Splitting a C++ string by new line without using string stream

Question

Let's say I have a string "file1\nfile2\nfile3".

I want to print out:

file1
file2
file3

How can I do this without using a string stream?

Note: When I say string, I mean the string object in C++.

I'm sorry if this is a stupid question; I'm completely new to C++;

Why don't you just print out the string as is, without splitting it at all? — aschepler, Sep 09 '17 at 22:34

If you are "completely new to C++", then the way you need to learn C++ is [by reading a good book](https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list), or attending a class. You are not going to learn C++ by asking basic questions, one at a time, on some web site and hoping that you'll get an answer in the next day, or two. — Sam Varshavchik, Sep 09 '17 at 23:14
Crap. So much for my proposed programming text: Learn C++ in 365 years. — user4581301, Sep 09 '17 at 23:32

The following should work and lets you specify a multichar delim:

void split_and_print(const std::string & data, const std::string & delim =std::string{"\n"}){
    if (!delim.length()){
        std::cout<<data<<std::endl;
        return;
    }
    auto last  = data.begin();
    auto found = last;
    while (found != data.end()){
        found = std::search(last, data.end(), delim.begin(), delim.end());
        std::cout<<std::string(last, found)std::endl;
        last = found + delim.length();   
    }
}
