Given a string containing space-separated words and a number K. The task is to find and print all those words whose length is greater than K using stringstream in C++. A general solution to solve this problem using loops is discussed in the previous article. In this article, a solution using stringstream in C++ will be discussed.Â
Examples:
Input : str = "hello neveropen for neveropen
is computer science portal"
K = 4
Output : hello neveropen neveropen computer
science portal
Input : str = "string is fun in python"
K = 3
Output : string python
The idea is to use stringstream to create a stream by splitting the given string into tokens and then process the stream and print the words with length greater than K. Below is the implementation of the above idea:Â
Implementation:
C++
// C++ program to find all string// which are greater than given length k// using stringstreamÂ
#include <bits/stdc++.h>using namespace std;Â
// Function to find all string// which are greater than given length k// using stringstreamvoid findWords(string str, int K){    string word;         // using stringstream to break    // the string into tokens    stringstream ss(str);         int count = 0;    while (ss >> word) { // reading words        if (word.size() > K) {            cout << word << " ";            count++;        }    }}Â
// Driver codeint main(){Â Â Â Â string str = "neveropen for neveropen";Â Â Â Â Â Â Â Â Â int k = 4;Â
    findWords(str, k);         return 0;} |
Java
// Java program to find all string// which are greater than given length k// using StringTokenizerimport java.util.*;Â
class Main{Â
  // Function to find all string  // which are greater than given length k  // using StringTokenizer  static void findWords(String str, int K)  {    StringTokenizer st = new StringTokenizer(str);    int count = 0;    while (st.hasMoreTokens()) { // reading words      String word = st.nextToken();      if (word.length() > K) {        System.out.print(word + " ");        count++;      }    }    if (count == 0)      System.out.print(      "No word is greater than length " + K);  }Â
  // Driver code  public static void main(String[] args)  {    String str = "neveropen for neveropen";    int k = 4;Â
    findWords(str, k);  }}Â

Python3
# Python program to find all string# which are greater than given length k# using split methodÂ
def find_words(string, k):    # split the string into words    words = string.split()    count = 0Â
    # iterate through each word    for word in words:        # check if the length of the word is greater than k        if len(word) > k:            print(word, end=' ')            count += 1Â
    if count == 0:        print(f"No word is greater than length {k}")Â
# Driver codestring = "neveropen for neveropen"k = 4find_words(string, k) |
Javascript
// JavaScript program to find all string// which are greater than given length kÂ
function find_words(string, k) {    // split the string into words    let words = string.split(' ');    let count = 0;Â
    // iterate through each word    for (let word of words) {        // check if the length of the word is greater than k        if (word.length > k) {            console.log(word);            count++;        }    }Â
    if (count === 0) {        console.log(`No word is greater than length ${k}`);    }}Â
// Driver codelet string = "neveropen for neveropen";let k = 4;find_words(string, k); |
C#
using System;using System.Collections.Generic;using System.Collections;using System.Linq;// C# program to find all string// which are greater than given length kÂ
Â
class HelloWorld {         public static void find_words(string str,int k) {        // split the string into words        string[] words = str.Split(' ');        int count = 0;Â
        // iterate through each word        for (int i = 0; i < words.Length; i++) {                         string word = words[i];                         // check if the length of the word is greater than k            if (word.Length > k) {                Console.Write(word + " ");                count = count + 1;            }        }Â
        if (count == 0) {            Console.WriteLine("No word is greater than length ", k);        }    }         static void Main() {                 // Driver code        string str = "neveropen for neveropen";        int k = 4;        find_words(str, k);    }}Â
