# Find words which are greater than given length k using stringstream

• Last Updated : 01 Sep, 2022

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```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

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 ` `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 `
