Strings Question

[deadmittens]

So in this program I'm writing, I ask for firstName, lastName, and date.
I would like to output data to a file with the filename format of:
firstName_lastName_date.txt

So I basically need to define another string based on other strings while adding underscores.

Is this even possible? It seems like it'd be overly complicated, but I am interested to see if it can be done.

Thanks in advance for any help you can lend.

string filename = firstName + "_" + lastName + "_" + date + ".txt";
ofstream out( filename.c_str() );

You will need
#include<fstream>
in the header.

I was really overcomplicating it... Thanks!
