C++ :: Function To Split The String By Delimiter
Mar 19, 2014
How delimiter work. I need write a function that splits the string by delimiter. Function header is:
vector<string> split(stirng target, string delimiter);
for example, the code inside main calling your function
vector<string> v = split("hiAAAmyAAAnameAAAis", "AAA");
and v should come out as hi my name is
So is it something like
vector<string> split(string target, string delimiter) {
vector<string> word;
string s = "hiAAAmyAAAnameAAAis";
string delimiter = "AAA";

i have a list of date format 1-12-2011 that i get from a txt file.
char date[30];
fstream fin("date.txt");
fin >> date;
how do i split the date array to 3 array of char day[],char month[] and char year[] for my structure list? using delimiter '-' so i get 1 to day, 12 to month and 2011 to year.
struct date{
string day;
string month;
string year;

How do I use a string in place of a character in the function getline?
For example,
getline(infile,lines,'}');
This works fine, but I want the delimiter of } to be "};", but I can't do this as it only takes in characters, not strings.
I want:
getline(infile,lines,"};");
Any way to get around this?

I Need to write a function using C wherein I should do the following:
(i) The function will receive a string in a character pointer
(ii) This string will adhere to the following structure:
"Kentucky+New York+Arizona+Nevada"
The number of states can differ from 4 to 50
The delimiter between States can differ from '+' to ',', hence I would like to pass the delimiter to the function.
(iii) This string should then be sorted alphabetically from left to right.
The above example would then become: "Arizona+Kentucky+Nevada+New York"
(iv) This string needs to be returned from the function using a character pointer.

Write one program that receive a string, tokenize it by ' ' delimiter and show the output, using STL
So, I write:
#include <stack>
#include <iostream>
#include <vector>
#include <string>
using std::stack;
using std::cout;
[Code] .....
And...
Type any string and I'll say its proprieties:
> A B C
String length: 5
Words number: 3
Word 1: (split(input)[0])
A
Word 2: (split(input)[1])
B C
Word 3: (split(input)[2])
C
>
What am I doing wrong?

I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);
[Code] ....
Output of the code is
3 J JD
k
but I want
3
J
JD
K
Also after I split the string is there any way to put the split string into individual string variables.

I have my Arduino send the following string every second:
69.4,69.4,69.4,69.4,69.4,69.4,8.42,100,100,50,50,20,16,10,14
and i currently have my C# code split it and send the values to corresponding text boxes:
// SERIAL READS:
private void myport_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e) {
string RxData = myport.ReadLine();
this.BeginInvoke(new LineReceivedEvent(LineReceived), RxData);
[Code] ....
Now if i were to add true/false values to my arduino string, im not sure to read it. I would like the bool values to enable/disable led jpegs to simulate output status.
rly1_led.enable = newData[15];// if true
Ive tried everything and just cant figure it out. This is my first C# project.

I am having trouble with parsing out string value into a 2D vector. Suppose i have the string "attack at dawn " consisting of 15 characters, i will like to store it into a 2D vector with 5 rows and 3 columns and the result is as follow.
Vector[0][0] = "a"
Vector[0][1] = "t"
Vector[0][2] = "t"
Vector[1][0] = "a"
Vector[1][1] = "c"

I manage to split this str = "abc,def,123"
to s1 = "abc", s2 = "def", s3 = "123" with this piece of code using find and substr.
string str, s1, s2, s3;
getline(cin, str);
unsigned pos1 = str.find(",");
[Code] ....
But what should I do if the len of the string is unknown ?
For example, str = "abc,def,123,ghi,jkl,456,mno" and so on...

how to do this in C#. Need to connect to Oracle db, take a file from directory then read every line of the file. Lines are like this:
123234847656|8800359898818177|A|20130401 14:51:42|
123234847212||D|20130401 14:52:08|
123234847212||M|20130401 14:55:38|
Then will split as string on every '|' char and according to this flag |A|, |D| or |M| I will add/delete/modify information inside. I have trouble with this part with the connection and read/split file and check for the flag A, D or M.

I'm currently trying to code a sorting algorithm program.
let's asume I have a string given: aa, aaa, bbb, bas, zya!
I first of all want to split the given string on commas and '!' tells the program the string ends here and is no part of the last word. lower and upper case is not important at the moment. trying to implement everything with standard libary
output should be like that ofc:
aa
aaa
bas
bbb
zya
I already looked into the bubble sort algorithm and I think it benefits my needs. Just wanted to know how I should start out with the string split.

I'm reading lines from a text file in C++ which contains integer + string + float number(like 3,67 with comma) + string in this order. I need the float number to sort the lines but I couldn't manage to separate the data into the types I can use so far. I tried different kind of functions and the best I could do was such a code;
void main (){
ifstream records;
records.open("records.txt");
int id;
string line;
char name[100];
float gpa;
[Code] ....
This fails at reading the floating number which has comma in it and then last string is read as string starting with the comma and rest of the number. An output example is:
698 John 3 ,67
It doesn't read last string on the line as well. I understand that part but simply I need another read but what I want exactly is to separate one line using "tab" as a seperator into proper data types and then using the numbers as integers, and the grades as floating numbers. How Can I do this?

is it possible in c++ to split string by string? And if yes, then how?
For example I have string:
one|#|two|#|three
I would like to split it by "|#|", not by one char.

Is it possible to fgets() the string (or word) only after a delimiter? I yes then how?
Example: Code: printer, scanner, machine
Also, how can I sscanf() a string with an indefinite number of sizes and assign it to only one variable?
Example:
Code:
str = "I Love C programming 9000";
sscanf(str, "%s %d", strvar, intvar);

I have attached the file that I need to read into a data structure. In the example I am just printing it to the screen. This following code has worked for me before, but now isn't. I have tried in visual studios, and on unix, and neither are running it. I ultimately need it to run on unix.
Example file:
word
book
programming
Here is my function to read in the file.
ifstream file;
string line;
file.open("words.txt");
if(file.is_open()){
while(!file.eof()){
getline(file, line);
cout << line <<endl;
}
}
file.close();

I want to read a binary file using as line separator "ff77" in order to parse further each line one by one with some regex since the file is big. I have a small ruby code shown below, but I'm new in C++, and I don't know how to replicate in C++ what this ruby code does.
Code:
#!/usr/bin/env ruby
BEGIN{ $/="xffx77" } # Line separator = FF77
File.open(ARGV[0],"rb") # Open in binary mode

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 need to split my main() function into two separate functions.Where would the best place be to split it up?
* Read a text file whose name is given on the command line, and for each word:
* if it is an integer, insert it into an array in sorted order
* if it is not an integer, insert it into an array of words.
* Notes: converted to use C++ strings, because C strings are messier.
* Need to grow arrays, need to insert in sorted order.
* Growing arrays might be done the way we grew a C string:
* bigger = new <type> [size+1]
* for(i=0; i<size; i++) {
* bigger[i] = oldarray[i];
