Random length?

I presume that you mean they can use any number of characters, followed
by some kind of terminating character.

Take a look at
std::string, std::getline, std::cin and std::cout

from these headers:
<iostream>
<string>


That allows the user to enter a line (a string terminated with a
carriage return), read it into a string, and then display that string.

This should be described in your favourite C++ reference.
