C++ Remove new line from multiline string

Question

Whats the most efficient way of removing a \'newline\' from a std::string?

Answer 1

Another way to do it in the for loop

void rm_nl(string &s) {
    for (int p = s.find("\n"); p != (int) string::npos; p = s.find("\n"))
    s.erase(p,1);
}

Usage:

string data = "\naaa\nbbb\nccc\nffffd\n";
rm_nl(data); 
cout << data; // data = aaabbbcccffffd
