Question:

How would you write multiple lines of text out to a file? Write a short function that does so.

Justin C.
Answer:

Text files can easily be written using the standard library class ofstream with the stream operators. This example assumes that the lines "#include <ofstream>" and "using namespace std;" are present in the source file. void outputGreeting(const char *filename) { ofstream file(filename); file << "Hello!" <<endl; file << "This is line 2." <<endl; file << "... and this is the last line." file.close(); }
