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. 

Examples:

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: 

Implementation:

C++

// 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 << " ";
            count++;
        }
    }
}

// Driver code
int main()
{
    string str = "geeks for geeks";

    int k = 4;

    findWords(str, k);

    return 0;
}

Output

geeks geeks
