Heya, strange question, is it possible to make c++ read from a text file, and pick out a random line then shove that into a variable...
for example if the text file contained a differant sentence on each line eg

the cat sat on the mat
i ate chicken last night
please use a coaster
can you give me a lift

and so on and so forth, I just want the program to open that file with that list of sentences pick one out and stick it into a variable?

is this possible? please help... thanks alot ^.^

Certainly.

One approach could be to read every line of the text into its own char array (or std::string for convenience) and then randomly pick one of these.
Get familiar with the C++ stream (for file reading) and string (for text storing) classes and then apply this to your example.
