Is there a function like fgets() but to read repeatedly every line from a string array like this?
char buf[] = "line1\n
line2\n
line3\n
...
";

use std::istringstream::getline() and tell it to use '\n' as a delimiter...

#include <iostream>
#include <string>
#include <sstream>

int main(int argc, char* argv[])
