fstream

[epiqu1n]

Hey so I'm still learning in programming, and I was wondering how to apply fstream when reading and writing to a file. For example, say I have the following content in a file named words.txt:

"these are words"

Right now I just need to be able to ask a user which number word they want, and then display it. I don't want any whole coding, just a general idea on how to do this.

Stream is continuous, so You must think about search algorithm (in google there is a lot). You can change the position of cursor in stream to the end of file I think but I don't know exactly.

A way could be storing words from the file in a vector and then display the wanted elements of the vector,
another way could be looping through files characters and looking for spaces which divide the words

Haha thanks but I guess I should correct myself, I do want a bit of code, but to help me understand how to apply fstream. For example taking the three words and putting them in as separate entries in an array?

I suggest you a vector than an array as a vector can easily change its size

eg:

vector<string> words;


string tempword;
while (!file.eof())
{
    file >> tempword;//get a word
    words.push_back(tempword);//add the word to the vector
}
