Answer 1

You can use array of string values(write sentences there as elements of that array), after that you can generate a random number from 0 to (length of array-1) & use it to take out a random sentence from array & print it.
//for printing multiple lines, you can do something like generating random number for each line & see whether it is even or odd(using %2==0) to decide printing of that line.

Answer 2

you can make a function with local static array of strings or std::vector with all strings you want then return a random one every call at least I know you can make a use of the silly old rand();
oh and if you want it to be unique all you have to do is to replace the used string with anything and add an if statement just before the end of the function .....you can do it .
