Read the text word by word using the scanf function with the "%s" format. Determine the length of the word using the strlen function.

When using the C++ language, read words into string type variables using the cin function. Use the size method to find the length of the word.

Algorithm realization

Read the word into array $s$.

char s[100];

Read the text word by word until the end of the file. For each word print its length.

while(scanf("%s",s) == 1)
  printf("%d ",strlen(s));

Algorithm realization — C++

Read the text word by word until the end of the file. For each word print its length.

while (cin >> s)
  cout << s.size() << " ";
cout << endl;

Java realization

import java.util.*;

public class Main 
{
  public static void main(String[] args) 
  {
    Scanner con = new Scanner(System.in);
    while(con.hasNext())
    {
      String s = con.next();
      System.out.print(s.length() + " ");
    }
    con.close();
  }
}

Python realization

Read the text line by line until the end of the file.

import sys
for x in sys.stdin:
  x = x.split()

The variable $x$ contains a list of words from one line.

  for i in x:

For each word $i$ from the list $x$ print its length. The lengths of the words are printed on one line, separated by a single space.

    print(len(i), end = ' ')
