Find words which are greater than given length k using stringstream

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.


Input : str = "hello geeks for geeks 
          is computer science portal" 
        K = 4
Output : hello geeks geeks 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:





// C++ program to find all string 
// which are greater than given length k
// using stringstream
#include <bits/stdc++.h>
using namespace std;
// Function to find all string 
// which are greater than given length k
// using stringstream
void 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 << " ";
// Driver code
int main()
    string str = "geeks for geeks";
    int k = 4;
    findWords(str, k);
    return 0;
