want to read with sscanf is the hours, minutes and seconds.
I know to read a strings into array and tables.. what is they are mixed up?? strings are just names ( 3 characters) and there are bunch of table.. the max size was set to 60
ex. text file
JES
DAN
JEN
.

.
01010101
10010101
RAM
JET
01010010
10100101
.... and so on
should i use a while loop?
I have a file with such a format:
string string 8 7 2
string string 7 12 19 -4
string string 1
As you can see I don't know how many numbers there are at the end. I have this code now:
while(!in.eof()) {
kr = 0;
getline(in, pavard, ','); getline(in, vard, ','); getline(in, gr, ',');
while(in.peek()) {
in >> k;
kr += k;
}
in.ignore();
}
in.close();
I tried various combinations with peek() function, but nothing worked.
