how to split a string into words c++

#include<iostream>
#include<bits/stdc++.h>
using namespace std;

int main()
{
    string str="23 156 1645 -2398 77";
    vector<string> words; 
    char delimeter=' ';
    int n=str.size();
    for(int i=0;i<n;i++)
    {
        int j=i;
        while(str[i]!=delimeter && i<n)
            i++;
        string temp=str.substr(j,i-j);
        words.push_back(temp);
    }

}

c++ splitstring example

#include <iostream>
#include <sstream>
#include <vector>

using namespace std;

// for string delimiter
vector<string> split (string s, string delimiter) {
    size_t pos_start = 0, pos_end, delim_len = delimiter.length();
    string token;
    vector<string> res;

    while ((pos_end = s.find (delimiter, pos_start)) != string::npos) {
        token = s.substr (pos_start, pos_end - pos_start);
        pos_start = pos_end + delim_len;
        res.push_back (token);
    }

    res.push_back (s.substr (pos_start));
    return res;
}

int main() {
    string str = "adsf-+qwret-+nvfkbdsj-+orthdfjgh-+dfjrleih";
    string delimiter = "-+";
    vector<string> v = split (str, delimiter);

    for (auto i : v) cout << i << endl;

    return 0;
}

how to split string in c++

#include<iostream>
#include<bits/stdc++.h>
using namespace std;

vector<string> string_burst(string str,char delimeter) 
{
  //condition: works with only single character delimeter, like $,_,space,etc.
    vector<string> words;
    int n=str.length();
    for(int i=0;i<n;i++)
    {
        int j=i;

}

implementing split function in c++

// splits a std::string into vector<string> at a delimiter
vector<string> split(string x, char delim = ' ')
{
    x += delim; //includes a delimiter at the end so last word is also read
    vector<string> splitted;
    string temp = "";
    for (int i = 0; i < x.length(); i++)
    {
        if (x[i] == delim)
        {
            splitted.push_back(temp); //store words in "splitted" vector
            temp = "";
            i++;
        }
        temp += x[i];
    }
    return splitted;
}

how to split string into words c++

#include <string.h>

int main ()

  char str[] ="This is a sample string";
  char *p;
  
  p=strtok(str," ");
  while (p!= NULL)
  {
    cout<<p;
    p=strtok(NULL," ");
  }

c++ string split

std::vector<std::string> &split(const std::string &s, char delim, std::vector<std::string> &elems) {
    std::stringstream ss(s);
    std::string item;
    while(std::getline(ss, item, delim)) {
        elems.push_back(item);
    }
    return elems;
}

c ++ split_string

std::vector<std::string> split_string(const std::string& str,
                                      const std::string& delimiter)
{
    std::vector<std::string> strings;

    std::string::size_type pos = 0;
    std::string::size_type prev = 0;
    while ((pos = str.find(delimiter, prev)) != std::string::npos)
    {
        strings.push_back(str.substr(prev, pos - prev));
        prev = pos + 1;
    }

    // To get the last substring (or only, if delimiter is not found)
    strings.push_back(str.substr(prev));

C++ split string

std::vector<std::string> split(std::string str, char delim = ' ') {
  std::vector<std::string> result;
  size_t start = 0;
  while (start < str.length()) {
    size_t pos = str.find(delim, start);

split string in c++

void simple_tokenizer(string s)
{
    stringstream ss(s);
    string word;
    while (ss >> word) {
        cout << word << endl;

}

split text c++

#include <boost/algorithm/string.hpp>

std::string text = "Let me split this into words";
std::vector<std::string> results;

boost::split(results, text, [](char c){return c == ' ';});

split string in c++

Some of the Most Common used functions of StringStream.
clear() — flushes the stream 
str() —  converts a stream of words into a C++ string object.
operator << — pushes a string object into the stream.
operator >> — extracts a word from the stream.

split string by delimiter cpp

// C++ program to understand the use of getline() function
  
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    string S, T;
  
    getline(cin, S);
  
    stringstream X(S);
  
    while (getline(X, T, ' ')) {
        cout << T << endl;
    }
  
    return 0;
