I am having troubles how to start creating program which counts letters in words in .txt file and print it if letter number is > 20.. Does someone know how to start or have some similar program to help me..Thank you

Does your data file uses spaces as the word delimiter? Contain no punctuation? Just alphabetical letters?

Read each word in your data file into a std::string. The size of the resulting string is the number of letters.

Loop for each word and success.

Just to show an example, because I don't think the tutorial shows a good example that uses >> for input.

// Example program
#include <iostream>
#include <string>
#include <fstream>

int main()
{
    // Assumes file has words separated by whitespace
    std::ifstream file("words.txt"); 
    
    // read in a word
    std::string word;
    file >> word; // operator>> separates each word by whitespace
    
    // print length
    std::cout << word.length() << '\n';
}
