    Split a char vector

    I have a char vector with text in it.

    I'd like to split it into strings at every new line.

    Is it better to assign the vector to a string first or is there a function that can do this with the vector?

    Of course you can do this with the vector directly: it's a matter of finding the new line sequence, and then constructing a string from a starting index to the index of the new line sequence.

    On the other hand, it might be easier with a std::string object. Since you're going to treat the data like a string anyway, why not use a std::string instead of a vector of char to begin with?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    My vector is used as an unsigned char array, I guess I could assign a string object to an unsigned char array too.

    Thank you laserlight.
