Program to extract words from a given String

The task is to extract words from a given string. There may be one or more space between words.

Examples:

Input : geeks for geeks
Output : geeks
         for
         geeks

Input : I love   coding.
Output: I 
         love
         coding



We have discussed a solution in the below post.
How to split a string in C/C++, Python and Java?

In this post, a new solution using stringstream is discussed.

1. Make a string stream.
2. extract words from it till there are still words in the stream.
3. Print each word on new line.

This solution works even if we have multiple spaces between words.

// C++ program to extract words from

#include<bits/stdc++.h>
using namespace std;
  
void printWords(string str)
{
    // word variable to store word
    string word;
  
    // making a string stream
    stringstream iss(str);
  
    // Read and print each word.
    while (iss >> word)
        cout << word << endl;
}
  
// Driver code
int main()
{
    string s = "sky is blue";
    printWords(s);
    return 0;
}
